Introduction: The testicular regression syndrome (TRS) is a form of differences of sex development (DSD) in which the testes differentiate and function during early embryonic development, but subsequently regress. The clinical phenotype of TRS often overlaps with that of partial gonadal dysgenesis (PGD). Previous studies have demonstrated a causal association between TRS/ PGD and heterozygous missense variants of DHX37. Methods: We enrolled 11 Japanese 46,XY individuals (from 10 families) with TRS/PGD who exhibited undetected or hypoplastic testes, Müllerian duct regression, and low serum testosterone or anti- Müllerian hormone levels. The subjects underwent targeted sequencing of 36 known causative genes for DSD, PCR-based Sanger sequencing of DHX37, or whole-exome sequencing. Results: Previously described pathogenic variants or novel nonsense variants (SRY, NR5A1, and DMRT1) were observed in four out of 10 families. Additionally, we identified two heterozygous rare variants of DHX37 in four families: a previously reported pathogenic variant (c.923G>A, p.Arg308Gln) in three and a novel likely pathogenic variant (c.1882A>C, p.Thr628Pro) in one. The external genitalia of patients with the DHX37 variants varied from female-type to male-type without micropenis. Eighty percent of Japanese patients with TRS/PGD had monogenic disorders including DHX37 variant being the most commonly identified (40%). The external or internal genital phenotype of TRS/PGD overlaps between DHX37 variant carriers and others. Conclusions: DHX37 variant is one of the common genetic causes in Japanese patients with TRS/PGD without Müllerian derivatives. Genetic test is helpful in detecting DHX37- related TRS/PGD because of the phenotypic diversity of the external genitalia in this disorder.

Objectives: To establish age-specific reference values for the arm span and arm span/height ratio of the Japanese population in children and adolescence and elucidate their characteristics compared with those of other populations. Study Design: We analyzed data from a national survey on the body sizes of Japanese people conducted between 1992 and 1994 by the Research Institute of Human Engineering for Quality Life. This study was an observational cross-sectional study, including 6089 boys and 4970 girls aged between 5.5 and 18.5 years. We constructed the reference values and delineated the reference curves for the arm span and arm span/height ratio of the Japanese population in childhood and adolescence using the LMS method. The references were compared with those of the Dutch and Turkish populations using the reference curve of 0 standard deviation. Results: The arm span of the Japanese population increased throughout childhood, with a particularly large increase at the age of puberty. The arm span/height ratio also increased slowly throughout childhood. The Japanese population had a smaller arm span/height ratio than the Dutch and Turkish populations of all ages in childhood and adolescence. Moreover, the arm span/height ratio of the Japanese population reached a constant value at an earlier age than in the Dutch and Turkish populations. Conclusions: We constructed the first reference values for the arm span of Japanese children and adolescents. The Japanese population has shorter arm lengths in relation to their height, and their arm span/height ratio reaches a constant value at an earlier age, compared with the Dutch and Turkish populations.

Recovery from Atrophic Autoimmune Thyroiditis in a Child: Thyroid Stimulation-Blocking Antibody as a Prognostic Marker

Kusano C., Hori N., Hasegawa T., Narumi S.

Hormone Research in Paediatrics 2025

ISSN 16632818

Introduction: Atrophic autoimmune thyroiditis (AAT) is a form of autoimmune hypothyroidism characterized by the absence of a goiter. Thyroid stimulation-blocking antibody (TSBAb) has been detected in a subset of pediatric AAT cases. Although the disappearance of TSBAb has been related with the recovery of thyroid function in adult AAT cases, similar outcomes have not been documented in pediatric cases. Case Presentation: A 2-year-old Japanese boy presented for evaluation of stunted growth from1 year 10 months of age. Tests for congenital hypothyroidism were negative on newborn screening, and he had no significant medical history. However, he showed symptoms of hypothyroidism (inactiveness, hair loss, dry skin), and primary hypothyroidism was confirmed by blood test (serum TSH level, 818 mU/L; serum free T4 level, <0.40 ng/ dL). The patient exhibited a unique antibody profile: positive for TSH receptor antibody (TRAb) and TSBAb and negative for anti-thyroglobulin antibody (TgAb) and antiperoxidase antibody (TPOAb). He was treated with levothyroxine, after which his growth was normalized. During the 8-year follow-up, the patient's TSBAb levels decreased, allowing for the discontinuation of levothyroxine therapy. Conclusion: We reported the case of a 2-year-old boy diagnosed with AAT who presented with a characteristic antibody profile, negative for TgAb and TPOAb, but positive for TRAb and TSBAb. During 8 years of follow-up, TSBAb seroconversion to negative was observed, leading to treatment discontinuation at age 10 years. This case suggests that monitoring of TSBAb after a diagnosis of AAT may be used to determine treatment discontinuation even in children.

We review the imaging findings in pediatric thyroid diseases that necessitate prompt diagnosis and timely medical intervention. Congenital hypothyroidism particularly represents a critical pediatric emergency. Ultrasonography stands as the primary modality for accurately assessing thyroid morphology and identifying thyroid dysgenesis.123I-scintigraphy mirrors iodine metabolism and thyroid hormone synthesis, and the concurrent application of perchlorate (perchloride discharge test) elucidates the pathogenesis of thyroid dyshormonogenesis. Nonetheless, radioiodine scintigraphy has seen limited utilization due to the intricacies of pre-test preparation.99mTc-pertechnetate scintigraphy demonstrates high sensitivity in delineating thyroid tissues with minimal radiation exposure, facilitating the diagnosis of thyroid dysgenesis. Additionally, we have included brief insights on the imaging characteristics of central hypothyroidism, thyroiditis, and thyroid masses.

A Case of Penttinen Syndrome With Radiographic Acroosteolysis From Age 3 Years

Shimura K., Toki M., Tsujioka Y., Nishimura G., Ishii T., Hasegawa T.

American Journal of Medical Genetics, Part A 2025

ISSN 15524825

Premature aging syndrome, Penttinen type (Penttinen syndrome) is a progeroid syndrome with facial alterations (thin hair and progressive recession of the maxillozygomatic bones with pseudoprognathism), skin abnormalities (scleroderma with epidermal and dermal atrophy, lipoatrophy, chronic ulcers, and keloid-like hypertrophic lesions), corneal changes (vascularization and opacity), cerebral vascular anomalies, and acroosteolysis. This syndrome is caused by heterozygous, gain-of-function pathogenic variants in the PDGFRB gene. Only 10 affected individuals have been reported to date, and thus the phenotypic spectrum of the disorder, particularly in early childhood, remains elusive. We reported here the clinical course of an affected male from early childhood to young adulthood. Thin limbs and short fingers attracted medical attention at age 3 years, at which time he had already developed maxillary hypoplasia, keloids, and acroosteolysis, all of which progressively worsened with age. Joint contractures and scoliosis became apparent during adolescence. Progressive maxillary recession and scleroderma remarkably altered his facial gestalt over time, including the development of exophthalmos, small auricles, short philtrum, and small mouth. Sanger sequencing identified a recurrent, de novo pathogenic variant in the PDGFRB gene (c.1994T > C, p.Val665Ala). This report on the clinical course through childhood provides additional insight into the natural history of Penttinen syndrome.

Introduction: Non-autoimmune hyperthyroidism (NAH) is a rare genetic disorder caused by germline-activating variants in the TSH receptor (TSHR) gene. While most NAH-related TSHR variants are located in the seven-transmembrane domain (7TMD), three variants (p.Leu267Phe, p.Ser281Asn, and p.Asn406Ser) have been identified in the extracellular domain (ECD), with p.Leu267Phe previously not showing constitutively active in vitro. Methods: We searched for TSHR variants in a Japanese family with NAH using PCR-based direct sequencing. We created three ECD variants (p.Leu267Phe, p.Ser281Asn, and p.Asn406Ser) and a series of variants in which Leu267 was mutated to 18 amino acids other than Leu and Phe. Based on the cryo-electron microscopic structures, we evaluated the structure-function relationship of TSHR. We compared their cAMP-producing capacities to WT-TSHR in the luciferase activity assay using HEK293 cells. Western blot and fluorescence immunostaining were performed using HA-tagged TSHR vectors to compare Leu267Phe-TSHR with WT-TSHR. Results: A heterozygous TSHR variant (p.Leu267Phe) was identified. Comparison of the cryo-electron microscopy structures of the activated and inactivated TSHRs revealed a significant change in the ECD structure around Leu267. The ligand-independent cAMP-producing capacities compared to WT-TSHR were 238 ± 20% (mean ± SEM) for Leu267Phe. Of all 19 possible variants created through systematic mutagenesis, only Leu267Phe-TSHR and Leu267Tyr-TSHR exhibited significantly higher ligand-independent cAMP-producing capacities. Immunoblotting and fluorescence immunostaining showed that the Leu267Phe variant did not affect protein expression levels and intracellular localization of TSHR. Discussion/Conclusion: Leu267Phe-TSHR causes NAH. Substituting Leu267 to aromatic amino acids may shift the equilibrium of the TSHR state toward activation.

Wnt/β-catenin signaling is essential for adrenocortical development. Zinc and ring finger 3 (ZNRF3), an E3 ubiquitin ligase that attenuates Wnt/β-catenin signaling, is negatively regulated by R-spondin via an extracellular domain that is partially encoded by exon 2 of ZNRF3. We recently identified ZNRF3 exon 2 deletions in three individuals with congenital adrenal hypoplasia. ZNRF3 exon 2 deletion impairs R-spondin binding, thereby attenuating β-catenin expression and eventually leading to the development of congenital adrenal hypoplasia. To elucidate the influence of ZNRF3/Znrf3 exon 2 deletion on adrenocortical development, we generated homozygous Znrf3 exon 2 deletion (Znrf3Δ2/Δ2) mice. Whereas the adrenal glands of Znrf3Δ2/Δ2 mice did not show gross morphological changes at birth, moderate hyperplasia of the zona fasciculata (ZF), dispersed medulla arrangement, and a radially spreading zone with macrophage infiltration between the ZF and medulla were observed at 6 weeks of age. 20α-hydroxysteroid dehydrogenase, a marker of the adrenal X-zone, was hardly detected by immunostaining, and gene expression was significantly downregulated. The number of activated β-catenin-positive cells decreased in the zona glomerulosa, consistent with the results of in situ hybridization for Axin2, a Wnt/β-catenin target gene. Plasma ACTH and serum corticosterone levels in Znrf3Δ2/Δ2 mice did not differ significantly from those in wild-type mice. These results show a species-specific difference in the effects of ZNRF3/Znrf3 exon 2 deletions in humans and mice; Znrf3Δ2/Δ2 mice do not develop congenital adrenal hypoplasia but instead exhibit moderate ZF hyperplasia, dispersed medulla arrangement, X-zone dysplasia, and macrophage infiltration occurred in the inner cortex.

Genetic variants involving steroidogenic acute regulatory protein cause lipoid congenital adrenal hyperplasia, which is characterized by impaired steroidogenesis in the adrenal glands and gonads. Functional assessment of variant STAR proteins is necessary for an accurate genetic diagnosis. Ideally, steroidogenic cells should be used to assess the functionality of STAR proteins, but the presence of endogenous STARs in steroidogenic cells precludes such a method. Here, we generated Star-edited cells from steroidogenic Y1 mouse adrenocortical tumor cells by genome editing. Star-edited Y1 cells exhibited very low but measurable cAMP-dependent pregnenolone production. Furthermore, stimulation of the cAMP pathway for 2 weeks resulted in the formation of lipid droplets in the cytoplasm of Star-edited Y1 cells, which resembled the histology of the adrenal glands of patients with lipoid congenital adrenal hyperplasia. The steroidogenic defect of Star-edited Y1 cells can be restored by transient overexpression of mouse Star. We found that human STAR can also restore defective steroidogenesis in Star-edited Y1 cells, and we were able to construct a novel in vitro system to evaluate human STAR variants. Collectively, we established Star-edited Y1 cells that retain the steroidogenic pathway downstream of the Star protein. Star-edited Y1 cells recapitulate the functional and morphological changes of lipoid congenital adrenal hyperplasia and can be used to evaluate the functionality of human STAR variants.

Context: Thyroglobulin (Tg), encoded by TG, is essential for thyroid hormone synthesis. TG defects result in congenital hypothyroidism (CH). Most reported patients were born before the introduction of newborn screening (NBS). Objective: We aimed to clarify the phenotypic features of patients with TG defects diagnosed and treated since the neonatal period. Methods: We screened 1061 patients with CH for 13 CH-related genes and identified 30 patients with TG defects. One patient was diagnosed due to hypothyroidism-related symptoms and the rest were diagnosed via NBS. Patients were divided into 2 groups according to their genotypes, and clinical characteristics were compared. We evaluated the functionality of the 7 missense variants using HEK293 cells. Results: Twenty-seven rare TG variants were detected, including 15 nonsense, 3 frameshift, 2 splice-site, and 7 missense variants. Patients were divided into 2 groups: 13 patients with biallelic truncating variants and 17 patients with monoallelic/biallelic missense variants. Patients with missense variants were more likely to develop thyroid enlargement with thyrotropin stimulation than patients with biallelic truncating variants. Patients with biallelic truncating variants invariably required full hormone replacement, whereas patients with missense variants required variable doses of levothyroxine. Loss of function of the 7 missense variants was confirmed in vitro. Conclusion: To our knowledge, this is the largest investigation on the clinical presentation of TG defects diagnosed in the neonatal period. Patients with missense variants showed relatively mild hypothyroidism with compensative goiter. Patients with only truncating variants showed minimal or no compensative goiter and required full hormone replacement.

Context: Adrenal crisis (AC) is a life-threatening complication that occurs during follow-up of patients with adrenal insufficiency (AI). No prospective study has thoroughly investigated AC in children with primary and secondary AI. Objective: This work aimed to determine the incidence and risk factors for AC in patients with pediatric-onset AI. Methods: This multicenter, prospective cohort study conducted in Japan enrolled patients diagnosed with AI at age ≤15 years. The incidence of AC was calculated as events per person-year (PY), and risk factors for AC were assessed using Poisson regression multivariable analysis. Results: The study population comprised 349 patients (164 male, 185 female) with a total follow-up of 961 PY. The median age at enrollment was 14.3 years (interquartile range [IQR] 8.5-21.2 years), and the median follow-up was 2.8 years (IQR 2.2-3.3 years). Of these patients, 213 (61%) had primary AI and 136 (39%) had secondary AI. Forty-one AC events occurred in 31 patients during the study period. The calculated incidence of AC was 4.27 per 100 PY (95% CI, 3.15-5.75). Poisson regression analysis identified younger age at enrollment (relative risk [RR] 0.93; 95% CI, 0.89-0.97) and increased number of infections (RR 1.17; 95% CI, 1.07-1.27) as significant risk factors. Female sex (RR 0.99; 95% CI, 0.53-1.86), primary AI (RR 0.65; 95% CI, 0.30-1.41), or equivalent dosage of hydrocortisone per square meter of body area (RR 1.02; 95% CI, 0.96-1.08) was not a significant risk factor. Conclusion: A substantial proportion of patients with pediatric-onset AI experience AC. Younger age and an increased number of infections are independent risk factors for developing AC in these patients.

Biallelic pathogenic variants in RMRP, the gene encoding the RNA component of RNase mitochondrial RNA processing enzyme complex, have been reported in individuals with cartilage hair hypoplasia (CHH). CHH is prevalent in Finnish and Amish populations due to a founder pathogenic variant, n.71A > G. Based on the manifestations in the Finnish and Amish individuals, the hallmarks of CHH are prenatal-onset growth failure, metaphyseal dysplasia, hair hypoplasia, immunodeficiency, and other extraskeletal manifestations. Herein, we report six Japanese individuals with CHH from four families. All probands presented with moderate short stature with mild metaphyseal dysplasia or brachydactyly. One of them had hair hypoplasia and the other immunodeficiency. By contrast, the affected siblings of two families showed only mild short stature. We also reviewed all previously reported 13 Japanese individuals. No n.71A > G allele was detected. The proportions of Japanese versus Finnish individuals were 0% versus 70% for birth length < −2.0 SD, 84% versus 100% for metaphyseal dysplasia and 26% versus 88% for hair hypoplasia. Milder manifestations in the Japanese individuals may be related to the difference of genotypes. The mildest form of CHH phenotypes is mild short stature without overt skeletal alteration or extraskeletal manifestation and can be termed “RMRP-related short stature”.

Insufficient thyroid hormone production in newborns is referred to as congenital hypothyroidism. Multinodular goiter (MNG), characterized by an enlarged thyroid gland with multiple nodules, is usually seen in adults and is recognized as a separate disorder from congenital hypothyroidism. Here we performed a linkage analysis of a family with both nongoitrous congenital hypothyroidism and MNG and identified a signal at 15q26.1. Follow-up analyses with whole-genome sequencing and genetic screening in congenital hypothyroidism and MNG cohorts showed that changes in a noncoding TTTG microsatellite on 15q26.1 were frequently observed in congenital hypothyroidism (137 in 989) and MNG (3 in 33) compared with controls (3 in 38,722). Characterization of the noncoding variants with epigenomic data and in vitro experiments suggested that the microsatellite is located in a thyroid-specific transcriptional repressor, and its activity is disrupted by the variants. Collectively, we presented genetic evidence linking nongoitrous congenital hypothyroidism and MNG, providing unique insights into thyroid abnormalities.

Context: Primary adrenal insufficiency (PAI) is a life-threatening condition characterized by the inability of the adrenal cortex to produce sufficient steroid hormones. E3 ubiquitin protein ligase zinc and ring finger 3 (ZNRF3) is a negative regulator of Wnt/β-catenin signaling. R-spondin 1 (RSPO1) enhances Wnt/β-catenin signaling via binding and removal of ZNRF3 from the cell surface. Objective: This work aimed to explore a novel genetic form of PAI. Methods: We analyzed 9 patients with childhood-onset PAI of biochemically and genetically unknown etiology using array comparative genomic hybridization. To examine the functionality of the identified single-exon deletions of ZNRF3 exon 2, we performed three-dimensional (3D) structure modeling and in vitro functional studies. Results: We identified various-sized single-exon deletions encompassing ZNRF3 exon 2 in 3 patients who showed neonatal-onset adrenal hypoplasia with glucocorticoid and mineralocorticoid deficiencies. Reverse-transcriptase polymerase chain reaction (RT-PCR) analysis showed that the 3 distinct single-exon deletions were commonly transcribed into a 126-nucleotide deleted mRNA and translated into 42-amino acid deleted protein (ΔEx2-ZNRF3). Based on 3D structure modeling, we predicted that interaction between ZNRF3 and RSPO1 would be disturbed in ΔEx2-ZNRF3, suggesting loss of RSPO1-dependent activation of Wnt/β-catenin signaling. Cell-based functional assays with the TCF-LEF reporter showed that RSPO1-dependent activation of Wnt/β-catenin signaling was attenuated in cells expressing ΔEx2-ZNRF3 as compared with those expressing wild-type ZNRF3. Conclusion: We provided genetic evidence linking deletions encompassing ZNRF3 exon 2 and congenital adrenal hypoplasia, which might be related to constitutive inactivation of Wnt/β-catenin signaling by ΔEx2-ZNRF3.

Context: Recently developed long-read sequencing (LRS) technology has been considered an option for CYP21A2 analysis. However, the clinical use of LRS for CYP21A2 analysis is limited. Objective: This study’s objective is to develop an efficient and low-cost LRS system for CYP21A2 screening. Methods: A DNA fragment library was prepared in a single polymerase chain reaction (PCR) that covers the entire CYP21A2 gene and all known junctions caused by TNXB gene structural rearrangements, yielding a single 8-kb product of CYP21A2 or CYP21A1P/CYP21A2 chimera. After barcoding, the PCR products were sequenced on a MinION-based platform with Flongle Flow Cell R9.4.1 and R10.4.1. Results: The reference genotypes of 55 patients with 21-hydroxylase deficiency (21OHD) were established using the conventional method with multiplex ligation-dependent probe amplification (MLPA) and nested PCR. LRS using Flongle Flow Cell R9.4.1 yielded consistent results. Additionally, the recently updated LRS “duplex” analysis with Flongle flow cell R10.4.1 was tested to reveal an advantage of accurately sequencing a variant located on the homopolymer region. By introducing a barcode system, the cost was reduced to be comparable to that of conventional analysis. A novel single-nucleotide variation was discovered at the acceptor site of intron 7, c.940-1G > C. We also identified a subtype of the classical chimeric junction CH2, “CH2a,” in the region from the latter part of intron 5 to exon 6. Conclusion: We successfully established a novel low-cost and highly accurate LRS system for 21OHD genetic analysis. Our study provides insight into the feasibility of LRS for diagnosing 21OHD and other genetic diseases caused by structural rearrangements.

The zona fasciculata (zF) in the adrenal cortex contributes to multiple physiological actions through glucocorticoid synthesis. The size, proliferation, and glucocorticoid synthesis characteristics are all female biased, and sexual dimorphism is established by androgen. In this study, transcriptomes were obtained to unveil the sex differentiation mechanism. Interestingly, both the amount of mRNA and the expressions of nearly all genes were higher in females. The expression of Nr5a1, which is essential for steroidogenic cell differentiation, was also female biased. Whole-genome studies demonstrated that NR5A1 regulates nearly all gene expression directly or indirectly. This suggests that androgen-induced global gene suppression is potentially mediated by NR5A1. Using Nr5a1 heterozygous mice, whose adrenal cortex is smaller than the wild type, we demonstrated that the size of skeletal muscles is possibly regulated by glucocorticoid synthesized by zF. Taken together, considering the ubiquitous presence of glucocorticoid receptors, our findings provide a pathway for sex differentiation through glucocorticoid synthesis.

Hypothalamic-pituitary Langerhans cell histiocytosis (HP-LCH) is often associated with arginine vasopressin deficiency (AVD). Patients with AVD caused by HP-LCH rarely develop an impaired osmotic threshold for thirst (OTT). Improvement in OTT among such patients has not been reported in the literature. To our knowledge, here we report the first case of AVD due to HP-LCH in which hypodipsia resolved during chemotherapy. A nine-year-old Japanese girl presented with polydipsia, polyuria, anorexia, and hypernatremia (149.8 mEq/L) and was diagnosed with AVD secondary to HP-LCH. Visual analog scale examination showed a reduced OTT following the water deprivation test. During chemotherapy for Langerhans cell histiocytosis (LCH), serum sodium concentrations became stable between 138.9 and 142.9 mEq/L under the replacement of desmopressin. Repeated visual analog scale examinations showed that she experienced a sense of thirst at a serum sodium concentration of 142.3–144.6 mEq/L, at which she did not experience any thirst prior to the initiation of chemotherapy. These data suggest that chemotherapy directly improved the OTT in our patient. Improved mechanical compression or infiltration of the hypothalamus related to OTT may lead to the recovery of the sense of thirst. This report highlights the potential role of chemotherapy for solitary HP-LCH in patients with hypodipsia and AVD.

There have been no reports comparing neonatal external genitalia of 5α-reductase deficiency (5αRD) with those of other 46,XY differences of sex differentiation (DSD). This study enrolled 31 Japanese cases of 46,XY DSD whose external genitalia was examined during the neonatal period; four were diagnosed as 5αRD and 15 were defined as non-5αRD by genetic analysis of SRD5A2 or urinary steroid metabolites. We compared the following characteristics between 5αRD and non-5αRD groups, adjusting the severity of undermasculinization of the external genitalia: stretched penile length (SPL), glans width, location of the external urethral opening, and proportion of undescended testis. The external genitalia of all the 5αRD cases were Quigley classification grade 2 or 3. We compared the phenotypes between the four 5αRD cases and 11 non-5αRD cases with grade 2 or 3. The median (range) of SPL in the 5αRD group (14 mm [11-16]) was significantly lower than that in the non-5αRD group (22 mm [15-29]) (p = 0.003). An SPL cut-off value of <15 mm yielded a sensitivity of 50% (95% confidence interval [CI]; 7–93%) and specificity of 100% (95% CI, 72–100%) for discriminating between the groups. The median glans width, location of the external urethral opening, and proportion of undescended testis were not significantly different between the groups. The SPL of 5αRD in Quigley classification grade 2 or 3 was significantly shorter than that of other 46,XY DSDs with the equivalent grade.

Annals of Human Biology 51 ( 1 ) 2024

ISSN 03014460

Background: The high prevalence of underweight in young women has become a serious health problem in Japan. When and how young women reach a low body mass index (BMI) has not been clarified. Aim: To clarify the characteristics of BMI standard deviation scores (BMI SDS) trajectory of young Japanese women with underweight. Subjects and methods: A total of 601 Japanese female university students aged 20 years were classified into underweight and healthy weight groups. Their school health check-up data were available from the ages of 6 to 20 years. We evaluated the estimated mean values of BMI SDS at each age and differences in BMI SDS (ΔBMI SDS) from 6 years to each age using a mixed-effects model and compared between the two groups at each age. Results: In the underweight group, the BMI SDS at every age (−1.67 to −0.91) and the ΔBMI SDS after 16 years of age (−0.76 to −0.38) were significantly lower than those in the healthy weight group (−0.41 to −0.13, −0.07 to 0.04), respectively. Conclusion: Young Japanese women with underweight have at least two characteristics of BMI SDS trajectory: being constitutionally underweight and shifting their weight status from baseline towards underweight in their late teens.

Objectives: The role of serum fibroblast growth factor 23 (FGF23) level in early neonatal period on the diagnosis of X-linked hypophosphatemic rickets (XLH) remains unclear. Case presentation: Two female patients from the first pedigree had an affected mother, and the other female from the second pedigree had an affected father. In all three cases, FGF23 levels were high in cord blood and peripheral blood at day 4-5. Additionally, the FGF23 levels considerably increased from birth to day 4-5. We identified a PHEX pathogenic variant and initiated treatment during infancy in each case. Conclusions: In neonates with a parent diagnosed as PHEX-associated XLH, FGF23 in cord blood and peripheral blood at day 4-5 may be useful markers for predicting the presence of XLH.

Central nervous system germ cell tumors (CNSGCTs) are rare neoplasms which usually develop in the midline structures. They are occasionally involved in off-midline structures of the brain. Here, we report an extremely rare case of an intracranial germinoma in the lateral ventricle. The patient was a 10-year-old boy with a 1-year history of polydipsia and polyuria. Brain magnetic resonance imaging (MRI) showed a relatively homogeneously enhancing lesion in the lateral ventricle, and the posterior pituitary gland was not hyperintense on T1-weighted imaging. Subependymoma was suspected, and tumor removal operation was performed; however, because the intraoperative pathological investigation revealed germinoma, we could only perform partial removal of the tumor. Postoperative histology also confirmed germinoma. Then, the patient received chemotherapy, followed by radiation therapy. MRI showed no recurrence for 6 years after treatment. Intracranial germinoma in the lateral ventricle is extremely rare. The diagnosis is occasionally challenging, especially when the tumors are located in atypical locations. This paper presents a literature review of previously described CNSGCTs of the lateral ventricle to improve awareness of CNSGCTs in atypical locations. We also consider the relationship between imaging findings and clinical manifestations.

POU1F1/Pou1f1 c.143-83A > G Variant Disrupts the Branch Site in Pre-mRNA and Leads to Dwarfism

POU Class 1 Homeobox1 (POU1F1/Pou1f1) is a well-established pituitary-specific transcription factor, and causes, when mutated, combined pituitary hormone deficiency in humans and mice. POU1F1/Pou1f1 has 2 isoforms: the alpha and beta isoforms. Recently, pathogenic variants in the unique coding region of the beta isoform (beta domain) and the intron near the exon-intron boundary for the beta domain were reported, although their functional consequences remain obscure. In this study, we generated mice carrying the Pou1f1 c.143-83A>G substitution that recapitulates the human intronic variant near the exon-intron boundary for the beta domain. Homozygous mice showed postnatal growth failure, with an average body weight that was 35% of wild-type littermates at 12 weeks, which was accompanied by anterior pituitary hypoplasia and deficiency of circulating insulin-like growth factor 1 and thyroxine. The results of RNA-seq analysis of the pituitary gland were consistent with reduction of somatotrophs, and this was confirmed immunohistochemically. Reverse transcription polymerase chain reaction of pituitary Pou1f1 mRNA showed abnormal splicing in homozygous mice, with a decrease in the alpha isoform, an increase in the beta isoform, and the emergence of the exon-skipped transcript. We further characterized artificial variants in or near the beta domain, which were candidate positions of the branch site in pre-mRNA, using cultured cell-basis analysis and found that only c.143-83A>G produced transcripts similar to the mice model. Our report is the first to show that the c.143-83A>G variant leads to splicing disruption and causes morphological and functional abnormalities in the pituitary gland. Furthermore, our mice will contribute understanding the role of POU1F1/Pou1f1 transcripts in pituitary development.

Fluorodeoxyglucose-positron emission tomography as a potential alternative tool for functional diagnosis of glycogen storage disease type I

Sato T., Inokuchi M., Nakano S., Iwabuchi Y., Hayashida T., Ishii T., Hasegawa T.

Radiology Case Reports 18 ( 1 ) 91 - 93 2023.01

A 43-year-old woman with genetically confirmed glycogen storage disease type Ib was suspected to have left breast cancer. Fluorodeoxyglucose-positron emission tomography showed high fluorodeoxyglucose accumulation in the whole liver as well as left mammary gland. We consider that high fluorodeoxyglucose accumulation in the liver of patients with glycogen storage disease type I is caused by impaired glucose-6-phosphate metabolism due to the congenital deficiency of glucose-6-phosphatase activities in hepatocytes. This study describes fluorodeoxyglucose-positron emission tomography as a potential alternative tool to diagnose glycogen storage disease type I functionally.

Pallister–Hall syndrome (PHS) is defined as a group of characteristic manifestations caused by a monoallelic GLI3 pathogenic variant. A two-month-old infant was referred to our institution because of undetermined sex. The infant had atypical genitalia with postaxial polysyndactyly, a hypothalamic mass, and an imperforate anus. We identified a known pathogenic variant of the GLI3 gene within one week and diagnosed the infant with PHS. The parents assigned the infant as male, considering the 46,XY karyotype, normal testosterone secretion, possible male identity, and the natural history of PHS. In infants with atypical genitalia and other malformations, such as polydactyly, a hypothalamic mass, or an imperforate anus, rapid GLI3 testing may provide information for planning lifelong management, including sex assignment.

Pubertal induction in Turner syndrome without gonadal function: A possibility of earlier, lower-dose estrogen therapy

Hasegawa Y., Hasegawa T., Satoh M., Ikegawa K., Itonaga T., Mitani-Konno M., Kawai M.

Frontiers in Endocrinology 14 2023

Delayed and absent puberty and infertility in Turner syndrome (TS) are caused by primary hypogonadism. A majority of patients with TS who are followed at hospitals during childhood will not experience regular menstruation. In fact, almost all patients with TS need estrogen replacement therapy (ERT) before they are young adults. ERT in TS is administered empirically. However, some practical issues concerning puberty induction in TS require clarification, such as how early to start ERT. The present monograph aims to review current pubertal induction therapies for TS without endogenous estrogen production and suggests a new therapeutic approach using a transdermal estradiol patch that mimics incremental increases in circulating, physiological estradiol. Although evidence supporting this approach is still scarce, pubertal induction with earlier, lower-dose estrogen therapy more closely approximates endogenous estradiol secretion.

Disorders of sex development (DSD) with mild external genital abnormalities may be diagnosed after puberty. Here, we report a case of 46,XY complete gonadal dysgenesis with a novel missense variant in sex-determining region Y (SRY), diagnosed after primary amenorrhea. A 15-yr-old patient presented to our gynecology department with a chief complaint of amenorrhea. The patient was diagnosed with a 46,XY karyotype, and SRY gene positivity. Gonadotropin levels were high, whereas testosterone levels were low. A pelvic magnetic resonance imaging (MRI) revealed a hypoplastic uterus; however, no gonads could be identified. Laparoscopy revealed bilateral streak gonads, fallopian tube-like structures, and the uterus. The gonads were removed based on the risk of gonadal malignancy. Comprehensive genetic analysis of DSD revealed a previously unreported SRY variant, c.271A>T, p.Ser91Cys, and in silico analysis predicted the variant to be pathogenic. The patient was diagnosed with 46,XY complete gonadal dysgenesis with a novel missense variant in SRY. The patient continued female hormone replacement therapy and experienced breast enlargement and cyclic menstruation. Determining the etiology of DSD can be difficult, causing anxiety in patients and their families. In addition to surgical scrutiny, genetic analysis is important to aid in diagnosis and reassure patients and their families.

Less-invasive diagnostic approaches for low-birthweight preterm neonates with suspected differences of sex development have not been established. Herein, we describe our diagnostic approaches for a 297-g neonate with ambiguous genitalia. Using a fiberscope, the external genitalia were inspected in an incubator to minimize the risk of hypothermia and infection. Endotracheal aspirate, collected during routine care, was used for genetic testing to avoid anemia and vital signs fluctuations caused by peripheral blood sampling. Array comparative genomic hybridization indicated a 46,XY karyotype. No pathogenic variants of AR and SRD5A2 were found. Endocrinological data could not be evaluated owing to the absence of reference data. Identification and structural evaluation of the internal genitalia and gonads were difficult. On postnatal day 42, the parents assigned their baby's sex as male. Our less-invasive diagnostic approaches of inspection and genetic testing are useful for management, including sex assignment in extremely low-birthweight preterm neonates with ambiguous genitalia.

Context: There are limited reports on the detailed examination of steroid profiles for setting algorithms for 21-hydroxylase deficiency (21OHD) screening by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Objective: We aimed to define an algorithm for newborn screening of 21OHD by LC-MS/MS, measuring a total of 2077 dried blood spot samples in Tokyo. Methods: Five steroids (17α-hydroxyprogesterone [17αOHP], 21-deoxycortisol [21DOF], 11-deoxycortisol [11DOF], androstenedione [4AD], and cortisol [F]) were included in the panel of LC-MS/MS. Samples from 2 cohorts were assayed: Cohort A, 63 "screening positive"neonates who were referred to an endocrinologist (n = 26 with 21OHD; n = 37 false-positive; obtained from 2015 to 2020); and Cohort B, samples (n = 2014) with 17αOHP values in the 97th percentile or above, in the first-tier test with 17αOHP ELISA from 2020 to 2021. Results: Analysis of Cohort A revealed that the 3 indexes 21DOF, 11DOF/17αOHP, and (4AD + 17αOHP)/F had higher area under the curve (AUC) values (0.999, 0.997, 0.989, respectively), while the 17αOHP AUC was lower (0.970). Accordingly, in addition to 17αOHP, the 3 markers were included for defining the screening algorithm. The assay of Cohort B revealed that the new algorithm gave 92% of predicted positive predictive value without false-negative cases. We also determined the reference values for the 5 steroids at 4 to 7 days after birth, according to sex and gestational age (GA), revealing extremely low levels of 21DOF at any GA irrespective of sex differences. Conclusion: Our study demonstrated the high relevance of 21DOF, (4AD + 17αOHP)/F, and 11DOF/17αOHP, rather than 17αOHP, for 21OHD screening.

Congenital hypothyroidism due to thyroid dysgenesis (TD), presented as thyroid aplasia, hypoplasia or ectopia, is one of the most prevalent rare diseases with an isolated organ malformation. The pathogenesis of TD is largely unknown, although a genetic predisposition has been suggested. We performed a genome-wide association study (GWAS) with 142 Japanese TD cases and 8380 controls and found a significant locus at 2q33.3 (top single nucleotide polymorphism, rs9789446: P = 4.4 × 10-12), which was replicated in a German patient cohort (P = 0.0056). A subgroup analysis showed that rs9789446 confers a risk for thyroid aplasia (per allele odds ratio = 3.17) and ectopia (3.12) but not for hypoplasia. Comprehensive epigenomic characterization of the 72-kb disease-associated region revealed that it was enriched for active enhancer signatures in human thyroid. Analysis of chromosome conformation capture data showed long-range chromatin interactions of this region with promoters of two genes, FZD5 and CCNYL1, mediating Wnt signaling. Moreover, rs9789446 was found to be a thyroid-specific quantitative trait locus, adding further evidence for a cis-regulatory function of this region in thyroid tissue. Specifically, because the risk rs9789446 allele is associated with increased thyroidal expression of FDZ5 and CCNYL1 and given the recent demonstration of perturbed early thyroid development following overactivation of Wnt signaling in zebrafish embryos, an enhanced Wnt signaling in risk allele carriers provides a biologically plausible TD mechanism. In conclusion, our work found the first risk locus for TD, exemplifying that in rare diseases with relatively low biological complexity, GWAS may provide mechanistic insights even with a small sample size.

ISSN 0334018X

Objectives: The usefulness of continuous glucose monitoring (CGM) in infants with panhypopituitarism (PH) having hypoglycemia is yet to be explored. The potential adverse effects of growth hormone (GH) replacement therapy, such as hyperglycemia, cannot be comprehensively evaluated using the conventional measurement. Case presentation: A 2-month-old infant with PH, including severe GH deficiency, had hypoglycemia despite frequent feeding. Glucose levels were monitored using CGM before and after GH replacement therapy. The proportion of time for hypoglycemia decreased from 4.9 to 0% (p<0.017). Hyperglycemia did not increase. The CGM method did not contribute to any adverse events requiring intervention. Our patient only experienced minor bleeding and no episode of cellulitis. Conclusions: CGM is useful in controlling glucose levels in infants with hypoglycemia and PH.

Recently, whole-exome sequencing (WES) has been used for genetic diagnoses of patients who remain otherwise undiagnosed. WES was performed in 177 Japanese patients with undiagnosed conditions who were referred to the Tokai regional branch of the Initiative on Rare and Undiagnosed Diseases (IRUD) (TOKAI-IRUD). This study included only patients who had not previously received genome-wide testing. Review meetings with specialists in various medical fields were held to evaluate the genetic diagnosis in each case, which was based on the guidelines of the American College of Medical Genetics and Genomics. WES identified diagnostic single-nucleotide variants in 66 patients and copy number variants (CNVs) in 11 patients. Additionally, a patient was diagnosed with Angelman syndrome with a complex clinical phenotype upon detection of a paternally derived uniparental disomy (UPD) [upd(15)pat] wherein the patient carried a homozygous DUOX2 p.E520D variant in the UPD region. Functional analysis confirmed that this DUOX2 variant was a loss-of-function missense substitution and the primary cause of congenital hypothyroidism. A significantly higher proportion of genetic diagnoses was achieved compared to previous reports (44%, 78/177 vs. 24–35%, respectively), probably due to detailed discussions and the higher rate of CNV detection.

An elderly patient with 17α-hydroxylase deficiency misdiagnosed as primary aldosteronism: a case report

Ishinoda Y., Uto A., Yamada Y., Okazaki M., Asada H., Wakamatsu S., Kurihara I., Shibata H., Ishii T., Hasegawa T., Kumagai H., Kasuga A.

BMC Endocrine Disorders 22 ( 1 ) 2022.12

Background: 17α-hydroxylase deficiency (17OHD) is a rare autosomal recessive disorder. Aldosterone levels are usually low in patients with 17OHD. However, among the approximately 150 cases of 17OHD reported to date, aldosterone levels were not low in all cases. Therefore, some 17OHD cases may have been misdiagnosed as primary aldosteronism (PA) cases. Often before puberty, 17OHD is diagnosed because of abnormal genital morphology and menstrual irregularities. However, we report a very rare case of 17OHD in an elderly patient with a high aldosterone/renin ratio (ARR) similar to that in PA. Case presentation: A 63-year-old Japanese woman was transferred to our medical facility for the evaluation of bilateral adrenal hypertrophy, which was incidentally discovered during an abdominal examination after cholecystectomy. The patient had hypokalemia and a high aldosterone/renin ratio. Her medical history included hypertension and right intracerebral capsular hemorrhage at the age of 30 years. Additional testing revealed low cortisol, high adrenocorticotropic hormone, and low testosterone and dehydroepiandrosterone sulfate, indicating congenital adrenal hyperplasia. Genetic analysis revealed a mutation in the CYP17A1 gene and a karyotype of 46, XY; hence, she was diagnosed with 17OHD. Conclusion: 17OHD can resemble PA. The combination of a high ARR and low cortisol level should trigger the consideration of 17OHD.

Introduction: Little is known about the association between hypospadias and small fetuses, as well as the pathological implications of fetal growth restriction (FGR). Thus, we aimed to investigate the association between hypospadias and small fetuses using a database of fetal ultrasound and obstetric events. Methods: A cohort of male singleton infants delivered after 22 weeks of gestation at Keio University Hospital between 2013 and 2019 was retrospectively reviewed. FGR was defined according to the Delphi criteria. Logistic regression analysis was performed to identify the significant predictors of hypospadias. Placental pathology was reviewed in cases with hypospadias. Results: Of the 2,040 male infants included in the present study, 23 had hypospadias. The prevalences of a single umbilical artery (SUA), small for gestational age, maternal hypertensive disorders of pregnancy, and a small placenta, were significantly higher in infants with hypospadias. Multiple logistic regression analysis revealed that FGR (odds ratio [OR] = 9.39; 95% confidence interval [CI], 2.50–35.3) and the presence of a SUA (OR = 33.4; 95% CI, 8.00–139.5) were independently and significantly associated with hypospadias. When FGR was stratified by the time of onset, its association with hypospadias was significant regardless of the time of onset. Moreover, placental histological findings suggested that fetal vascular malperfusion might play a role in hypospadias. Discussion: FGR and SUAs are independent prenatal predictors of the development of hypospadias, and fetal vascular malperfusion of the placenta may be involved in the etiology of hypospadias.

Aim: During the coronavirus disease 2019 pandemic, the governments of many countries responded to high levels of infection with lockdowns. As a result, some children were reported to experience weight gain. The aim of the present study was to examine the impact of school closures on body mass index (BMI) in Japanese children. Methods: This was a retrospective study of students enrolled in the participating schools (6- to 11-year-old elementary school students and 12- to 14-year-old junior high school students) between 2015 and 2020. Using school health check-up data, annual changes in the BMI standard deviation score (ΔBMI-SDS) were calculated. We compared ΔBMI-SDS in 2019–2020 with the corresponding control years. Results: 19 565 children with complete data were included in the analysis. Median ΔBMI-SDS in 2019–2020 were 0.24–0.35 in elementary school boys, 0.10–0.13 in junior high school boys, −0.02 to 0.15 in elementary school girls and −0.14 to −0.10 in junior high school girls. In comparison with every control year, ΔBMI-SDS in 2019–2020 were significantly higher in elementary school boys (control years: −0.07 to 0.14) and junior high school boys (control years: −0.04 to 0.06), and significantly lower in junior high school girls (control years: −0.06 to 0.09). Conclusion: BMI-SDS increased significantly in elementary and junior high school boys, but decreased significantly in junior high school girls. The pandemic appears to have had an impact on Japanese children that was different from other countries.

PAX8 is a transcription factor that is expressed in the thyroid gland and kidneys. Monoallelic loss-of-function PAX8 variants cause congenital hypothyroidism (CH), and urogenital malformations are infrequent complications seen in less than 10% of PAX8 variant carriers. Herein, we report the case of a 3-yr-old female patient with CH who was diagnosed during newborn screening. She was treated with levothyroxine, and she showed normal growth and development at a minimal dose (0.7 µg/kg/d of levothyroxine at 3 yr of age). At 5 mo of age, she visited an emergency department for fever and was incidentally found to have differently sized kidneys by ultrasonography, which was subsequently diagnosed as unilateral multicystic dysplastic kidney. Her serum creatinine and cystatin C levels were normal. Next-generation sequencing-based genetic analysis revealed that the patient was heterozygous for a PAX8 frameshift variant (p.Thr320ProfsTer106) and a DUOX2 missense variant (p.Arg885Gln). Our patient is the first truncating PAX8 variant carrier to have a urogenital malformation with CH. Genetic analysis for PAX8 should be considered in patients with CH and urogenital malformations.

Endocrines 3 ( 3 ) 428 - 432 2022.09

Hypochondroplasia is an autosomal dominant genetic disorder due to a heterozygous pathogenic variant of the FGFR3 gene. The early diagnosis of hypochondroplasia is necessary, since growth hormone is effective for improving adult height. The genetic test for the FGFR3 gene could help the early diagnosis. The detailed characteristics of FGFR3 genotypes have not been widely investigated in Japan, except for a common pathogenic variant, p.Asn540Lys. This study retrospectively analyzed the FGFR3 genotypes of 35 patients from 30 families with hypochondroplasia (age, range 0–6 years, median 1 year) in Japan. The pathogenic variants of FGFR3 were identified in all the patients: p.Asn540Lys in 23 probands (76.7%), p.Lys650Gln in 2 (6.7%), p.Leu324His in 2 (6.7%), p.Leu324Val, p.Ser351Cys, and p.Lys650Thr in 1 each (3.2%). The median age at diagnosis, height SD score at diagnosis, or the severity of radiologic findings was not significantly different between probands with p.Asn540Lys and those with other variants. Intellectual disability or epilepsy was identified in seven patients with p.Asn540Lys, but none with other variants. The genetic test of FGFR3 can be useful for assessing the potential risk of neurological sequela in children with hypochondroplasia.

For salt-wasting 21-hydroxylase deficiency (21OHD), fludrocortisone (FC) is usually supplemented at 0.05–0.2 mg/d dose. To date, no report has described 21OHD neonates requiring > 0.4 mg/d of FC. Our female 21OHD patient was lethargic and experienced weight loss with hyponatremia (133 mEq/L), hyperkalemia (6.5 mEq/L), and elevated active renin concentration (ARC, 1942.2 pg/mL) at 6 days of life. Hydrocortisone and FC replacement were initiated. FC dose was gradually increased to 0.4 mg/d at 21 days of life, but her hyperkalemia (6.4 mEq/L) and high ARC (372.3 pg/mL) persisted. We increased FC to 0.6 mg/d and used a low-potassium and high-sodium formula. Hyperkalemia subsequently improved. At 33 days of life, the ARC decreased to 0.6 pg/mL and FC dosage was gradually decreased. At 3 months of age, the low-potassium and high-sodium formula was discontinued, but the serum potassium level was normal and ARC remained low at 0.1 mg/d of FC. We speculated that severe mineralocorticoid resistance was the reason why her hyperkalemia persisted even with 0.4 mg/d of FC; however, the pathophysiology of transiently severe resistance to FC in this patient is unknown. In conclusion, 21OHD neonates may show severe salt-wasting that transiently require > 0.4 mg/d of FC.

Iatrogenic Cushing syndrome (ICS) may be caused by exposure to corticosteroid therapy. We report a case of ICS caused by topical corticosteroids applied to the skin after skin graft surgery. We presume that the development of ICS, in this case, was attributed to a combination of skin barrier disruption, usage of high-potency corticosteroids, broad application area/ large quantity of the corticosteroid, and the extended treatment period. Patients may be at risk for ICS after extensive skin graft surgery if large amounts of very potent topical corticosteroids are applied for an extended period to prevent scar formation or relieve itching.

Background: Large datasets of detailed anthropometric measurements are scarce in children. The Japanese Standard Association 1978–1981 survey provides a rare opportunity to use high quality data from Japanese children. Aim: To construct inside leg length (ILL) and inside leg length to stature ratio (ILL/S) reference centile curves for Japanese children. Subjects and methods: The study sample consisted of 14,825 boys and 14,577 girls age 0–18 years for stature and weight measurements, and 9064 boys and 8796 girls age 0–12 years for ILL measurements, who participated in the 1978–1981 national survey on body sizes. LMS method was used to construct the reference centile curves. The reference centile curves for stature, weight, ILL, and ILL/S were compared to those of British children. Results: The L, M, and S reference values for Japanese children are presented for stature, weight, ILL, and ILL/S. Compared with British children of 0–12 years of age, Japanese children of 0–12 years of age had shorter median stature, shorter median ILL, and shorter median ILL/S. Conclusion: We present the first reference values for ILL and ILL/S in Japanese children. Japanese children had relatively shorter legs compared to British children from infancy.

Primary aldosteronism (PA) is associated with higher cardiovascular morbidity and mortality rates than essential hypertension. The Japan Endocrine Society (JES) has developed an updated guideline for PA, based on the evidence, especially from Japan. We should preferentially screen hypertensive patients with a high prevalence of PA with aldosterone to renin ratio ≥200 and plasma aldosterone concentrations (PAC) ≥60 pg/mL as a cut-off of positive results. While we should confirm excess aldosterone secretion by one positive confirmatory test, we could bypass patients with typical PA findings. Since PAC became lower due to a change in assay methods from radioimmunoassay to chemiluminescent enzyme immunoassay, borderline ranges were set for screening and confirmatory tests and provisionally designated as positive. We recommend individualized medicine for those in the borderline range for the next step. We recommend evaluating cortisol co-secretion in patients with adrenal macroadenomas. Although we recommend adrenal venous sampling for lateralization before adrenalectomy, we should carefully select patients rather than all patients, and we suggest bypassing in young patients with typical PA findings. A selectivity index ≥5 and a lateralization index >4 after adrenocorticotropic hormone stimulation defines successful catheterization and unilateral subtype diagnosis. We recommend adrenalectomy for unilateral PA and mineralocorticoid receptor antagonists for bilateral PA. Systematic as well as individualized clinical practice is always warranted. This JES guideline 2021 provides updated rational evidence and recommendations for the clinical practice of PA, leading to improved quality of the clinical practice of hypertension.

Growth hormone (GH) deficiency (GHD) in children is a heterogeneous condition that includes several entities of various severities. GH treatment has been affected by various factors. Because comprehensive analyses for Japanese children with GHD over time are scarce, we investigated the baseline characteristics of patients with GHD at the start of GH treatment between 1996 and 2015 using data from the Foundation for Growth Science in Japan. During the registration period, 19,717 subjects were determined to be eligible for GH treatment as GHD. Overall analyses revealed that there were twice the number of male patients as female patients, and the etiology was idiopathic in 91.1%, central nervous system (CNS) tumor at the hypothalamus–pituitary area in 1.7%, CNS tumor distant from the hypothalamus–pituitary area in 0.68%, other tumors in 0.91%, congenital CNS malformations in 0.83%, and other diseases in 1.1% with their specific characteristics. The latest average age, height standard deviation score (SDS), insulin-like growth factor–1 SDS, and proportion of severe GHD at GH treatment initiation were 8.8 years, –2.76, –1.42, and 19.5%, respectively. The proportions of breech delivery and asphyxia gradually decreased, whereas that of caesarean section gradually increased during the registration period with the latest values of 2.2%, 4.9%, and 14.0%, respectively (all analyses: p < 0.0001). In contrast, the proportion of idiopathic GHD with breech delivery seemed to reach the lowest level among those with a birth year before 2000. This study identified the characteristics and changes of patients with GHD over 20 years.

To manage of 21-hydroxylase deficiency (21-OHD), transition medicine from pediatric to adult health care is an important process and requires individually optimized approaches. We sent cross-sectional questionnaire surveys on the current status of transition from pediatric to adult health care in 21-OHD patients to all councillors of the Japanese Society for Pediatric Endocrinology. Many pediatric departments (42.2%) experienced adult 21-OHD patients, and 115 patients (53 males, mean age of 26) in 46 institutions were identified. Whereas almost two-thirds of pediatric endocrinologists regarded the problems of counterparts and cooperation as hindrance of transition medicine, the major reason for continuing to be treated in pediatrics was the patient’s own request. The prevalence of long-term complications including obesity, osteoporosis, infertility, menstrual disorder, gender dysphoria, and testicular adrenal rest tumor were 27.5%, 8.8%, 11.1%, 26.3%, 7.1%, 12.5%, respectively, which is comparable to those of other cohorts previously reported. However, several items, especially infertility and osteoporosis were not checked well enough in adult 21-OHD patients treated in pediatrics. Though 44 of 62 female patients had genital reconstructive surgery, more than half of them were not followed up by gynecologists or pediatric urologists. Quite a few adult 21-OHD patients had been followed up in pediatrics even after coming of age; however, surveillance by pediatric endocrinologists of gynecological, reproductive, and mental problems may be insufficient. Therefore, multidisciplinary approaches should be required in transition medicine for 21-OHD and prerequisite for graduation of pediatrics. Pediatric endocrinologists will need to play a leading role in the development of transition systems.

Biallelic PROKR2 variants and congenital hypogonadotropic hypogonadism: a case report and a literature review

Sugisawa C., Taniyama M., Sato T., Takahashi Y., Hasegawa T., Narumi S.

Endocrine Journal 69 ( 7 ) 831 - 838 2022

ISSN 09188959

Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder that causes gonadotropin-releasing hormone (GnRH) deficiency and sexual immaturity. CHH may accompany an abnormal sense of smell (Kallmann syndrome, KS) or no such manifestation (normosmic-CHH). This unusual combination of manifestations is explained by the fact that GnRH neurons originate in the olfactory placode and migrate to the forebrain during embryogenesis. We describe the case of a 31-year-old man with normosmic-CHH, who also had obesity, type 2 diabetes and intellectual disability. He was noticed to have sexual immaturity (small testes with no pubic hair) at age 20 years, when diabetic ketoacidosis developed. Basal and GnRH-stimulated levels of LH (1.0→12.0 IU/L) and FSH (1.9→6.1 IU/L) were detectable but low. The results of the T&T olfactometer and the Alinamin test were definitely normal, with an anatomically normal olfactory system on MRI. Sequencing of 22 CHH-related genes was performed, and compound heterozygous PROKR2 variants were identified: one was a previously known loss-of-function variant (p.Trp178Ser) and the other was a nonsense variant (p.Trp212*). Through a literature review, we found 22 patients (including our patient) with CHH due to biallelic PROKR2 variants, which led us to recognize that most of the patients (86%) were diagnosed with KS. Clinical observations in this study indicate that, even though they have CHH, biallelic PROKR2 variant carriers may have a normal olfactory system as well as presumably normal migration of GnRH neurons. This suggests that the PROK2-PROKR2 pathway affects the function of GnRH neurons after their migration.

Hereditary paraganglioma presenting with atypical symptoms: Case report

Eguchi S., Ono R., Sato T., Yada K., Umehara N., Narumi S., Ichihashi Y., Nozaki T., Kanomata N., Hasegawa T., Ozawa M., Hasegawa D.

Rationale:Paraganglioma (PGL), an extra-adrenal pheochromocytoma, is a rare tumor, especially in children. While hypersecretion of catecholamines causes the classic triad of headaches, palpitations, and profuse sweating, prompt diagnosis is still challenging.Patient concerns:For 7 months, an 8-year-old boy complained of polyuria and weight loss, followed by proteinuria and headache for 1 month prior to admission. He was admitted to our hospital due to an afebrile seizure.Diagnosis:His blood pressure remained markedly elevated even after cessation of the convulsion. Magnetic resonance imaging of the brain revealed posterior reversible encephalopathy syndrome. Abdominal computed tomography showed a mass lesion encasing the left renal artery, measuring 41 mm in length along its major axis. The plasma and urine levels of normetanephrine were elevated. Additionally, iodine-123-metaiodobenzylguanidine scintigraphy showed an abnormal uptake in the abdominal mass with no evidence of metastasis. Based on these findings, we tentatively diagnosed him with PGL.Intervention:Substantial alpha-and beta-blocking procedures were performed, followed by a tumor resection and an extended left nephrectomy on day 31 of hospitalization. Pathological findings confirmed the diagnosis of PGL.Outcome:The postoperative course was uneventful, and his blood pressure normalized without the use of antihypertensive agents. Genetic testing revealed a known SDHB germline mutation. The same mutation was also detected on his father and paternal grandfather without any history of hypertension or malignant tumor.Lesson:It remains challenging to diagnose pheochromocytoma/paraganglioma (PPGL) promptly because PPGL can present with a variety of symptoms. Preceding symptoms of the presented case might be caused by PGL. Although PPGL is a rare disease, especially in children, it should be considered in differential diagnosis when various unexplained symptoms persist.

Herein, we report two girls with a neonatal screening (NS)-negative 21-hydroxylase deficiency (21-OHD) requiring treatment with hydrocortisone due to virilization that developed in late childhood. Patient 1 was born prematurely on the 30th gestational week with normal external genitalia at birth. She passed the NS for 21-OHD. At 6 yr of age, she was referred to a hospital for evaluation of premature pubarche and clitoromegaly. Her diagnosis was central precocious puberty, and GnRH agonist was initiated. However, her symptoms did not improve despite treatment for over 4 years. She was then referred to our hospital where she was diagnosed with 21-OHD. Although she was started on hydrocortisone therapy, her adult height reached only 140 cm (−3.4 SD). Patient 2 was delivered at 37 weeks of gestation and passed the NS for 21-OHD. She was referred to a hospital because of premature pubarche at the age of 6 yr. She was diagnosed with 21-OHD, and hydrocortisone replacement therapy was initiated. Her present height at 13 yr of age is 148 cm (−1.3 SD). These cases reminded us that the possibility of 21-OHD should be considered when patients show premature pubarche or precocious puberty, even if they passed the NS test for 21-OHD.

SOX9, a transcription factor, is expressed in the undifferentiated XX and XY gonads. SRY induces significant upregulation of SOX9 expression in XY gonads. Loss-of-function SOX9 variants cause testicular dysgenesis in 46,XY patients, while duplication of the total gene or the upstream regulatory region results in testicular development in 46,XX patients. However, gain-of-function (GoF) SOX9 variants have not been reported previously. We report the case of a 16-year-old female patient with a 46,XX karyotype who had masculinized external genitalia and unilateral ovotestis. Next-generation sequencing-based genetic screening for disorders of sex development led to the identification of a novel SOX9 variant (p.Glu50Lys), transmitted from the phenotypically normal father. Expression analysis showed that E50K-SOX9 enhanced transactivation of the luciferase reporter containing the testis enhancer sequence core element compared with that containing the wildtype-SOX9. This GoF activity was not observed in the luciferase reporter containing Amh, the gene for anti-Müllerian hormone. We genetically engineered female mice (Sox9E50K/E50K), and they showed no abnormalities in the external genitalia or ovaries. In conclusion, a novel SOX9 variant with a promoter-specific GoF activity was identified in vitro; however, the disease phenotype was not recapitulated by the mouse model. At present, the association between the GoF SOX9 variant and the ovotestis phenotype remains unclear. Future studies are needed to verify the possible association.

Endocrinology, Diabetes and Metabolism Case Reports 2021 ( 1 ) 2021.04

We report a male infant with congenital nephrogenic diabetes insipidus (NDI) who presented with hypercalcemia and hyperphosphatemia since birth. Serum sodium started to increase at 39 days. Although there was no polyuria, urine osmolality was 71 mOsm/kg, when serum osmolality was 296 mOsm/kg with plasma arginine vasopressin 22.5 pg/mL. He was thus diagnosed as NDI. An undetectable level of urine calcium and unsuppressed intact parathyroid hormone suggested hyperparathyroidism including calcium-sensing receptor mutations that could cause hypercalcemia-induced NDI. Polyuria became apparent after the initiation of i.v. infusion for the treatment of hypernatremia. Low calcium and low sodium formula with hypotonic fluid infusion did not correct hypernatremia, hypercalcemia, or hyperphosphatemia. Hydrochlorothiazide and subsequently added celecoxib effectively decreased urine output and corrected electrolytes abnormalities. Normal serum electrolytes were maintained after the discontinuation of low calcium formula. The genetic analysis revealed a large deletion of the arginine vasopressin receptor-2 (AVPR2) gene but no pathogenic variant in the calcium-sensing receptor (CASR) gene. Whether hypercalcemia and hyperphosphatemia were caused by dehydration alone or in combination with other mechanisms remains to be clarified.

ISSN 0334018X

Background: During 1978-1981 the Japanese Standards Association conducted a national survey to collect 64 distinct body measurements for Japanese children and adults. During 1978-1981, the prevalence of childhood obesity was relatively low yet the population was well nourished in Japanese children. The aim of this study is to construct waist circumference and waist circumference to stature ratio reference centile curves for Japanese preschool children. Methods: We utilized 1978-1981 national survey data on body sizes. There are 4937 boys and 4758 girls age 0-6 years for waist circumference measurements. Waist circumference was measured at the level of the umbilicus. Using LMS method, centile curves were constructed for waist circumference and waist circumference to stature ratio. These reference values were compared with those of Dutch, Swedish and Turkish children. Results: Centile reference curves were made for clinical and epidemiological use. Japanese children had smaller waist circumference centile values as compared to waist circumference measured at the midpoint of the lowest rib cage and the iliac crest of Dutch, Swedish and Turkish children. However, Japanese children had comparable waist circumference to stature ratio centile values to those of Dutch and Turkish children. Conclusions: This study presents the first age-, sex-, and ethnicity-specific reference values for waist circumference and waist circumference to stature ratio in Japanese preschool children.

Objectives: The efficacy of sodium phenylbutyrate (SPB) for hyperammonemia associated with congenital portosystemic shunt (CPSS) remains unknown. We show the effectiveness of oral SPB. Case presentation: Our patient had CPSS with severe hypoplasia of extrahepatic portal veins. At 9 months of age, to assess the efficacy of oral SPB, we evaluated the 24 h fluctuations of venous ammonia levels. In the first two days without SPB, ammonia levels were above 80 μmol/L for half a day. On the third and fourth days, administration of oral SPB three times a day decreased ammonia to acceptable levels, except at midnight. On the fifth day, another oral SPB administration at 8 pm decreased ammonia at midnight. Low levels of branched-chain amino acids, as well as coagulation disturbances, were observed without apparent symptoms. At 12 months of age, he showed normal psychomotor development. Conclusions: Oral SPB may be effective for hyperammonemia associated with CPSS.

ISSN 0021972X

Context: Luscan-Lumish syndrome (LLS) is characterized by postnatal overgrowth, obesity, Chiari I malformation, seizures, and intellectual disability. SET domain-containing protein 2 (SETD2) is a histone methyltransferase, where mutations in the gene are associated with the development of LLS. However, mechanisms underlying LLS remain unclear. Case Description: A 20-year-old man was referred to our hospital because of tall stature. His body height was 188.2 cm (+3.18 SD) and he showed obesity with a body mass index of 28.4 kg/m2. He exhibited acral overgrowth, jaw malocclusion, and prognathism, but no history of seizures, intellectual disability, or speech delay. Serum growth hormone (GH), insulin-like growth factor 1 (IGF-1), and nadir GH levels after administration of 75 g oral glucose were within normal range. Pituitary magnetic resonance imaging showed no pituitary adenoma, but Chiari I malformation. Whole exome sequencing analysis of the proband revealed a de novo heterozygous germline mutation in SETD2 (c.236T>A, p.L79H). Skin fibroblasts derived from the patient grew faster than those from his father and the control subject. In addition, these cells showed enhanced tyrosine phosphorylation and transcriptional activity of signal transducer and activator of transcription 5b (STAT5b) and increased IGF-1 expression induced by GH. Conclusion: This is a mild case of LLS with a novel mutation in SETD2 without neurological symptoms. LLS should be differentiated in a patient with gigantism without pituitary tumors. Although further investigation is necessary, this is the first study to suggest the involvement of aberrant GH signaling in the development of LLS.

Background: One of the major purposes of newborn screening for 21-hydroxylase deficiency (21OHD) is preventing life-threatening adrenal crisis. However, the details of adrenal crisis in newborns are not precisely documented. Aim: We aimed to clarify the clinical details of salt-wasting in newborn 21OHD patients. Methods: Based on the follow-up survey of the screening in Tokyo from 1989 to 2017, we retrospectively analysed the conditions of classical 21OHD neonates before the initiation of therapy. Results: One hundred classical 21OHD patients (55 male, 45 female) were analysed. The age at the first hospital visit was 0–20 days with sex difference (male: 9.0 ± 3.5 days; female: 6.2 ± 3.9 days). Thirty-seven (37.4%) patients exhibited severe salt-wasting (SSW), that is, Na < 130 mEq/L, K > 7 mEq/L or Na/K ratio < 20; except for one case, SSW developed in or after the second week of life. The serum concentrations of Na, K and Na/K were linearly correlated with age in days (R2 =.38,.25, and.34 respectively), suggesting that the risk of SSW increases linearly without a threshold. The age at which the regression lines reached Na < 130 mEq/L, K > 7 mEq/L and Na/K < 20 was approximately coincided, 11.1, 12.3 and 11.2 days, respectively. All SSW patients exhibited decreased body weight from birth in their second week of life. Conclusion: Our data revealed that the risk of developing SSW increases during the second week of life without a threshold, and for preventing SSW, early intervention, ideally during first week of life, is desirable. An increased body weight in the second week of life indicates the absence of SSW.

Frontiers in Pediatrics 8 2021.01

The occurrence of fetuses suspected of having ambiguous genitalia will likely increase in the future. Currently, the impact of prenatal genetic counseling on parents' understanding and psychological preparedness has not been addressed. We provided prenatal genetic counseling to parents of two fetuses suspected of ambiguous genitalia. Case 1: At 22 weeks of gestation, swelling of the labia majora, and a clitoris-like structure were noted despite 46,XY detected in amniotic fluid cells. Case 2: At 28 weeks of gestation, bladder exstrophy and a scrotum-like structure were noted. At 32 weeks (Case 1) and 37 weeks (Case 2) of gestation, we shared information with parents regarding the possible difficulty of legal sex assignment at birth, and a scenario for registration of the birth certificate. At birth, both babies presented with ambiguous genitalia. For both cases, the parents remained calm on seeing their baby's genitalia for the first time. After a month, we shared medical information with parents, including karyotype, testosterone production capacity, and surgical schedule. In both cases parents assigned their respective baby's legal sex as male. Several months later, parents were questioned on prenatal genetic counseling. Case 1: Mother, “I was prepared to address our baby's genitalia calmly.” Father, “I understood the procedure of legal sex assignment.” Case 2: Mother, “Without counseling, I would have been more upset and worried.” Father, “We were assured that multidisciplinary experts would support us.” Prenatal genetic counseling provides reassurance to parents, who remain informed and emotionally secure throughout the legal sex assignment of their child.

Context: Inactivating variants of thyrotropin (thyroid-stimulating hormone; TSH) receptor (TSHR) cause congenital hypothyroidism. More than 60 such variants have been reported so far, most of which were located in the extracellular or transmembrane domain. Objective: We report the identification and characterization of a frameshift TSHR variant in the intracytoplasmic C-tail region. Methods: Sequencing of TSHR was performed in a patient with congenital hypothyroidism. The functionality of the identified variants was assessed by expressing TSHR in HEK293 cells and measuring TSH-dependent activation of the cAMP-response element-luciferase reporter. A series of systematic mutagenesis experiments were performed to characterize the frameshifted amino acid sequence. Results: The proband was heterozygous for a known TSHR variant (p.Arg519His) and a novel frameshift TSHR variant (p.Val711Phefs∗18), which removed 54 C-terminal residues and added a 17-amino acid frameshifted sequence. The loss of function of Val711Phefs∗18-TSHR was confirmed in vitro, but the function of Val711∗-TSHR was found to be normal. Western blotting showed the low protein expression of Val711Phefs∗18-TSHR. Fusion of the frameshift sequence to green fluorescent protein or luciferase induced inactivation of them, indicating that the sequence acted as a degron. A systematic mutagenesis study revealed that the density of hydrophobic residues in the frameshift sequence determined the stability. Eight additional frameshift TSHR variants that covered all possible shifted frames in C-tail were created, and another frameshift variant (Thr748Profs∗27) with similar effect was found. Conclusions: We characterized a naturally occurring frameshift TSHR variant located in C-tail, and provided a unique evidence that hydrophobicity in the C-terminal region of the receptor affects protein stability.

Complete androgen insensitivity syndrome with accelerated onset of puberty due to a sertoli cell tumor

Complete androgen insensitivity syndrome (CAIS) is caused by mutations in the androgen receptor gene. Patients with this syndrome have a 46,XY karyotype, male gonads, and normal female external genitalia. While the pre-pubertal risk of developing gonadal tumors is low in these patients, it increases with age. Most gonadal tumors arise from germ cells; stromal cell tumors are uncommon. Herein, we report a CAIS patient with a feminizing Sertoli cell tumor. The patient presented at 8 yr of age with breast enlargement and growth acceleration, concomitant with elevated serum estradiol levels and suppressed serum gonadotropin levels; these findings were inconsistent with CAIS. The patient underwent gonadectomy at 10 yr of age, and histology demonstrated presence of a non-malignant Sertoli cell tumor in the right gonad. We conclude that this is the first reported case of CAIS with accelerated onset of puberty resulting from a Sertoli cell tumor.

The Career Development for Women Pediatric Endocrinologists and Work-Life Balance Committee and Support Team for Women Doctors in Education and Training Committee investigated the current situation of women doctors in the Japanese Society for Pediatric Endocrinology (JSPE). The proportion of women doctors (PWD) was as follows. 1) Members of JSPE: 40.2% in fiscal 2018, versus 33.3% in fiscal 2010; 2) councilors: 21.6% from fiscal 2014 to 2017, versus 6.3% from fiscal 2008 to 2010; 3) board members: 13.6% from fiscal 2014 to 2017, versus 0% from fiscal 2008 to 2010; 4) board-certified endocrinologists (Pediatrics) and certified endocrine educators (Pediatrics): 31.7% and 25.4% in fiscal 2018, versus 22.4% and 15.3% in fiscal 2010, respectively; and 5) average value of first presenters and chairpersons in the Annual Scientific Meeting of JSPE was 41.4% and 22.3% from 2010 to 2019. These PWD figures for JSPE were higher than those of the Japan Pediatric Society and the Japan Endocrine Society, indicating a reducing gender gap in JSPE, although increases in the PWD of decision-making posts remains insufficient.

ISSN 09188959

Current status and its background of Adult Turner Syndrome (TS) are not clarified well. Via a questionnaire survey of 492 adult women with TS, this study investigated the association between menstruation, Kaufmann therapy (menstrual induction therapy), social status (education, employment & marriage), complications, transition from pediatric to adult care, and sex chromosome karyotype using statistical methods. Spontaneous menarche occurred in 22.0% and more frequently among patients with the 45,X/46,XX karyotype. Over 60% of these subjects, menstruation did not persist regularly. Kauffmann therapy was performed in 69.4%; the most common formulation was a conjugated estrogen and progesterone combination. Marriage and higher education advancement rates were low in adults with TS, whereas their employment rate was similar to that of the age-matched general female population. Patients receiving Kauffmann therapy had higher complication rates, greater education length, and higher employment rates. The higher-education advancement rate was observed among patients with 45,X/46,X,Xi and 46,X,Xi karyotypes. Transition from pediatrician to adult specialist was not smooth, subjects were treated in pediatric departments (60.7%), gynecological department (21.4%), internal medicine departments (13.3%), and others. While reason is not clear, the largest number of TS patients are treated in general pediatrics and the percentage of receiving Kauffmann therapy and having complication were significantly lower than in pediatric and adult department of endocrinology (& metabolism). This Study revealed many novel findings of adult TS.
