Abstract
49,XXXYY is an extremely rare sex chromosomal aneuploidy (SCA), with only seven cases reported worldwide to date. Among these cases, only three have been documented into adulthood. Moreover, no cases of 49,XXXYY have been reported in Japan. This SCA has been identified in two scenarios: in vitro fertilization and abortion. Similar to 47,XXY, this aneuploidy is a type of Klinefelter syndrome. Aneuploidy of the X chromosome can lead to various progressive complications due to excess X chromosomes. Herein, we present the case of a Japanese man with 49,XXXYY. He exhibited developmental delays and external genitalia abnormalities since early infancy but was not closely monitored for these symptoms until the age of 3 years old. At that time, a chromosome test revealed his karyotype to be 49,XXXYY. Subsequent examinations were conducted due to various symptoms, including delayed motor development, intellectual disability, facial dysmorphisms, forearm deformities, hip dysplasia, cryptorchidism, micropenis, primary hypogonadism, and essential tremor. Since reaching puberty, he has undergone testosterone replacement therapy for primary hypogonadism, experiencing no complications related to androgen deficiency to date. He has maintained normal lipid and glucose metabolism, as well as bone density, for a prolonged period. There are no other reports on the long-term effects of testosterone treatment for the SCA. Appropriate testosterone replacement therapy is recommended for individuals with 49,XXXYY to prevent complications. This report will contribute to an enhanced understanding of the 49,XXXYY phenotype, aiding in the diagnosis, treatment, and genetic counseling of future cases.

Abstract
Achondroplasia (ACH) is a rare, autosomal dominant skeletal dysplasia characterized by short stature, characteristic facial configuration, and trident hands. Before vosoritide approval in Japan, patients with ACH could start growth hormone (GH) treatment at age 3 years. However, ACH and its treatment in young Japanese children have not been studied. This retrospective, longitudinal, medical records-based cohort study (before vosoritide approval) summarized symptoms, complications, monitoring, surgery/interventions, and height with/without GH in Japanese patients with ACH <5 years. Complications were observed in 89.2% of all 37 patients; 75.7% required surgery or intervention. All patients were monitored by magnetic resonance imaging; 73.0% had foramen magnum stenosis, while 54.1% had Achondroplasia Foramen Magnum Score 3 or 4. Of 28 GH-treated patients, 22 initiating at age 3 years were generally taller after 12 months versus 9 non-GH-treated patients. Mean annual growth velocity significantly increased from age 2 to 3 versus 3 to 4 years in GH-treated patients (4.37 vs. 7.23 cm/year; p = 0.0014), but not in non-GH-treated patients (4.94 vs. 4.20 cm/year). The mean height at age 4 years with/without GH was 83.6/79.8 cm. These results improve our understanding of young patients with ACH in Japan and confirm that early diagnosis of ACH and monitoring of complications help facilitate appropriate interventions.

Abstract
Central congenital hypothyroidism (CH) can occur as an isolated deficiency or as part of combined pituitary hormone deficiency. Unlike primary CH, central CH cannot be detected by newborn screening (NBS) using dry filter paper blood TSH levels, and early diagnosis remains challenging. In this study, the clinical and genetic backgrounds of patients with isolated central CH were determined through a questionnaire-based survey among members of the Japanese Society for Pediatric Endocrinology. The known causes of isolated central CH were studied in 14 patients, including six with previously reported patient data. The results revealed IGSF1 and TBL1X pathogenic variants in nine and one patient, respectively. All six patients with low free thyroxine (FT4) levels detected in NBS carried IGSF1 pathogenic variants. Five patients with isolated central CH diagnosed after 3 months of age were variant-negative, except for one female patient with a heterozygous IGSF1 variant. Two of the four variant-negative patients and a variant-positive patient were diagnosed with pituitary hypoplasia. One and two patients with IGSF1 variant had obesity and intellectual disability, respectively. Left amblyopia was identified in the patient with a TBL1X variant. The study revalidated that IGSF1 variants comprise the most frequent pathogenic variant in patients with isolated central CH in Japan. The neonatal period is the optimal time for the diagnosis of central CH, particularly IGSF1 abnormalities, and the introduction of T4 screening should be considered in the future, taking cost-effectiveness into consideration.

Abstract
INTRODUCTION Paget's disease of bone (PDB) is a skeletal disorder characterized by disorganized bone remodeling due to abnormal osteoclasts. Tumor necrosis factor receptor superfamily member 11A (TNFRSF11A) gene encodes the receptor activator of nuclear factor kappa B (RANK), which has a critical role in osteoclast function. There are five types of rare PDB and related osteolytic disorders due to TNFRSF11A tandem duplication variants so far, including familial expansile osteolysis (84dup18), expansile skeletal hyperphosphatasia (84dup15), early-onset familial PDB (77dup27), juvenile PDB (87dup15), and panostotic expansile bone disease (90dup12). MATERIALS AND METHODS We reviewed a Japanese family with PDB, and performed whole-genome sequencing to identify a causative variant. RESULTS This family had bone symptoms, hyperphosphatasia, hearing loss, tooth loss, and ocular manifestations such as angioid streaks or early-onset glaucoma. We identified a novel duplication variant of TNFRSF11A (72dup27). Angioid streaks were recognized in Juvenile Paget's disease due to loss-of-function variants in the gene TNFRSF11B, and thought to be specific for this disease. However, the novel recognition of angioid streaks in our family raised the possibility of occurrence even in bone disorders due to TNFRSF11A duplication variants and the association of RANKL-RANK signal pathway as the pathogenesis. Glaucoma has conversely not been reported in any case of Paget's disease. It is not certain whether glaucoma is coincidental or specific for PDB with 72dup27. CONCLUSION Our new findings might suggest a broad spectrum of phenotypes in bone disorders with TNFRSF11A duplication variants.

Abstract
OBJECTIVE We recently reported cases of adipsic hypernatremia caused by autoantibodies against the subfornical organ in patients with hypothalamic-pituitary lesions. This study aimed to clarify the clinical features of newly identified patients with adipsic hypernatremia whose sera displayed immunoreactivity to the mouse subfornical organ. DESIGN Observational cohort study of patients diagnosed with adipsic hypernatremia in Japan, United States, and Europe. METHODS The study included 22 patients with adipsic hypernatremia but without overt structural changes in the hypothalamic-pituitary region and congenital disease. Antibody response to the mouse subfornical organ was determined using immunohistochemistry. The clinical characteristics were compared between the patients with positive and negative antibody responses. RESULTS Antibody response to the mouse subfornical organ was detected in the sera of 16 patients (72.7%, female/male ratio, 1:1, 12 pediatric and 4 adult patients). The prolactin levels at the time of diagnosis were significantly higher in patients with positive subfornical organ (SFO) immunoreactivity than in those with negative SFO immunoreactivity (58.9 ± 33.5 vs. 22.9 ± 13.9 ng/ml, p < .05). Hypothalamic disorders were found in 37.5% of the patients with positive SFO immunoreactivity. Moreover, six patients were diagnosed with rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation/neural tumor syndrome after the diagnosis of adipsic hypernatremia. Plasma renin activity levels were significantly higher in patients with serum immunoreactivity to the Nax channel. CONCLUSIONS The patients with serum immunoreactivity to the SFO had higher prolactin levels and hypothalamic disorders compared to those without the immunoreactivity. The clinical characteristics of patients with serum immunoreactivity to the subfornical organ included higher prolactin levels and hypothalamic disorders, which were frequently associated with central hypothyroidism and the presence of retroperitoneal tumors.

Abstract
This study aimed to clarify the interannual changes in intimate partner violence against pregnant women after the March 11, 2011 Great East Japan Earthquake in target areas of Miyagi Prefecture that were damaged by the earthquake and tsunami. Because of this disaster, in Miyagi Prefecture, approximately 12,000 people died or went missing, and approximately 238,000 buildings were destroyed. According to the U.S. Geological Survey, the Great East Japan Earthquake is the fourth largest earthquake in the world and the largest in Japan since 1900. The present study was part of the Japan Environment and Children's Study. Data from June 2011 to May 2014 of 79,222 pregnant women were analyzed, calculating the prevalence of physical and mental intimate partner violence in the inland, north coastal, and south coastal areas of Miyagi. These prevalence rates were compared with nationwide rates of intimate partner violence in 2011 using univariate and logistic regression analyses. After the disaster, the incidence of mental intimate partner violence increased in the south coastal area and then improved later (19.4%, 13.1%, and 13.3% for south coastal area, and 13.8%, 13.8%, and 13.1% for nationwide in 2011, 2012, and 2013, respectively). However, in the north coastal area, the incidence of physical intimate partner violence increased after the disaster and then improved later (2.7%, 1.5%, and 1.3% for north coastal area, and 1.4%, 1.3%, and 1.1% for nationwide in 2011, 2012, and 2013, respectively). In the inland area, however, the prevalence of both mental and physical intimate partner violence was consistently higher than nationwide rates after the disaster.

Abstract
INTRODUCTION Measurement of fibroblast growth factor 23 (FGF23) has been reported to be clinically useful for the differential diagnosis of chronic hypophosphatemia. However, assays for research use only are available in Japan. Thus, the objective of this study was to examine the clinical utility of a novel and automated chemiluminescent enzyme immunoassay for the measurement of FGF23. MATERIALS AND METHODS Participants were recruited from July 2015 to January 2017 at six facilities in Japan. Thirty-eight patients with X-linked hypophosphatemic rickets (XLH 15 males, 23 females, age 0-66 years), five patients with tumour-induced osteomalacia (TIO 3 males, 2 females, age 60-73 years), and twenty-two patients with hypophosphatemia (11 males, 11 females, age 1-75 years) caused due to other factors participated in this study. RESULTS With the clinical cut-off value of FGF23 at 30.0 pg/mL indicated in the Diagnostic Guideline of Rickets/Osteomalacia in Japan, the sensitivity and specificity of FGF23-related hypophosphatemic rickets/osteomalacia without vitamin D deficiency (disease group-1) were 100% and 81.8%, respectively, which distinguished it from non-FGF23-related hypophosphatemia (disease group-2). Furthermore, the diagnostic sensitivity of FGF23-related hypophosphatemia with vitamin D deficiency remained at 100%. Among the four patients with FGF23 levels ≥ 30.0 pg/mL in disease group-2, two patients with relatively higher FGF23 values were suspected to have genuine FGF23-related hypophosphatemia, due to the ectopic production of FGF23 in pulmonary and prostate small cell carcinomas. CONCLUSION The novel FGF23 assay tested in this study is useful for the differential diagnosis of hypophosphatemic rickets/osteomalacia in a clinical setting.

Abstract
Cytochrome P450 oxidoreductase deficiency (PORD) is a disorder of steroidogenesis that causes various symptoms such as skeletal malformations, disorders of sex development, and adrenal insufficiency. The aim of this study was to elucidate the clinical characteristics, especially age at diagnosis and treatment, of PORD from the perinatal period to adulthood in Japan. The first questionnaire was sent to 183 council members of the Japanese Society for Pediatric Endocrinology on 1 September 2018. The response rate was 65%, and a total of 39 patients with PORD were examined at 20 hospitals. The second questionnaire was sent in November 2018 to the council members examining these 39 patients with PORD. The response rate was 77%, and we received clinical information on 30 of the 39 patients. The two novel clinical findings were the age at diagnosis and the treatment of Japanese patients with PORD. In many cases, PORD can be diagnosed at <3 months of age. Hydrocortisone as the primary treatment during infancy can be used daily or in stressful situations; however, because patients with PORD generally have mild to moderate adrenal insufficiency, some might be able to avoid hydrocortisone treatment. Patients with PORD should be carefully followed up, and treatment should be optimized as for patients with other types of adrenal insufficiency. Other characteristics in the present study were similar to those described in previous reports.

Abstract
Mechanical stress stimulates bone remodeling, which occurs through bone formation and resorption, resulting in bone adaptation in response to the mechanical stress. Osteocytes perceive mechanical stress loaded to bones and promote bone remodeling through various cellular processes. Osteocyte apoptosis is considered a cellular process to induce bone resorption during mechanical stress-induced bone remodeling, but the underlying molecular mechanisms are not fully understood. Recent studies have demonstrated that neuropeptides play crucial roles in bone metabolism. The neuropeptide, methionine enkephalin (MENK) regulates apoptosis positively and negatively depending on cell type, but the role of MENK in osteocyte apoptosis, followed by bone resorption, in response to mechanical stress is still unknown. Here, we examined the roles and mechanisms of MENK in osteocyte apoptosis induced by compressive force. We loaded compressive force to mouse parietal bones, resulting in a reduction of MENK expression in osteocytes. A neutralizing connective tissue growth factor (CTGF) antibody inhibited the compressive force-induced reduction of MENK. An increase in osteocyte apoptosis in the compressive force-loaded parietal bones was inhibited by MENK administration. Nuclear translocation of NFATc1 in osteocytes in the parietal bones was enhanced by compressive force. INCA-6, which inhibits NFAT translocation into nuclei, suppressed the increase in osteocyte apoptosis in the compressive force-loaded parietal bones. NFATc1-overexpressing MLO-Y4 cells showed increased expression of apoptosis-related genes. MENK administration reduced the nuclear translocation of NFATc1 in osteocytes in the compressive force-loaded parietal bones. Moreover, MENK suppressed Ca2+ influx and calcineurin and calmodulin expression, which are known to induce the nuclear translocation of NFAT in MLO-Y4 cells. In summary, this study shows that osteocytes expressed MENK, whereas the MENK expression was suppressed by compressive force via CTGF signaling. MENK downregulated nuclear translocation of NFATc1 probably by suppressing Ca2+ signaling in osteocytes and consequently inhibiting compressive force-induced osteocyte apoptosis, followed by bone resorption. © 2020 The Authors.

Abstract
Hypophosphatasia (HPP) is a rare bone disease caused by inactivating mutations in the
ALPL gene, which encodes tissue-nonspecific alkaline phosphatase
(TNSALP). Patients with HPP have varied clinical manifestations and are classified based
on the age of onset and severity. Recently, enzyme replacement therapy using bone-targeted
recombinant alkaline phosphatase (ALP) has been developed, leading to improvement in the
prognosis of patients with life-threatening HPP. Considering these recent advances,
clinical practice guidelines have been generated to provide physicians with guides for
standard medical care for HPP and to support their clinical decisions. A task force was
convened for this purpose, and twenty-one clinical questions (CQs) were formulated,
addressing the issues of clinical manifestations and diagnosis (7 CQs) and those of
management and treatment (14 CQs). A systematic literature search was conducted using
PubMed/MEDLINE, and evidence-based recommendations were developed. The guidelines have
been modified according to the evaluations and suggestions from the Clinical Guideline
Committee of The Japanese Society for Pediatric Endocrinology (JSPE) and public comments
obtained from the members of the JSPE and a Japanese HPP patient group, and then approved
by the Board of Councils of the JSPE. We anticipate that the guidelines will be revised
regularly and updated.

Abstract
We evaluated the relationship between preconception folic acid supplementation and the occurrence of neural tube defects (NTDs) in offspring, using data from the Japan Environment and Children's Study (a nationwide prospective birth cohort study) database. Of 92 269 participants with single pregnancies, 74 cases (offspring or fetuses) had NTDs, including 32 cases of spina bifida, 24 cases of anencephaly, and 19 cases of encephalocele. A total of 7634 participants (8.27%) used preconception folic acid supplementation, and of these, 621 (0.67%) also took in dietary folic acid at ≥480 μg/day. Multivariate logistic regression analyses demonstrated no association between preconception folic acid supplementation and NTDs in offspring or fetuses (odds ratio [OR] 0.622; 95% confidence interval [CI]: 0.226-1.713). Moreover, the participants who combined preconception folic acid supplement use with dietary folic acid intake ≥480 μg/day demonstrated no incidence of NTDs in offspring or fetuses. Our analysis is limited by the absence of the data on the daily amount of supplementary folic acid intake, requiring careful attention to the interpretation. Additional surveys are required in Japan to resolve those limitations for further comprehensive assessment.

Abstract
BACKGROUND Some studies have suggested that blastocyst transfer is associated with i) imbalance in the secondary sex ratio (SSR) (which favors male offspring), ii) increased incidence of monozygotic twins (MZT). In contrast, others have not found these changes. In this study, we evaluated the association between blastocyst transfer and SSR and MZT, considering potential parental confounders. METHODS The Japan Environment and Children's Study is a large, nationwide longitudinal birth cohort study funded by the Ministry of the Environment of Japan. We used this large dataset, including 103,099 pregnancies, to further investigate the association between blastocyst transfer, SSR and MZT, using spontaneously conceived pregnancies, non-assisted reproductive technology (non-ART) treatment (intrauterine insemination and ovulation induction with timed intercourse) and cleavage stage embryo transfer for comparison. We evaluated the association with each group, the SSR, and the frequency of MZT, calculating the adjusted odds ratio (AOR) using multivariable logistic regression analyses, adjusting for potential parental confounders such as basic health and socioeconomic status. RESULTS For each group (spontaneous conception vs. non-ART treatment vs. cleavage stage embryo transfer vs. blastocyst transfer), the percentages of males were 51.3% vs 50.7% vs 48.9% vs 53.4% and the monozygotic twinning rates per pregnancy were 0.27% vs 0.11% vs 0.27% vs 0.99% respectively. Multivariate logistic regression analyses indicated that blastocyst transfer was significantly associated with a higher SSR and higher incidence of MZT than the other three groups (SSR: AOR 1.095, 95% CI1.001-1.198; MZT: AOR 4.229, 95% CI 2.614-6.684). CONCLUSIONS There are significant relationships between blastocyst transfer and SSR imbalance and a higher occurrence of MZT.

Abstract
BACKGROUND Dysmenorrhea influences emotional distress as well as physical suffering in young non-pregnant women. The aim of this study was to assess the potential association between preconception dysmenorrhea and the development of psychological distress during pregnancy. METHODS This study was a part of the Japan Environment and Children's Study (JECS), a nationwide birth cohort study conducted between 2011 and 2014 in Japan. A total of 87,102 pregnant Japanese women with no psychological distress (Kessler 6-item psychological distress scale [K6] score ≤ 12) in early pregnancy were eligible. Among these, 7626 had mild and 1638 had severe preconception dysmenorrhea. The prevalence and risk of maternal psychological distress (K6 scores ≥ 13) in the second or third trimester were compared among preconception dysmenorrhea severity groups. RESULTS A higher percentage of women with mild (2.6%) or severe preconception dysmenorrhea (3.6%) suffered psychological distress during pregnancy compared to that in women without dysmenorrhea (2.1%). A multilevel logistic regression model, adjusting for baseline characteristics and the K6 score at enrollment, showed that the severity of dysmenorrhea was associated with psychological distress (mild dysmenorrhea: adjusted odds ratio [aOR], 1.154; 95% confidence interval [95% CI], 0.980-1.359; and severe dysmenorrhea: aOR, 1.457; 95% CI, 1.087-1.951). LIMITATIONS Information about dysmenorrhea was obtained during early pregnancy. The JECS did not have clear diagnostic criteria for dysmenorrhea. CONCLUSIONS Preconception dysmenorrhea is associated with an elevated incidence of psychological distress during pregnancy. Additionally, expectant mothers with a history of severe dysmenorrhea symptoms before pregnancy have a higher risk of developing psychological distress.

Abstract
SRY-negative 46,XX testicular disorders of sex development (DSD) are very rare conditions. Recently, we identified a novel heterozygous NR5A1 mutation, p.Arg92Trp (c.274C>T, p.R92W), in 2 unrelated cases of 46,XX testicular/ovotesticular DSD. We report the clinical course from infancy to puberty in a Japanese male with SRY-negative 46,XX testicular DSD, carrying this p.Arg92Trp mutation in NR5A1. The patient naturally acquired the development of a penis and pubic hair during puberty. However, hypergonadotropic hypogonadism subsequently developed. More clinical cases will be needed to fully understand the effects of the p.Arg92Trp mutation on the ability to maintain testosterone secretion in 46,XX testicular DSD.

Abstract
Smoking during pregnancy is a risk factor for various adverse birth outcomes but lowers the risk of preeclampsia. Cardiovascular adaptations might underlie these associations. We examined the association of maternal smoking with the risk of hypertensive disorders of pregnancy (HDP) in a low-risk population-based cohort of 76,303 pregnant women. This study was a part of the Japan Environment and Children's Study. Smoking status was assessed using questionnaires completed by participants. Information about HDP was assessed using questionnaires completed by doctors. Compared with that for women who did not smoke, women who continued smoking >10 cigarettes per day during pregnancy had a significantly higher risk of developing HDP (odds ratio: 1.58, 95% confidence interval: 1.11-2.25). In multivariate analyses with adjustment for possible confounding factors, the association still remained (odds ratio: 1.51, 95% confidence interval: 1.04-2.19). When we regarded the number of cigarettes as a continuous variable, there was a linear association between the number of cigarettes and risk of HDP, with an odds ratio of 1.02 per cigarette per day (95% confidence interval: 1.00-1.04). Smoking a greater number of cigarettes was associated with a higher risk of HDP after adjustment for possible confounding factors. Cigarette smoking cessation may avoid the complications of HDP. Our findings suggest that, in addition to the risk of small-for-gestational-age children, an increased risk of HDP should be considered in the management of pregnant women who smoke cigarettes.

Abstract
This study examined the association between maternal alcohol consumption during pregnancy and hypertensive disorders of pregnancy in the Japan Environment and Children's Study, a nationwide birth cohort study. A total of 76 940 pregnant women were included in the analysis. Information about alcohol consumption during pregnancy was obtained using two questionnaires: T1 and T2. The mean (standard deviation) gestational age in the T1 and T2 questionnaires were 16.5 (5.8) and 27.9 (3.7) weeks, respectively. Alcohol consumption was considered as an exposure, hypertensive disorders of pregnancy as an outcome, and possible confounding factors were included in a generalized linear mixed-effects model with a logit link function. Among the study subjects, 2 348 (3.1%) women developed hypertensive disorders of pregnancy. Compared with 25 300 women who never drank alcohol, 43 women who drank alcohol according to the T1 questionnaire and continued to drink ≥150 g ethanol/week according to the T2 questionnaire had significantly higher odds of hypertensive disorders of pregnancy. The adjusted odds ratio was 3.98 (95% confidence interval [CI], 1.33-11.9). In conclusion, alcohol consumption of ≥150 g ethanol/week during pregnancy is better avoided because of the high odds of developing hypertensive disorders of pregnancy. It may be meaningful that healthcare providers confirm information about alcohol consumption during pregnancy. Moreover, discontinuation of alcohol consumption is recommended to prevent the onset of hypertensive disorders of pregnancy in Japan.

Abstract
X‐linked hypophosphatemia (XLH) is a disease caused by abnormally elevated FGF23 levels, which cause persistent hypophosphatemia accompanied by subsequent reduction in bone mineralization that presents as rickets or osteomalacia. Burosumab is a fully human monoclonal antibody targeting FGF23 that is under development for the treatment of FGF23‐related hypophosphatemia including XLH. The safety, tolerability, and proof of concept of burosumab have been evaluated in patients with XLH in previous studies conducted in countries outside of Asia. The objective of this study was to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and expression of anti‐drug antibodies in Japanese and Korean adults with XLH. This was a multicenter, sequential dose‐escalation, open‐label, single‐dose study. This study began with cohort 1 (s.c. dose of burosumab 0.3 mg/kg), after which the dose was escalated sequentially in cohort 2 (s.c. dose of burosumab 0.6 mg/kg) and cohort 3 (s.c. dose of burosumab 1.0 mg/kg). The PK of burosumab were linear within the dose range of 0.3 to 1.0 mg/kg. The PD effects such as serum phosphorus concentration, serum 1,25[OH]2D3 concentration, and ratio of tubular maximum reabsorption rate of phosphate to glomerular filtration rate (TmP/GFR) were elevated after a single s.c. administration. The area under the receiver‐operating characteristic curve from 0 to t (AUC0–t) values calculated using the change from baseline values of serum phosphorus, serum 1,25(OH)2D3, and TmP/GFR were correlated with the AUC0–t of burosumab. Furthermore, no serious adverse events (AEs), deaths, remarkable increase or decrease in the corrected calcium or intact PTH levels, or signs of nephrocalcinosis or its worsening were observed after treatment. Some AEs and drug‐related AEs were observed; however, there were no clinically meaningful tendencies. The positive effects and acceptable safety profile seen in this study are encouraging for Japanese and Korean patients with XLH. © 2018 The Authors JBMR Plus published by Wiley Periodicals, Inc. on behalf of American Society for Bone and Mineral Research.

Abstract
Objective: To provide the latest and most promising evidence on the prevalence and determinants for folic acid supplementation in pregnant women in Japan, including differences in prevalence between interview years and determinants across regions.Materials and methods: The study participants were enrolled from 15 regional centers across Japan between January 2011 and March 2014. Information on the use of folic acid supplementation before and during pregnancy and the characteristics of the participants were collected using questionnaires, medical chart reviews, and interviews by research coordinators.Results: Data for 91,538 women who provided sufficient data on folic acid supplementation were analyzed. The prevalence of adequate users was 8.0%, which, although low, tended to improve over the 4-year recruitment period. Various kinds of sociodemographic factors, lifestyle habits, and obstetrical and medication use history were significant and independent determinants for folic acid use. Associations between adequate preconception folic acid use and its major determinants tended to be similar across regions.Conclusions: Although the prevalence of adequate folic acid use was low, it increased from 2011 to 2014. Reproductive-aged women who have determinants for inadequate folic acid use should be informed about the need for preconception folic acid supplementation to help prevent neural tube defects.

Abstract
There is concern that vitamin D deficiency is prevalent among children in Japan as well as worldwide. We conducted a nationwide epidemiologic survey of symptomatic vitamin D deficiency to observe its incidence rate among Japanese children. A questionnaire inquiring the number of new patients with vitamin D deficiency rickets and/or hypocalcemia for 3 years was sent to 855 randomly selected hospitals with a pediatrics department in Japan. In this survey, we found that 250 children were diagnosed with symptomatic vitamin D deficiency. The estimated number of patients with symptomatic vitamin D deficiency per year was 183 (95% confidence interval (CI): 145-222). The overall annual incidence rate among children under 15 years of age was 1.1 per 100,000 population (95% CI: 0.9-1.4). The second survey has provided detailed information on 89 patients with symptomatic vitamin D deficiency under 5 years of age in hospitals in the current research group. The nationwide and second surveys estimated the overall annual incidence rate of symptomatic vitamin D deficiency in children under 5 years of age to be 3.5 (2.7-4.2) per 100,000 population. The second survey revealed 83% had bowed legs, 88% had exclusive breastfeeding, 49% had a restricted and/or unbalanced diet and 31% had insufficient sun exposure among the 89 patients. This is the first nationwide survey on definitive clinical vitamin D deficiency in children in Japan. Elucidating the frequency and characteristics of symptomatic vitamin D deficiency among children is useful to develop preventative public health strategies.

Abstract
Osteogenesis imperfecta (OI) is a heritable disorder characterized by increased bone fragility, low bone mass, dentinogenesis imperfecta, and blue sclerae. Most patients with OI have a mutation in either COL1A1 or COL1A2, which encode type I collagen. We screened these genes in Japanese patients with OI and compared their genotype and phenotype, focusing on the clinical response to treatment with pamidronate. Sequencing analysis of the genes in 19 families revealed 15 mutations, of which ten were missense mutations, thee were nonsense mutations, and two were frameshift mutations. Each of the 15 mutations was found in unrelated families, even though the patients were from a contiguous region surrounding our hospital. Substitutions of serine for glycine were the commonest mutation in both genes; notably, dentinogenesis imperfecta and fractures at birth were detected with higher frequencies in patients with this substitution when compared with other genotypes. The Z score of the bone mineral density of patients with this substitution was also lower than that of patients with other genotypes. Pamidronate treatment significantly increased the Z score in all patients, and increases in the Z score did not correlate with the OI types, causative genes, or genotype. In conclusion, the efficacy of pamidronate treatment does not seem to be related to the genotype of type I collagen in patients with OI.

Abstract
The effects of retinoids on adrenal aldosterone synthase gene (CYP11B2) expression and aldosterone secretion are still unknown. We therefore examined the effects of nuclear retinoid X receptor (RXR) pan-agonist PA024 on CYP11B2 expression, aldosterone secretion and blood pressure, to elucidate its potential as a novel anti-hypertensive drug. We demonstrated that PA024 significantly suppressed angiotensin II (Ang II)-induced CYP11B2 mRNA expression, promoter activity and aldosterone secretion in human adrenocortical H295R cells. Human CYP11B2 promoter functional analyses using its deletion and point mutants indicated that the suppression of CYP11B2 promoter activity by PA024 was in the region from -1521 (full length) to -106 including the NBRE-1 and the Ad5 elements, and the Ad5 element may be mainly involved in the PA024-mediated suppression. PA024 also significantly suppressed the Ang II-induced mRNA expression of transcription factors NURR1 and NGFIB that bind to and activate the Ad5 element. NURR1 overexpression demonstrated that the decrease of NURR1 expression may contribute to the PA024-mediated suppression of CYP11B2 transcription. PA024 also suppressed the Ang II-induced mRNA expression of StAR, HSD3β2 and CYP21A2, a steroidogenic enzyme group involved in aldosterone biosynthesis. Additionally, the PA024-mediated CYP11B2 transcription suppression was shown to be exerted via RXRα. Moreover, the combination of PPARγ agonist pioglitazone and PA024 caused synergistic suppressive effects on CYP11B2 mRNA expression. Finally, PA024 treatment significantly lowered both the systolic and diastolic blood pressure in Tsukuba hypertensive mice (hRN8-12 x hAG2-5). Thus, RXR pan-agonist PA024 may be a candidate anti-hypertensive drugs that acts via the suppression of aldosterone synthesis and secretion.

Abstract
OBJECTIVE Hypophosphatasia (HPP) is a rare skeletal disease characterized by hypomineralization and low alkaline phosphatase activity. Asfotase alfa (AA) has been recently developed to treat HPP complications. This study evaluated its safety and efficacy in Japan. DESIGN Open-label, multicentre, prospective trial. Patients were enrolled in 11 hospitals from June 2014 to July 2015. PATIENTS Thirteen patients (9 females, 4 males) ages 0 days to 34 years at baseline were enrolled and treated with AA (2 mg/kg three times weekly subcutaneously in all but one patient). All had ALPL gene mutations. HPP forms were perinatal (n=6), infantile (n=5), childhood (n=1) and adult (n=1). MEASUREMENTS Safety determined from adverse events (AEs) and laboratory data was the primary outcome measure. Efficacy was assessed as a secondary outcome measure from overall survival, respiratory status, rickets severity and gross motor development. RESULTS Injection site reactions were the most frequent AEs. Serious AEs possibly related to treatment were convulsion and hypocalcaemia observed in a patient with the perinatal form. In addition, hypercalcaemia and/or hyperphosphatemia was observed in three patients with the infantile form and a low-calcium and/or low-phosphate formula was given to these patients. With respect to efficacy, all patients survived and the radiographic findings, developmental milestones and respiratory function improved. CONCLUSION Asfotase alfa therapy improved skeletal, respiratory and physical symptoms with a few serious AEs in patients with HPP. Our results add support to the safety and efficacy of AA therapy for HPP patients.

Abstract
To establish a large-scale isolation procedure for adult porcine islets usable as a donor source for xenotransplantation and as a model of human islet isolation, we improved several characteristics of the conventional isolation procedure. At a slaughterhouse we first selected a breeder pig over 1.5 years old (and over 200 kg in weight) with warm ischemic time (WIT) of 15 ± 2 minutes as nonheart-beating donors. Then, we made a special enzymic mixture that consisted of collagenase S-1 (260 U/mg, NittaZelatin, Japan), collagenase P (1.86 U/ml Lyo Boehringer-Mannheim, USA), DNase (Sigma, St. Louis, Mo), Disparse (NittaZelatin, Japan), and protease inhibitor (Sigma). Third, this mixture was injected very gently into the pancreatic duct at the time of pancreatic harvesting. To prevent overdigestion of the pancreas, the mixture was first cooled to less than 10°C. Fourth, during the warm digestion of pancreas, the pancreas with the enzymic mixture was quietly put in a water bath at 37°C without mechanical shaking. Fifth, we purified the islets with a COBE 2991 cell processor by the Dextran 70 gradient method, because Dextran 70 is very cheap and has the same purification effect as the Ficoll gradient. The results of 10 consecutive breeder porcine islet isolations are reported. The total yield of isolations of islets over 50 μm in the longest diameter after staining with Dithizone (DTZ) was 85,900 ± 19,954 islets, 291,667 ± 240,452 IEQ (2,900 ± 2,324 IEQ/g). The purity of the isolated islets was very high: 90.2 ± 3.8%. Glucose stimulation during in vitro incubation induced significant insulin release from isolated breeder porcine islets. In two of the diabetic rats receiving encapsulated islets grafts using a mesh-reinforced polyvinyl alcohol hydrogel bag (MRPB), a prominent reduction in serum glucose levels (less than 200 mg/dL) persisted for 13 and 19 days, respectively, after intraperitoneal xenotransplantation islets without immunosuppression. In conclusion, we succeeded in a more efficient and less-expensive isolation of a large amount of adult porcine islets from a nonheart-beating donor.

Abstract
We analyzed data from the Japan Environment and Children's Study (JECS), on the association between selective serotonin reuptake inhibitors (SSRI) use during pregnancy and the risk of developing of major congenital anomalies in Japan. JECS is an ongoing nationwide birth cohort study. The study includes 95 994 single pregnant women and their offspring. Among them, 172 used any SSRI up to the 12th gestational week. Crude analyses show a significantly increased incidence of upper limb, abdominal, and urogenital abnormalities. In particular, the incidence of microcephaly, hydrencephalus, esophageal atresia, small intestinal atresia, and achondroplasia was significantly higher with than without exposure to these substances. On multivariate analyses, urogenital abnormality was significant (odds ratio 3.227; 95% confidence interval: 1.460-7.134). This Japanese nationwide birth cohort survey clarified that the use of any SSRI until the 12th gestational week was associated with urogenital abnormality in children. The survey for association with minor classification abnormality needs further examination in Japan.

Abstract
Although existing guidelines recommend long-term follow-up of childhood cancer survivors (CCSs), their fertility has not been fully investigated in Japan. To address this issue, we organized a working panel consisting of medical specialists in foundation hospitals. We conducted questionnaire surveys targeting pediatric endocrinologists regarding reproduction in pediatric and adolescent cancer patients in collaboration with the CCS committee of the Japanese Society for Pediatric Endocrinology (JSPE). The first questionnaire was sent to 178 directors or councilors of the JSPE, and the second was sent to those who had provided answers on their experience with childbirth or fertility preservation. A total of 151 responses (84.8%) were obtained in the first survey. In the second survey, the response rate was 100% (39 respondents). There were 27 answers describing experiences with childbirth (16 from partners of male CCSs, 22 from female CCSs). A few cases of premature birth and low birth weight were reported. There were 25 answers describing experiences with fertility preservation; 21 were from male and 17 from female CCSs. It was mainly physicians who recommended fertility preservation. This nationwide questionnaire survey revealed that a limited number of Japanese pediatric endocrinologists had experience with childbirth and fertility preservation in CCSs. A further long-term follow-up study of their fertility is needed.

Abstract
The Xp22.31 region is characterized by a low frequency of interspersed repeats and a low GC content. Submicroscopic deletions at Xp22.31 involving STS and ANOS1 (alias KAL1) underlie X-linked ichthyosis and Kallmann syndrome, respectively. Of the known microdeletions at Xp22.31, a common approximately 1.5-Mb deletion encompassing STS was ascribed to nonallelic homologous recombination, while 2 ANOS1-containing deletions were attributed to nonhomologous end-joining. However, the genomic bases of other microdeletions within the Xp22.31 region remain to be elucidated. Here, we identified a 2,735,696-bp deletion encompassing STS and ANOS1 in a boy with X-linked ichthyosis and Kallmann syndrome. The breakpoints of the deletion were located within Alu repeats and shared 2-bp microhomology. The fusion junction was not associated with nucleotide stretches, and the breakpoint-flanking regions harbored no palindromes or noncanonical DNA motifs. These results indicate that microhomology-mediated break-induced replication (MMBIR) can cause deletions at Xp22.31, resulting in contiguous gene deletion syndrome. It appears that interspersed repeats without other known rearrangement-inducing DNA features or high GC contents are sufficient to stimulate MMBIR at Xp22.31.

Abstract
BACKGROUND Social capital is generally defined as the quality and frequency of social interactions with relatives, neighbors, and society. Social capital refers to broad concepts of social interactions and structures in individuals, communities and societies such as trust (e.g., neighborhood trust, which is social cohesion with neighbors) and social support (e.g., emotional support, which is the level of the feeling of being loved). Studies during the last few decades have shown that there is a significant inverse association between social capital and the prevalences of diseases such as depression and acute coronary syndrome. Significant inverse associations between trust, social support and the prevalence of diabetes have also been shown. However, associations between social capital and the prevalence of gestational diabetes mellitus (GDM) are less clear. METHODS We used the primary dataset of the Japan Environment and Children's Study (JECS), including 10,228 mothers with recorded obstetric outcomes from January to December 2011. In this study, we included 8874 the 10,228 participants. Diagnosis of GDM was determined using the criteria of the Japan Diabetes Society (JDS). The quality and quantity of social capital were measured with nine questions on a self-administered questionnaire during the second or third trimester. Using principal component analysis (PCA), we distinguished the following three components (indices) of social capital: (A) index of all nine questions about social capital, (B) index of emotional support and neighborhood trust and (C) index of generalized trust. The high factor loading variants of indices were as follows; (A) all nine variants, (B) five variants about emotional support and neighborhood trust and (C) two variants about generalized trust. Multivariate random effect modeling was used to calculate the odd ratios (ORs) for evaluating the association between these indices of social capital and the prevalence of GDM. This model was adjusted for baseline characteristics such as family income, BMI before pregnancy and smoking during pregnancy. RESULTS Of the 8874 participants, 204 women developed GDM (2.30%). Multivariable logistic regression analysis showed that index B, the index of emotional support and neighborhood trust (adjusted OR: 0.651, 95% CI: 0.429, 0.987) was significantly and independently associated with the prevalence of GDM. CONCLUSIONS We found that the 5-question index of emotional support and neighborhood trust is significantly associated with the prevalence of GDM during pregnancy.

Abstract
OBJECTIVE The aim of the study was to clarify the prevalence and determinants of inadequate use of folic acid supplementation in pregnant Japanese women. METHODS This study was part of the Japan Environment and Children's Study, a nationwide and government-funded birth cohort study. We collected information on the use of folic acid supplementation before and during pregnancy and characteristics of participants using self-administered questionnaire. RESULTS Among 9849 women who completed the data collection for this study, the prevalence of inadequate users was 92.6% of the total population and varied from 84.5% to 96.2% among regions. On the basis of multivariate logistic regression analysis, younger age, not married, lower family income, multipara, natural conception and no history of spontaneous abortion were found to be determinants for inadequate users of folic acid supplementation. CONCLUSION Most Japanese pregnant women show inadequate folic acid supplementation use. Japanese women of child-bearing age need to be specifically informed about the need for periconceptional intake of folic acid to prevent neural tube defects.

Abstract
An increasing number of pediatric cancer patients survive, and treatment-related
infertility represents one of the most important issues for these patients. While official
guidelines in Japan recommend long-term follow-up of childhood cancer survivors (CCSs),
their gonadal function and fertility have not been clarified. To address this issue, we
organized a working panel to compile evidence from long-term survivors who received
treatments for cancer during childhood or adolescence. In collaboration with members of
the CCS Committee of the Japanese Society for Pediatric Endocrinology (JSPE), we conducted
a questionnaire survey regarding reproductive function in pediatric cancer patients. A
cross-sectional survey was sent to 178 JSPE-certified councilors who were asked to
self-evaluate the medical examinations they had performed. A total of 151 responses were
obtained, revealing that 143 endocrinologists were involved in the care of CCSs. A quarter
of the respondents reported having experienced issues during gonadal or reproductive
examinations. Several survivors did not remember or fully understand the explanation
regarding gonadal damage, and faced physical and psychological distress when discussing
the risk of becoming infertile. Pediatric endocrinologists had anxieties regarding their
patients’ infertility and the risk of miscarriage, premature birth, and delivery problems.
Only a limited number of endocrinologists had experience with managing childbirth and
fertility preservation. Many councilors mentioned the necessity for inter-disciplinary
communication among healthcare providers. Both endocrinologists and oncologists should set
and follow a uniform clinical guideline that includes management of fertility of CCSs.

Abstract
The etiology of idiopathic short stature (ISS) and Leri-Weill dyschondrosteosis (LWD) in European patients is known to include SHOX mutations and copy-number variations (CNVs) involving SHOX and/or the highly evolutionarily conserved non-coding DNA elements (CNEs) flanking the gene. However, the frequency and types of SHOX abnormalities in non-European patients and the clinical importance of mutations in the CNEs remains to be clarified. Here, we performed systematic molecular analyses of SHOX for 328 Japanese patients with ISS or LWD. SHOX abnormalities accounted for 3.8% of ISS and 50% of LWD cases. CNVs around SHOX were identified in 16 cases, although the ~47 kb deletion frequently reported in European patients was absent in our cases. Probably damaging mutations and benign/silent substitutions were detected in four cases, respectively. Although CNE-linked substitutions were detected in 15 cases, most of them affected poorly conserved nucleotides and were shared by unaffected individuals. These results suggest that the frequency and mutation spectrum of SHOX abnormalities are comparable between Asian and European patients, with the exception of a European-specific downstream deletion. Furthermore, this study highlights the clinical importance and genetic heterogeneity of the SHOX-flanking CNVs, and indicates a limited clinical significance of point mutations in the CNEs.

Abstract
OBJECTIVE To examine psychological distress among pregnant women in Miyagi prefecture which was directly affected by the Great East Japan Earthquake and tsunami and compare other areas of Japan that were less damaged. METHODS This study was conducted in conjunction with the Japan Environment and Children's Study (JECS). We examined 10,129 Japanese women using the primary fixed data of the JECS. The Kessler 6-item psychological distress scale (K6) was administered to 7473 eligible women including 998 in Miyagi unit center ('Miyagi UC') and 6475 in the other unit centers ('13UCs'). We compared the prevalence and the risk of distress (K6 ≥ 13) during pregnancy in 'Miyagi UC' and '13UCs'. RESULTS More women in 'Miyagi UC' (4.9%) suffered psychological distress, compared with '13UCs' (3.1%) (p<0.001). A significantly higher prevalence of women in 'Miyagi UC' (55.5%) had experienced negative life events, whereas '13UCs' showed 42.7% (p<0.0001). In multivariable logistic analyses adjusted for baseline characteristics, there was a significant regional difference of psychological distress (adjusted odds ratio; aOR in Miyagi UC=1.488; 95%CI, 1.059-2.090). After further adjusting for negative life events, the association was diminished (aOR=1.338; 95%CI, 0.949-1.884). LIMITATIONS The JECS had no data before the earthquake and the extent of damage was not investigated. Possible regional representativeness is also a limitation. CONCLUSION After the Great East Japan Earthquake, the prevalence of pregnant women with psychological distress (K6 ≥ 13) were high in Miyagi prefecture. Especially in the coastal area directly affected by tsunami, it is high with or without negative life events experienced.

Abstract
Achondroplasia and Down syndrome are relatively common conditions individually. But co-occurrence of both conditions in the same patient is rare and there have been no reports of fetal analysis of this condition by prenatal sonographic and three-dimensional (3-D) helical computed tomography (CT). Prenatal sonographic findings seen in persons with Down syndrome, such as a thickened nuchal fold, cardiac defects, and echogenic bowel were not found in the patient. A prenatal 3-D helical CT revealed a large head with frontal bossing, metaphyseal flaring of the long bones, and small iliac wings, which suggested achondroplasia. In a case with combination of achondroplasia and Down syndrome, it may be difficult to diagnose the co-occurrence prenatally without typical markers of Down syndrome.

Abstract
Mabry syndrome, hyperphosphatasia mental retardation syndrome (HPMRS), is an autosomal recessive disease characterized by increased serum levels of alkaline phosphatase (ALP), severe developmental delay, intellectual disability, and seizures. Recent studies have revealed mutations in PIGV, PIGW, PIGO, PGAP2, and PGAP3 (genes that encode molecules of the glycosylphosphatidylinositol (GPI)-anchor biosynthesis pathway) in patients with HPMRS. We performed whole-exome sequencing of a patient with severe intellectual disability, distinctive facial appearance, fragile nails, and persistent increased serum levels of ALP. The result revealed a compound heterozygote with a 13-bp deletion in exon 1 (c.36_48del) and a two-base deletion in exon 2 (c.254_255del) in phosphatidylinositol glycan anchor, class L (PIGL) that caused frameshifts resulting in premature terminations. The 13-bp deletion was inherited from the father, and the two-base deletion was inherited from the mother. Expressing c.36_48del or c.254_255del cDNA with an HA-tag at the C- or N-terminus in PIGL-deficient CHO cells only partially restored the surface expression of GPI-anchored proteins (GPI-APs). Nonsynonymous changes or frameshift mutations in PIGL have been identified in patients with CHIME syndrome, a rare autosomal recessive disorder characterized by colobomas, congenital heart defects, early onset migratory ichthyosiform dermatosis, intellectual disability, and ear abnormalities. Our patient did not have colobomas, congenital heart defects, or early onset migratory ichthyosiform dermatosis and hence was diagnosed with HPMRS, and not CHIME syndrome. These results suggest that frameshift mutations that result in premature termination in PIGL cause a phenotype that is consistent with HPMRS.

Abstract
BACKGROUND The prevalence of congenital hypopituitarism (CH) attributable to known transcription factor mutations appears to be rare and other causative genes for CH remain to be identified. Due to the sporadic occurrence of CH, de novo chromosomal rearrangements could be one of the molecular mechanisms participating in its etiology, especially in syndromic cases. OBJECTIVE To identify the role of copy number variations (CNVs) in the etiology of CH and to identify novel genes implicated in CH. SUBJECTS AND METHODS We enrolled 88 (syndromic: 30; non-syndromic: 58) Japanese CH patients. We performed an array comparative genomic hybridization screening in the 30 syndromic CH patients. For all the 88 patients, we analyzed PAX6 by PCR-based sequencing. RESULTS We identified one heterozygous 310-kb deletion of the PAX6 enhancer region in one patient showing isolated GH deficiency (IGHD), cleft palate, and optic disc cupping. We also identified one heterozygous 6.5-Mb deletion encompassing OTX2 in a patient with bilateral anophthalmia and multiple pituitary hormone deficiency. We identified a novel PAX6 mutation, namely p.N116S in one non-syndromic CH patient showing IGHD. The p.N116S PAX6 was associated with an impairment of the transactivation capacities of the PAX6-binding elements. CONCLUSIONS This study showed that heterozygous PAX6 mutations are associated with CH patients. PAX6 mutations may be associated with diverse clinical features ranging from severely impaired ocular and pituitary development to apparently normal phenotype. Overall, this study identified causative CNVs with a possible role in the etiology of CH in <10% of syndromic CH patients.

Abstract
Several studies have described brain white matter abnormalities on magnetic resonance imaging (MRI) in children and adults with congenital adrenal hyperplasia (CAH), while the brain MRI findings of newborn infants with CAH have not been clarified. We report a newborn boy with CAH who presented brain white matter abnormality on MRI. He was diagnosed as having salt-wasting CAH with a high 17-OHP level at neonatal screening and was initially treated with hydrocortisone at 8 days of age. On day 11 after birth, he had a generalized tonic seizure. No evidence of serum electrolyte abnormalities was observed. Brain MRI revealed white matter abnormalities that consisted of bilateral small diffuse hyperintensities on T1-weighted images with slightly low intensity on T2-weighted images in the watershed area. Several factors associated with brain white matter abnormalities in adults with CAH, such as increasing age, hypertension, diabetes and corticosteroid replacement, were not applicable. Although the cause of the phenomenon in this case is unclear, brain white matter abnormality could be observed in newborn infants with CAH as well as in adult patients.

Abstract
ABCC8 encodes the sulfonylurea receptor 1 (SUR1) subunits of the beta-cell ATP-sensitive
potassium (K-ATP) channel playing a critical role in the regulation of insulin secretion, and inactivating
mutations in ABCC8 cause congenital hyperinsulinism. Recently, ABCC8
inactivating mutations were reported to be involved in the development of diabetes mellitus later in life. We
report a girl who was born macrosomic with transient hypoglycemia and thereafter developed diabetes mellitus
accompanied by severe reactive hypoglycemia at the age of 11 yr. An OGTT (oral glucose tolerance test)
revealed hyperglycemia due to poor early insulin response and subsequent hypoglycemia due to delayed prolonged
insulin secretion. Hypoglycemia was improved by the combination of nateglinide, which stimulates early insulin
secretion, and an alpha-glucosidase inhibitor, voglibose. Sequencing of the ABCC8 identified
a compound heterozygous mutation (R1420H/F591fs604X), suggesting that this mutation may alter regulation of
insulin secretion with advancing age, leading to diabetes mellitus with reactive hypoglycemia from
hyperinsulinism. Therefore, long-term follow-up and periodic OGTTs are important for early detection of
insulin dysregulation in congenital hyperinsulinism patients carrying the ABCC8 mutation,
even though hypoglycemia resolves spontaneously during infancy. Furthermore, nateglinide may be useful
therapeutically in the treatment of not only diabetes mellitus but also reactive hypoglycemia.

Abstract
Mutations in NKX2-1 cause neurological, pulmonary, and thyroid hormone impairment. Recently, the disease was named brain-lung-thyroid syndrome. Here, we report three patients with brain-lung-thyroid syndrome. All patients were unable to walk until 24 months of age, and still have a staggering gait, without mental retardation. They have also had choreoathetosis since early infancy. Genetic analysis of NKX2-1 revealed a novel missense mutation (p.Val205Phe) in two patients who were cousins and their maternal families, and a novel 2.6-Mb deletion including NKX2-1 on chromosome 14 in the other patient. Congenital hypothyroidism was not detected on neonatal screening in the patient with the missense mutation, and frequent respiratory infections were observed in the patient with the deletion in NKX2-1. Oral levodopa did not improve the gait disturbance or involuntary movement. The results of (99m)Tc-ECD single-photon emission computed tomography (ECD-SPECT) analyzed using the easy Z-score imaging system showed decreased cerebral blood flow in the bilateral basal ganglia, especially in the caudate nuclei, in all three patients, but no brain magnetic resonance imaging (MRI) abnormalities. These brain nuclear image findings indicate that NKX2-1 haploinsufficiency causes dysfunction of the basal ganglia, especially the caudate nuclei, resulting in choreoathetosis and gait disturbance in this disease.

Abstract
Noonan syndrome (NS) and related disorders are autosomal dominant disorders characterized by heart defects, facial dysmorphism, ectodermal abnormalities, and mental retardation. The dysregulation of the RAS/MAPK pathway appears to be a common molecular pathogenesis of these disorders: mutations in PTPN11, KRAS, and SOS1 have been identified in patients with NS, those in KRAS, BRAF, MAP2K1, and MAP2K2 in patients with CFC syndrome, and those in HRAS mutations in Costello syndrome patients. Recently, mutations in RAF1 have been also identified in patients with NS and two patients with LEOPARD (multiple lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonary stenosis, abnormal genitalia, retardation of growth, and sensorineural deafness) syndrome. In the current study, we identified eight RAF1 mutations in 18 of 119 patients with NS and related conditions without mutations in known genes. We summarized clinical manifestations in patients with RAF1 mutations as well as those in NS patients withPTPN11, SOS1, or KRAS mutations previously reported. Hypertrophic cardiomyopathy and short stature were found to be more frequently observed in patients with RAF1 mutations. Mutations in RAF1 were clustered in the conserved region 2 (CR2) domain, which carries an inhibitory phosphorylation site (serine at position 259; S259). Functional studies revealed that the RAF1 mutants located in the CR2 domain resulted in the decreased phosphorylation of S259, and that mutant RAF1 then dissociated from 14-3-3, leading to a partial ERK activation. Our results suggest that the dephosphorylation of S259 is the primary pathogenic mechanism in the activation of RAF1 mutants located in the CR2 domain as well as of downstream ERK.

Abstract
A range of phenotypes including Greig cephalopolysyndactyly and Pallister-Hall syndromes (GCPS, PHS) are caused by pathogenic mutation of the GLI3 gene. To characterize the clinical variability of GLI3 mutations, we present a subset of a cohort of 174 probands referred for GLI3 analysis. Eighty-one probands with typical GCPS or PHS were previously reported, and we report the remaining 93 probands here. This includes 19 probands (12 mutations) who fulfilled clinical criteria for GCPS or PHS, 48 probands (16 mutations) with features of GCPS or PHS but who did not meet the clinical criteria (sub-GCPS and sub-PHS), 21 probands (6 mutations) with features of PHS or GCPS and oral-facial-digital syndrome, and 5 probands (1 mutation) with nonsyndromic polydactyly. These data support previously identified genotype-phenotype correlations and demonstrate a more variable degree of severity than previously recognized. The finding of GLI3 mutations in patients with features of oral-facial-digital syndrome supports the observation that GLI3 interacts with cilia. We conclude that the phenotypic spectrum of GLI3 mutations is broader than that encompassed by the clinical diagnostic criteria, but the genotype-phenotype correlation persists. Individuals with features of either GCPS or PHS should be screened for mutations in GLI3 even if they do not fulfill clinical criteria.

Abstract
Hypomyelination with hypogonadotropic hypogonadism and hypodontia (4H syndrome) is a rare disease, characterized by both central and peripheral hypomyelination. We describe a 21-year-old male with mildly progressive ataxia, mental retardation, pituitary hypogonadotropic hypogonadism, delayed dentition, and cataract. Brain magnetic resonance imaging showed hypomyelinated white matter, cerebellar atrophy, and a thin corpus callosum. The literature suggests that abnormal findings upon sural nerve biopsy may indicate peripheral hypomyelination, even in the absence of clinically and physiologically evident peripheral neuropathy. A sural nerve biopsy of this patient was normal, and this finding is further discussed. Taken together with previous reports, this case suggests that 4H syndrome can be regarded as a spectrum disorder, the cardinal signs of which may be central hypomyelination, ataxia, hypogonadotropic hypogonadism, and hypodontia.

Abstract
Combined 17alpha-hydroxylase/17,20-lyase deficiency is caused by a defect of P450c17 that catalyzes both 17alpha-hydroxylase and 17,20-lyase reactions in adrenal glands and gonads. In the present study, we analyzed the CYP17A1 gene in a Japanese girl with 17alpha-hydroxylase/17,20-lyase deficiency. The patient was referred to us for clitoromegaly at the age of 3 years. The karyotype was 46,XY. The patient was diagnosed as having 17alpha-hydroxylase/17,20-lyase deficiency based on the clinical and laboratory findings. Analysis of the CYP17A1 gene revealed a compound heterozygous mutation. One mutation was a deletion of codon 53 or 54 encoding Phe (TTC) in exon 1 (DeltaF54) on a maternal allele, which has been previously shown to partially abolish both 17alpha-hydroxylase and 17,20-lyase activities. The other was a novel missense mutation resulting in a substitution of Asn (AAC) for His (CAC) at codon 373 in exon 6 (H373N) on a paternal allele. Functional expression study demonstrated that the H373N mutation almost completely eliminates enzymatic activity. Previous studies have demonstrated that replacement of histidine by leucine at position 373 causes complete loss of both 17alpha-hydroxylase and 17,20-lyase activities with a defect in heme binding due to a global alteration of P450c17 structure, indicating the importance of H373 for P450c17 structure and function. Together, these results indicate that the patient is a compound heterozygote for the DeltaF54 and H383N mutations and that these mutations inactivate both 17alpha-hydroxylase and 17,20-lyase activities and give rise to clinically manifest combined 17alpha-hydroxylase/17,20-lyase deficiency.

Abstract
SummaryThe reaction yields of 63 radionuclides with the mass numberA= 56 − 135 produced in the photofission of209Bi by bremsstrahlung of end-point energies (E0) from 450 to 1100 MeV have been measured using a catcher foil technique with the aid of intensive chemical separation. The charge distribution was well reproduced by a Gaussian function with the most probable charge (Zp) expressed by a linear function ofA,i.e.,Zp=RA+S, and with theA-independent full width at half maximum (FWHMCD). The charge distribution parametersR,Sand FWHMCDwere independent ofE0above 600 MeV, reflecting the resonance nature in photonuclear reactions at intermediate energies. The weighted mean values atE0≥ 600 MeV wereR= 0.421 ± 0.001,S= 0.6 ± 0.1 and FWHMCD= 2.1 ± 0.1 charge unit (c.u.). The numbers of pre- and post-fission neutrons were deduced to be νpre= 12 ± 1 and νpost= 1.4 ± 0.3, respectively, assuming the Unchanged Charge Distribution (UCD). Based on the charge distribution parameters, the symmetric mass yield distributions with the most probable massApof 96 ± 1 mass unit (m.u.) and the width FWHMMDof 33 ± 1 m.u. were also obtained. The characteristics of the charge and mass yield distributions are discussed by referring to those for197Au based on the results of calculations using the Photon-induced Intranuclear Cascade Analysis code combined with the Generalized Evaporation Model (PICA3/GEM).

Yields of7Be,10Be,22Na,24Na and28Mg produced fromnatB,natC,natO,23Na,27Al,natSi,natS,natCl,natK,natCa,natV,55Mn,natFe,59Co,natNi,natCu,89Y,natAg,natIn,141Pr,159Tb,165Ho and197Au in irradiations with bremsstrahlung having maximum end-point energies up to 1200 MeV were measured by γ-ray spectrometry (7Be,22Na,24Na and28Mg) and accelerator mass spectrometry (10Be). The yields of heavier fragments,39Cl,43, 44m, 44g, 46, 47, 48Sc,59Fe, and56, 57, 58, 60Co, were also measured by γ-ray spectrometry in order to survey the relative contribution of fragmentation to spallation and/or fission in the mass yield curves. A distinct difference of the target mass-dependence of these yields has made it possible to disentangle the contributions of photospallation and photofragmentation processes. It was found that the neutron-to-proton ratios of targets strongly affect the formation of the nuclei by fragmentation as revealed in the yields of the isotopic pairs as well as of the single isotopes. The photon results were compared with those of proton-induced reactions, and no clear effect due to the difference of the initial interactions of photons and protons with nuclei was found in the fragment yields.
