Background: Nephrogenic diabetes insipidus (NDI) is a disorder characterized by renal resistance to the antidiuretic effect of AVP. Affected patients are exhibiting symptoms as polyuria and polydipsia. Approximately 90% of congenital NDI are inherited in an X-linked recessive manner and caused by mutations of arginine vasopressin type 2 receptor (AVPR2) gene.Objective and hypotheses: An 8-year-old Japanese boy was referred to our hospital for nocturnal e...

Background: Recently, eight MAP3K1 mutations have been identified in patients with 46,XY disorder of sex development (DSD), although detailed clinical findings of the mutation-positive patients remain to be investigated.Objective and hypotheses: To clarify the frequency and clinical consequences of MAP3K1 mutations.Method: Mutation screening of MAP3K1 were performed for 37 patients with 46,XY DSD. Phenoty...

Background: WDR11 has recently been reported as one of the causative genes of hypogonadotropic hypogonadism (HH). To date, five missense mutations in WDR11 have been identified in six patients with normosmic isolated HH (nIHH) or Kallmann syndrome (KS).Methods: We performed mutation screening of WDR11 for 46 cases with various types of HH. RT-PCR was carried out for a patient with a mutation. The protein structure of the mutant...

Background: The clinical diagnosis of x-linked hypophosphatemic (XLH) rickets is based on a number of biochemical observations. These include a reduction in the percentage of tubular reabsorption of phosphate (%TRP), and in the maximal tubular phosphate reabsorption capacity corrected for glomerular filtration rate (TmP/GFR). However, it is important to maintain sufficient renal blood flow in order to accurately calculate TmP/GFR.Objective: The aims of t...

Background: Patients with homozygous and compound heterozygous familial hypercholesterolemia (FH) have markedly elevated plasma LDL cholesterol (LDL-C) from birth. If untreated, patients develop cardiovascular atherosclerosis resulting in death before the second decade of life. Medication and apheresis are only partially effective in reducing LDL-C levels, and do not significantly improve the prognosis. Liver transplantation (LT) can nearly normalize the cholesterol metabolism...

Background: Haematopoietic stem cell transplantation (HSCT) is a risk factor for young adult onset diabetes mellitus (DM) and hyperlipidaemia (HL) as late effects, especially the use of total-body irradiation (TBI). In order to investigate the clinical details, we retrospectively analysed the post-HSCT patients in our institution that required treatment for DM and/or HL.Results: From 1983 to 2012, 24 children received HSCT in our hospital because of haem...

Background: Late preterm birth (defined as infants born between 34 and 36 weeks of gestational age) is increasing worldwide. Their postnatal growth has not been fully investigated.Objective and hypotheses: To identify the characteristics of postnatal growth and biochemical markers in late preterm infants.Method: Among 2014 children in the birth cohort study conducted from 2010, 51 children were born late preterm with birth weight a...
