Central precocious puberty (CPP) is the endocrine disorder triggering by many factors those can activate the hypothalamic-pituitary-gonadal axis early which controlled GnRH secretion. However, the mechanism of CPP has not been elucidated. The study of patients with familial CPP helped understanding the complex physiological processes. Recently, loss-of-function mutations in human Makorin ring finger protein 3 (MKRN3) were found to contribute to over 30% of cases of familial CP...

Introduction: Alstrom syndrome, inherited in autosomal-recessive manner, is a complex multi-system disease including obesity, sensorineural hearing loss, retinal dystrophy, cardiomyopathy, type 2 diabetes mellitus, and multiple organ fibrosis. ALMS1 is the defective protein of Alstrom syndrome. The protein is located in the basal body of the primary cilia and involved in ciliary function. Large cohorts of Alstrom syndrome lack around the world, especially in E...

An association between Turner syndrome (TS) and Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency is rare. TS is caused by partial or complete loss of the second sexual chromosome which leads to genital system malformation and infertility. 21-hydroxylase deficiency is a well-known cause of disorder of sexual development in genotypic female neonates.The aim of our study is to report this patient and stress this rare possibility. A 8-month-old patient sufferi...

Objective: To observe and analyze the efficacy and safety of autologous stem cell transplantation (AHSCT) in children with type 1 diabetes.Methods: Twelve children were enrolled in our study who were newly diagnosed as type 1 diabetes in Children's Hospital of Fudan University from Sep. 2009 to Dec. 2011. Changes in the exogenous insulin requirement were observed and HbA1C and C peptide level were measured before and...

Background: Partial thyroxine-binding globulin deficiency (TBG-PD) is an endocrine defect with a prevalence of 1:4 000 in newborns. Due to the presence of a single TBG gene on the X chromosome.Objective and hypotheses: To investigate the clinical characteristics of twins with thyroxine binding globulin deficiency and to find SERPINA7 gene mutations.Method: Data related to clinical characteristics, serum biochemistry, gene mutations...

Background: Hypoglycemia triggers the secretion of counter-regulatory hormones such as cortisol, GH, and glucagon, all of which are protective mechanisms to restore euglycemia. It has been suggested that CHI patients have abnormal glucagon secretion during hypoglycemia, but the data is limited.Objective and hypotheses: To investigate the secretion of counter-regulatory hormones including glucagon during hypoglycemia. It’s supposed that these hormone...

A Chinese family of Han with symptoms of matrilineally-inherited obesity was assessed and its clinical, genetic, and molecular profiling was conducted. Obesity was observed in matrilineal relatives (3 out of 14) of a single generation (of 3 alive generations) of this family. On pedigree analysis and sequencing of their mitochondrial DNA, a novel homoplasmic mutation of the mitochondrial tRNAThr gene (15894G>A) was identified in these individuals. This mutation c...

In this study, we conducted a clinical, genetic, and molecular profiling of a Han Chinese family with evident of matrilineally-inherited obesity. Obesity was evident in 2/6 matrilineal relatives in a single generation of this family (of 3 available generations). When the mitochondrial DNA of these individuals was sequences and a pedigree analysis was performed, we were able to identify a novel homoplasmic mutation of the mitochondrial tRNAGly gene (10029A>G) in t...

Background: Mosaic variegated aneuploidy syndrome（MVA）is a rare genetic disease characterized by mosaic aneuploidies, intrauterine growth restriction, developmental delay, microcephaly, facial dysmorphism, mental retardation, and susceptibility to tumor. It is autosomal recessive and caused by mutations in BUB1B, CEP57, and TRIP13. This study hereby presents a 9-year-old girl with intrauterine growth restriction, short stature, microcephaly, faci...

We present two cases of a 13-year-old boy and a 12-year-old girl who were initially diagnosed as central diabetes insipidus (CDI). The Magnetic resonance imaging (MRI) showed pituitary stalk thickening with prominent homogeneous contrast enhancement in T1W and the loss of high signal in the posterior pituitary. In addition to CDI, the two children have a common clinical manifestation of growth retardation, with the laboratory tests suggesting complete growth hormone deficiency...
