Background: MAS is a rare disorder, this syndrome is classically characterized by a triad of physical signs: cafe-au-lait skin pigmentation(SP), fibrous bone dysplasia(FD), peripheral precocious puberty(PPP). In children, the most frequent initial presentation of MAS is PPP. MAS is caused by postzygotic activating mutations at the R201 codon of the GNAS gene, leading to a state of somatic mosaicium. In MAS patients, the frequency of mutations is expected to be...

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...

Background: The combination of Turner syndrome (TS) and congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency is rare. These two diseases affect children’s growth and development through different endocrine hormone metabolic dysfunction.Case presentation: A patient suffering from ambiguous genitalia was referred to our hospital when she was 2 months old. Her length was 58 cm (+0.9 standard deviation, SD) and weigh...

Keywords: Primary ovarian insufficiency; Microsomal maintenance complex 8; Cell apoptosis; Cell cycle; PI3K/AKTBackground: Primary ovarian insufficiency (POI) with a chromosome karyotype of 46,XX in children, compared to adults, is difficult to diagnose and often seek medical attention due to delayed puberty or short stature. We have reported the two novel pathogenic mutations p.C242R and p.S445*of MCM8 gene in a pedigre...

Background: The correlation between free thyroid hormones and poor diabetic control in children with diabetic ketoacidosis (DKA) and the effects of thyroid hormone therapy on euthyroid sick syndrome (ESS) remain unclear.Objective and hypotheses: To investigate characteristics of ESS in children with DKA and the effects of thyroid hormone therapy on ESS. In children with DKA, free thyroid hormones may be associated with the severity of DKA and thyroid hor...

Background and objectives: Dyslipidemia especially hypercholesterolemia attracts much more attention recently. Given different management and treatment of multiple categories, precise diagnosis becomes increasingly important. However, studies in pediatric patients lacks around the world, especially in China. Consequently, this study was designed to confirm the molecular defect of persistent hypercholesterolemia with next-generation sequencing basing on a singl...

Background: Vitamin D-dependent rickets type 3 (VDDR3) is a rare autosomal dominant inheritance disease, which is caused by the gain-of-function mutation in CYP3A4 (c.902T>C p.Ile301Thr).Case Presentation: We report the case of a 32-month-old boy presented with discomfort of both knee-joints, poor mobility, and gait abnormality when running. Laboratory examinations revealed low concentrations of serum calcium, phospho...

Objective: Asprosin, a novel peptide that has recently discovered as an important regulatory adipokine, is relevant to obesity in animals and adult humans. Little is known about its roles in children. The aim of the current study was to determine the potential role of asprosin and explore its relationship to various obesity-related markers in children with obesity.Methods: A cross-sectional study was conducted among 119 ...

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome (IPEX) is caused by mutations in the Forkhead/winged helix transcription factor (FOXP3) gene and is a rare disorder that increasingly has gained attention as a model of genetic autoimmunity. We report two Chinese families with IPEX and the sequencing of the FOXP3 gene.Methods: Two unrelated Chinese cases with IPEX were investigated. In case 1, the proband was a 4 month-y...

Background: Fulminant type 1 diabetes (FT1D) is presented as a severe diabetes subtype among adults, however, we have no idea whether it’s worth being taken seriously among children and adolescents.Objective and hypotheses: We aim to clarify the clinical significance of the subtype. It’s supposed that we may needn’t pay special attention to the subtype.Method: Case–control study design. Data from hospitalized al...
