Background: Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) is caused by a deficiency in GnRH production, secretion or action. IGD is a highly heterogeneous disorder with wide phenotypic spectrum including Kallmann syndrome (KS) with anosmia and normosmic idiopathic hypogonadotropic hypogonadism (nIHH). More than 30 different causative genes have been identified in several studies. However, there are no data on the prevalence, clinical characteristics, and mole...

Background: CHARGE syndrome is a complex of congenital malformations affecting multiple organ systems caused by mutations in CHD7.Objective and hypotheses: This study was performed to evaluate endocrine dysfunctions including hypogonadotropic hypogonadism, growth hormone deficiency, or hypothyroidism in patients with CHARGE syndrome.Method: Eighteen patients (10 males and 8 females) with CHARGE syndrome were included. A di...

Background: Congenital hypothyroidism (CH) is a major target of new born screening. It has two major forms (permanent and transient) that have different prognoses.Objective and hypotheses: The purposes of this study were to assess the trends in incidence of permanent and transient CH in China, and to identify clinical variables that may help to distinguish these two forms of CH.Method: Newborns were screened for CH at Xinhua Hospit...

Background: Despite the importance of hypercholesterolemia in children, it is overlooked, and there are currently few metabolomics-based approaches available to understand its molecular mechanisms.Methods: Children from a birth cohort had their cholesterol levels measured with the aim of identifying the metabolites for the molecular biological pathways of childhood hypercholesterolemia. One hundred and twenty-five childr...

Background: Early timing of puberty is associated with worse cardiometabolic health in adulthood. Furthermore, birth weight (BW) is recognized to have implications for pubertal development and cardiometabolic risk factors. The study aimed to examine the independent association between birth size, dehydroepiandrosterone sulfate (DHEAS) and cardiometabolic risk factors in idiopathic central precocious puberty (ICPP) girls.Methods:<...

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...

We have examined a female child patient aged about 3 years and 8months old to confirm the diagnosis of Schmid metaphyseal chondrodysplasia (SMCD) at the Genetics out-patient department, Children's Hospital Affiliated to Zhengzhou University. The child was diagnosed with the abnormal phenotypic characteristics who showed short-limbed dwarfism, bowed legs, waddling gait and genu varum. Based on the child's family history, during the early stages, the child was misdiagnos...

Case: A 7-year-old female revealed short bowed femurs and humeri with old fractures and bowed tibias and fibulas. Her height was 97cm and weight was 11kg. Her younger sister had the same phenotype as same as her mother. The Trio WES test showed that they all inherited from their mother's COL1A2 gene mutation (c.928G>A; p.G328S) and diagnosed Osteogenesis Imperfecta, type IV. Unfortunately, the 7-year-old girl also presents coarse face, short neck, limi...

Context: Craniopharyngiomas are rare, suprasellar tumours with excellent 5-year survival rates of 95%. Despite their benign histology, their tendency to invade vital nearby optic, hypothalamopituitary and vascular structures, complicates resection whilst potentially causing secondary life limiting morbidity, panhypopituitarism and premature mortality. Since 1997, conservative hypothalamic-sparing surgery and radiation to the residual tumour has replaced aggressive resection at...

Adrenoleukodystrophy (ALD) is an X-linked, metabolic disorder caused by genetic deficiency of peroxisomal ALD protein resulting in accumulation of very-long chain fatty acids (VLCFA) primarily in the adrenal cortex and central nervous system. Approximately 35–40% of boys with ALD develop cerebral ALD (CALD), which causes rapidly progressive cerebral demyelination, loss of neurologic function, and death. Disease progress can be halted by allogeneic hematopoietic cell trans...
