Objective: Inactivating mutations in the gene encoding the alpha-subunit of Gs (GNAS) gene, which consists of exons 1-13 and encodes the alpha-subunit of the stimulatory G protein (Gsa), are associated with several clinical syndromes, including pseudohypoparathyroidism (PHP), pseudopseudohypoparathyroidism (PPHP), and progressive osseous heteroplasia (POH).Method: We documented patient clinical characteristics a...

Objective: Through the diagnosis and treatment of Uighur girl with adrenocortical adenoma, who was complain of short stature, to prompt pediatric endocrinologists pay attention to hypercortisolism in the diagnosis and treatment of children with short stature.Methods: With the case report of hypercortisolism in a Uighur child, to introduce the diagnosis and treatment of adrenocortical adenoma, presenting the clinical char...

Background: Pseudohypoparathyroidism type 1b (PHP1b) is caused by epigenetic errors on the maternal GNAS allele at differentially methylated regions (DMRs) associated with exons A/B, XL, and NESP that lead to reduced production of Gαs transcripts most notably in the renal proximal tubule and thyroid follicular cells. Most PHP1b cases appear sporadically, few of which can be explained by paternal uniparental disomy involving chromosome 20q, leading to global methy...

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: Bisphenol A (BPA) is one of high production-volume chemicals and used extensively in consumer products, including food containers and epoxy food-can coatings. The primary source of BPA exposure in adults is via food and beverages, while among infants breast milk and polycarbonate feeding bottles are the predominant source of BPA exposure.Objectives and hypotheses: To estimate the association between serum BPA A and premature thelarche in fema...

Background: Micropenis are the most common signs of incomplete masculinisation, but do not receive enough attention. The etiology is very complex, including endocrine factors, genetic factors and environmental endocrine disruptors.Objective and hypotheses: To explore 45 cases of micropenis children steroidogenesis factor 1 genetic abnormalities and to research the influence of the mutation on sex gland function.Method: 45 micropeni...

Background: Cardiovascular disease is one of the most prominent causes of mortality world widely. A key related factor of atherosclerotic cardiovascular disease is the presence of dyslipidemia. Together with elevated blood pressure, obesity, and diabetes mellitus, dyslipidemia is a component of metabolic syndrome and associated with an increasing incidence of coronary heart disease.Objective and hypotheses: The aim of this study was to investigate the co...

Background: Progressive familial intrahepatic cholestasis (PFIC) is an autosomal recessive diseases.Objective and hypotheses: To explore the characterization of ATP8B1, ABCB11 and ABCB4 gene mutational spectrum in children from South China.Method: By using PCR combined with direct DNA sequencing for 32 patients.Results: Six patients were diagnosed as PFIC.Conclusion: Six novel mutations...

Background: Vitamin D dependent rickets type 1A (VDDR1A) is a rare disease caused by CYP27B1 mutations which encodes vitamin D 1α-hydoxylase.Objective and hypotheses: Vitamin D dependent rickets type 1A features of three Chinese cases with CYP27B1 mutations and report the experience of medication for severe hypocalcaemia.Method: Summarise their clinical features analyse the CYP27B1 and vitamin D receptor (VDDR) mutations.<...

Background: Thyroid carcinoma is the most common endocrine malignancy and most common secondary malignancy for childhood cancer survivors. Radiation exposure has been clearly linked to risk. Thyroid nodules in children have a high risk for malignancy, whether arising spontaneously or after radiation. Reported incidence of thyroid carcinoma after radiation is 20 times the population risk, partly due to improved long-term childhood cancer survival and more active surveillance. D...
