Background: Sitosterolemia (STSL) is an extremely rare genetic disease. Xanthomas as the first symptom is frequently misinterpreted as familial hypercholesterolemia (FH) in children. Inappropriate treatment may deteriorate the condition.Objectives: The goal of this study was to summarize the clinical characteristics of children with STSL who had xanthomas as their first symptom and to provide clues for early clinical dia...

Background: The Hedgehog (HH) family plays an important role in the development, proliferation and homeostasis in various tissues and organs. Desert hedgehog(DHH), as a member of this family, is mainly involved in the normal development of testis and the formation of nerve sheath. DHH variation mainly causes 46, XY disorders of sex development (DSD) with or without minifascicular neuropathy(MN). Up to date, only 22 affected patients in detail have bee...

Cerebellar-facial-dental syndrome is a rare autosomal recessive disorder due to biallelic variants in the BRF1 gene. It is characterised by cerebellar hypoplasia, intellectual disability, dysmorphic facial features and short stature. There have been only 12 patients described in the literature to date. We report a case of a 9-year-old non-consanguineous Caucasian boy with cerebellar-facial-dental syndrome and multiple coexisting diagnoses, including Klinefelter syndrome (XXY k...

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...
