Objective: Thyroxine binding globulin (TBG) is the most important thyroid hormone transporter in humans and is encoded by the SERPINA7 gene located on chromosome Xq22.2. By analyzing the genes of TBG-deficient patients, we aim to find a new molecular basis for the possible etiology of the disease.Design and Methods: 10 groups of subjects were enrolled in the pediatric department of the First Affiliated Hospital of Zhejia...

Context: The majority of congenital isolated growth hormone deficiency (IGHD) cases are idiopathic.Recent research has shed light on the genetic aetiologies of congenital hypopituitarism. HESX1 and GLI2 are two transcription factors, amongst a cascade of other transcription factors and signalling molecules, involved in the development of the pituitary gland. Mutations in both genes have been shown to cause congenital hypopituitarism with varying phenotypes.</p...

Background: Spondyloepimetaphyseal dysplasia with joint laxity type 1(SEMD-JL1) is a rare entity with a recessive inheritance. It is one of the genetic skeletal disorders (GSD) and B3GALT6 loss-of-function mutations were found in individuals with SEMD-JL1 from several families. However, there was no case described in China.Case report: An 8-year-old boy presented to our hospital with short stature, hyperlaxity w...

Objective: The aim of this study was to detect potential gene mutation of Methylmalonic acidemia (MAA) in a Chinese patient.Methods: Patient with clinical diagnosis and parents were analyzed in this study. The analysis included medical histories, clinical analysis, and genetic tests. A NGS panel include MUT,MMAA,MMAB,MMADHC and MCEE genes was identify the pathogenic mutation responsible for the MAA and verified by Sanger.Results: A...

Backgroud: Fructose-1,6-bisphosphatase (FBPase) deficiency is a rare autosomal recessive inherited disorder of gluconeogenesis, which caused by the mutations in the FBP1 gene. FBPase deficiency is characterized by recurrent episodes of hypoglycemia with metabolic and lactic acidosis. If diagnosed early, the prognosis of this disorder is excellent by the prevention of hypoglycemia and avoidance of intake of fructose and sucrose. However, the misdiagnosis of FBPase defi...

Background: Short stature can be caused by mutations in a multitude of different genes. Cockayne Syndrome is a rare growth disorder marked by progressive growth failure, neurologic abnormality. The current report describes a patient with severe short stature and neurologic abnormality.Methods: Patient with clinical diagnosis and parents were analyzed in this study. The analysis included medical histories, clinical analysis, and genetic tests. The gene wa...

Background: Accumulated evidence indicates that the GH-IGF-1 pathway might be one of the crucial mechanisms of ISS. Insulin-like growth factor-1 receptor (IGF-1R) is the effector molecule that regulates the cascade reaction of hormone receptors in the GH–IGF-1 axis.Objective and hypotheses: To investigate the role of IGF-1R gene polymorphisms with regard to susceptibility to Idiopathic short stature risk in the Chinese population of Jiangxi area.</p...

Objective: To investigate the clinical and molecular characteristics of a girl with aldosterone synthase deficiency type II (ASDII). We also identified the consequences of a novel splice site mutation in the CYP11B2 gene.Materials and Methods: A4-month-old girl presented with vomiting, diarrhea, and failure to thrive. Her 17α-OHP, cortisol, renin, and aldosterone were all in the normal range, and the ACTH stimulatio...

Objective: To determine the mutation in the SRY gene in a 46,XY complete gonadal dysgenesis patient with bilateral gonadoblastoma and coexisting dysgerminoma. Evaluate the functional consequence of mutated SRY gene in the tumor risk of 46,XY DSD.Methods and Materials: The proband was a 13-year-old girl who was admitted for examination due to undeveloped secondary sexual characteristics. She had no breas...

Objective To study a large Chinese family with Type A Insulin Resistance Syndrome (TAIRS) and the members’ clinical phenotypes. Explore their genotype-phenotype relationship between environmental factors and hereditary features. Methods 19 members of the family were investigated for their past history, dietary habits and living habits. PCR and Sanger sequencing were applied to detect mutations of the INSR gene among 6 core members from the Pedigree. Besides, fasting blood...
