Objective: To explore the genetic basis for a Chinese three-generations pedigree affected with Severe Short Stature with a mild form of Geleophysic Dysplasia Type 2（GD2）Methods: We collected 11 related family members from a Chinese 3-generation pedigree with severe short stature with a mild form of Geleophysic Dysplasia Type 2 GD2. Clinical data of the 11 family members was collected．With genomic DNA...

Background: Tamoxifen is a selective estrogen receptor modulator，administrated in girls with precocious puberty such as McCune-Albright syndrome.Objective: To explore the effect of tamoxifen on the linear growth of precocious pubertal female rats.Method: At 16-22 day of age, 16 precocious pubertal female rats(induced by 300 μg danazol s.c. at 5-day old), were randomized...

Purpose: Identify CYP21A2 gene variants in pediatric patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency from Henan, China, and to analyze genotype-phenotype correlations. We also analyze the relationship between the clinically effective dosage of hydrocortisone and CYP21A2 genotype.Materials/Methods:A total of 214 21-OHD children were recruited in Henan children's hospital from 2008 to 202...

Purpose: The causes of obesity is so much that the pandemic spread the global. The inherited factors have a profound effect on body fat mass, as well as the environmental factors. Out of these, the foremost is genetic factors that tend to early childhood obesity. The consensus recommended that genetic testing is necessary for serious early onset obesity to identify the pathogenic genes of inherited obesity. In order to improve the positive rate of genetic test...

Background: Floating-Harbor Syndrome (FHS) is a rare disorder characterized by facial dysmorphism, short stature, and delayed language development, among other clinical manifestations. In this case-cohort study, we aim ed to evaluate the clinical features and treatment outcomes of ten Chinese children diagnosed with FHS treated with recombinant human growth hormone (rhGH) or nutritional therapy.Methods: In this retrospec...

Objective: To report the clinical characteristics, diagnosis, treatment and genetic analysis of a case of X-linked acrogigantism(X-LAG).Methods: The clinical information of a 4-year-old girl due to “growth acceleration for 2.5 years, breast overflow for 3 months, accompanied by intermittent convulsions twice” was retrospectively reported, and peripheral blood DNA was collected for whole exome sequencing and e...

Background: The Phosphoglucomutase 1 (PGM1) enzyme plays a central role in glucose homeostasis by catalyzing the inter-conversion of glucose 1-phosphate and glucose 6-phosphate. Recently, PGM1 deficiency was recognized to cause the congenital disorders of glycosylation (CDGs). PGM1 deficiency is a rare, autosomal recessive inherited disease which can cause the extreme variability of clinical symptoms multi-organ dysfunction, including ketotic hypoglycemia, dilated cardiomyopat...

Background: Noonan syndrome (NS) is generally considered an autosomal dominant, multisystemic disorder caused by dysregulation of the RAS/mitogen activated protein kinase (MAPK) pathway. The latest research confirmed the existence of a form of Noonan syndrome that is inherited in an autosomal recessive pattern and identify biallelic mutations in LZTR1. In this study, we diagnosed 55 Chinese NS Children via targeted sequencing or whole exome sequencing (TS/WES).<p ...

Objective: To investigate the clinical features and genetic characteristics of HRAS-associated Costello Syndrome.Method: Characteristics of clinical data and gene mutation of two cases Costello Syndrome in XX hospital were retrospectively analyzed. The related literature was searched by using search terms ‘HRAS’ or ‘Costello Syndrome’.Result: Both patients were presented with mental retardation, growth retardati...

Background: Maturity-onset diabetes of the young, type 2 (MODY2), caused by mutations in the glucokinase (GCK) gene is rare in a Chinese population.Objective and hypotheses: We report three Chinese families with MODY2 and sequenced the GCK gene to find novo mutation.Method: Three unrelated Chinese families with MODY2 and pedigrees were investigated. In Family 1, the proband was a 7-year-old girl with impaired fasting glucose (IFG) ...
