Chan Li , Huebner Angela , Spoudeas Helen , Cheetham Tim , Metherell Louise

Background: Mutations in the side chain cleavage enzyme, (CYP11A1) cause congenital adrenal insufficiency, with complete or partial 46XY sex reversal. The disorder manifests with adrenal and gonadal insufficiencies along with derangements of the renin/angiotensin system.Objective and hypotheses: To obtain a genetic diagnosis in six patients with adrenal insufficiency of unknown aetiology. Patients 1 and 2 are sisters with ACTH resistance, having...

The genotype-phenotype correlations in patients with 21-hydroxylase deficiency in Henan, China and the relationship between the clinically effective dosage of hydrocortisone and CYP21A2 genotype

Yang Haihua , Wei Haiyan , Huang Ai , Chen Yongxing , Li Yangshiyu

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...

The gene diagnostic challenge of extrem early-onset obesity before 6 years old

Chen Si , Cheng Xinran , Li Zhonghui , Ge Liyuan , Wang Liuxu

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...

Clinical and Molecular Genetic Characterization of Two Patients due to Mutations

Ding Yu , Li Niu , Chang Guoying , Li Juan , Yao Ruen , Shen Yiping , Wang Jian , Huang Xiaodong , Wang Xiumin

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...

Targeted/Exome Sequencing Identified Mutations in 55 Chinese Children Diagnosed with Noonan Syndrome and a Autosomal Recessive form Associated with LZTR1 Variants

Li Xin , Yao Ruen , Chen Yao , Chang Guoying , Ding Yu , Li Juan , Shen Yiping , Wang Xiumin , Wang Jian

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 ...
