Case Report:Clinical and genetic features of 46, XY DSD caused by a mutation in DHX37 gene

Yang Yu , Huang Hui , Wu Tieniu , Yang Li

The DHX37 gene has been identified to cause 46, XY disorders of sex development (DSD), yet there are no reports in China. Here, we report a Chinese pediatric case of 46, XY DSD identified by Whole-exome sequencing which carried a heterozygous missense mutation c.2020 C > T (P.R674 W) in DHX37 gene (NM _ 032656) inherited from the mother. Gonadal pathology showed that the left gonad was structured with a vas deferens and epididymal duct, and the right gonad had vas deferens,...

A Novel Mutation of Type I Insulin-like Growth Factor Receptor (IGF1R) Gene in a Severe Short Stature Pedigree Identified by Targeted Next-generation Sequencing (NGS)

Yang Yu , Huang Hui , Li Yang , Xie Liling , Chen Ka , Xiong Ting , Wu Xian

Objective: To identify genetic mutations of a pedigree affected by severe short stature in Chinese populations for the first time.Methods: Auxological and endocrinological profiles were measured. Targeted next-generation sequencing (NGS) analyses comprising 277 shorted stature-associated candidate genes and 19 related copy number variation (CNV) regions were used to identify gene mutations in the proband. Three web-based software programs (SIFT, PolyPhen...

The Role of IGF-1R Gene Polymorphisms with Regard to Susceptibility to Idiopathic Short Stature Risk in the Chinese Population of Jiangxi Area

Yang Yu , Huang Hui , Yu Zhen , Wang Wei , Yang Li , Huang Wei , Xie Liling

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...
