Idiopathic Hypogonadotropic Hypogonadism Caused by Inactivating Mutations in SRA1
OBJECTIVE What initiates the pubertal process in humans and other mammals is still unknown. We hypothesized that gene(s) taking roles in triggering human puberty may be identified by studying a cohort of idiopathic hypogonadotropic hypogonadism (IHH). METHODS A cohort of IHH cases was studied based on autozygosity mapping coupled with whole exome sequencing. RESULTS Our studies revealed thr...
متن کاملStudy on KAL1 Gene Mutations in Idiopathic Hypogonadotropic Hypogonadism Patients with X-Linked Recessive Inheritance
Idiopathic hypogonadotropic hypogonadism (IHH) is a condition caused by low doses of hypothalamic gonadotropin-releasing hormone (GnRH) leading to absence or incomplete sexual maturation. One of the disorders leading to IHH is Kallmann syndrome which is characterized by GnRH deficiency with anosmia or hyposmia. This disorder generally occurs as a hereditary syndrome with X-linked recessive inhe...
متن کاملGonadotropins in Infertile Men with Idiopathic Hypogonadotropic Hypogonadism
Background Stimulatory therapy with gonadotrpins is an effective treatment to induce spermatogenesis in men with idiopathic hypogonadotroptic hypogonadism (IHH). The aim of this study was to assess the effectiveness of human chorionic gonadotropin / human menopausal gonadotropin on hypogonadotropic infertile men. MaterialsAndMethods This study included fifty-six azoospermic infertile men with I...
متن کاملMutations in NR5A1 and PIN1 associated with idiopathic hypogonadotropic hypogonadism.
We tested the hypothesis that mutations in NR5A1 and PIN1 cause disorders in gonadotropin-gonadal system development and function, throught direct DNA sequencing of the coding sequence and splice-sites of NR5A1 and PIN1 in 50 subjects with sporadic idiopathic hypogonadotropic hypogonadism. These patients were recruited from the Pediatrics section of Tongji Hospital, Tongji Medical College, in W...
متن کاملGNRH1 mutations in patients with idiopathic hypogonadotropic hypogonadism.
Idiopathic hypogonadotropic hypogonadism (IHH) is a condition characterized by failure to undergo puberty in the setting of low sex steroids and low gonadotropins. IHH is due to abnormal secretion or action of the master reproductive hormone gonadotropin-releasing hormone (GnRH). Several genes have been found to be mutated in patients with IHH, yet to date no mutations have been identified in t...
