Background: Steroidogenic factor 1 (encoded by the NR5A1gene) is a transcriptional regulator of genes involved in gonadal development and steroidogenesis. Mutations in NR5A1 have been identified among the most frequently genetic causes of disorders of sex development (DSD).Objective: To report the phenotype of 31 patients associated with 17 novel and 9 previously described NR5A1 sequence varian...

Introduction: The PLIN1 gene encodes perilipin - a lipid droplet coat protein expressed in adipocytes where it inhibits basal and facilitates stimulated lipolysis. Mutations in PLIN1 have been described in several families with partial lipodystrophy, dyslipidemia and insulin resistance (partial lipodystrophy type 4, Familial, FPLD4). Herein we describe a novel heterozygous c.1210-1delG splicing variant in PLIN1 gene in three unrelate...

Background: GNRHR gene mutations are responsible for development to normosmic idiopathic hypogonadotropic hypogonadism (iHH) and known to be the most frequent cause of this condition. Nevertherless, the reported frequency of GNRHR mutations in iHH patients estimated to be as low as 3-6%.Objective: To evaluate the frequency of GNRHR gene defects in a heterogeneous group of Russian patients with iHH and described the p...
