Genotype and phenotype of patients with gonadotropin-releasing hormone receptor mutations.

Abstract excerpt

Human mutations in the gonadotropin-releasing hormone receptor (GNRHR) gene cause autosomal recessive, normosmic idiopathic hypogonadotropic hypogonadism (IHH). At least 19 different mutations have been identified in this G-protein-coupled receptor, which consist mostly of missense mutations. The Gln106Arg and Arg262Gln mutations comprise nearly half of the identified alleles. Most mutations impair ligand binding...
