Gene Summary: This gene encodes the receptor for type 1 gonadotropin-releasing hormone. This receptor is a member of the seven-transmembrane, G-protein coupled receptor (GPCR) family. It is expressed on the surface of pituitary gonadotrope cells as well as lymphocytes, breast, ovary, and prostate. Following binding of gonadotropin-releasing hormone, the receptor associates with G-proteins that activate a phosphatidylinositol-calcium second messenger system. Activation of the receptor ultimately causes the release of gonadotropic luteinizing hormone (LH) and follicle stimulating hormone (FSH). Defects in this gene are a cause of hypogonadotropic hypogonadism (HH). Alternative splicing results in multiple transcript variants encoding different isoforms. More than 18 transcription initiation sites in the 5' region and multiple polyA signals in the 3' region have been identified for this gene.

rs104893836 in UBA6-AS1;GNRHR gene and Idiopathic hypogonadotropic hypogonadism PMID 10022417 1999 When expressed in heterologous cells, both Gln106Arg and Ser217Arg mutations altered hormone binding, whereas the Arg262Gln mutation altered activation of phospholipase C. The propositus, a 30-yr-old man, displayed complete idiopathic hypogonadotropic hypogonadism with extremely low plasma levels of gonadotropins, absence of pulsatility of endogenous LH and alpha-subunit, absence of response to GnRH and GnRH agonist (triptorelin), and absence of effect of pulsatile administration of GnRH.
