LHCGR（luteinizing hormone/choriogonadotropin receptor），癌症关联基因，基因ID：3973，这个基因编码促黄体生成素和绒毛膜促性腺激素的受体该受体属于g蛋白偶联受体1家族，其活性由激活腺苷酸环化酶的g蛋白介导。该基因突变导致男性继发性性征发育障碍，包括家族性男性性早熟，也被称为性腺机能减退、性腺机能减退、性早熟的睾丸间质细胞腺瘤和男性睾丸间质细胞发育不全。[由RefSeq提供，2008年7月]This gene encodes the receptor for both luteinizing hormone and choriogonadotropin. This receptor belongs to the G-protein coupled receptor 1 family， and its activity is mediated by G proteins which activate adenylate cyclase. Mutations in this gene result in disorders of male secondary sexual character development， including familial male precocious puberty， also known as testotoxicosis， hypogonadotropic hypogonadism， Leydig cell adenoma with precocious puberty， and male pseudohermaphtoditism with Leydig cell hypoplasia.
