The genetic basis of idiopathic hypogonadotropic hypogonadism. The mechanisms that underlie hypogonadotropic hypogonadism involve mutations in many genes. Some of these genes encode proteins that regulate GnRH neuronal migration, other genes encode proteins that regulate GnRH secretion or GnRH action. Abbreviation: GnRH, gonadotropin-releasing hormone.
