  • Gonadotropin-releasing hormone (GnRH) insensitivity also known as Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) is a rare autosomal recessive genetic and endocrine syndrome which is characterized by inactivating mutations of the gonadotropin-releasing hormone receptor (GnRHR) and thus an insensitivity of the receptor to gonadotropin-releasing hormone (GnRH), resulting in a partial or complete loss of the ability of the gonads to synthesize the sex hormones. (wikipedia.org)
  • Of note, the X-linked form of Kallmann syndrome (KS) form of GnRH insensitivity relating to mutations in the ANOS1 gene has the most consistent severe phenotypic presentation (i.e., prepubertal testes size and complete absence of gonadotropin-releasing hormone [GnRH]-induced luteinizing hormone [LH] pulsations during frequency sampling studies) of all of the genes associated with this condition. (wikipedia.org)
  • citation needed] During childhood, since the hypothalamic GnRH-pituitary-gonadal axis is quiescent, a diagnosis of GnRH insensitivity can generally be heralded only in the presence of nonreproductive phenotypes (e.g., the lack of sense of smell in some patients [anosmia] or skeletal abnormalities, such as cleft lip/cleft palate, hearing deficits, or syndactyly).
