Miscellaneous:
phenotypic variability within families and among patients carrying the same mutation appears to be due to the oligogenic nature of the disorder, with some patients having mutations in more than 1 neuroendocrine-related gene

Summaries for Hypogonadotropic Hypogonadism 20 with or Without Anosmia

OMIM : 57 Congenital idiopathic hypogonadotropic hypogonadism (IHH) is a disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. Idiopathic hypogonadotropic hypogonadism can be caused by an isolated defect in gonadotropin-releasing hormone (GNRH; 152760) release, action, or both. Other associated nonreproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss, occur with variable frequency. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism has been called 'Kallmann syndrome (KS),' whereas in the presence of a normal sense of smell, it has been termed 'normosmic idiopathic hypogonadotropic hypogonadism (nIHH)' (summary by Raivio et al., 2007). Because families have been found to segregate both KS and nIHH, the disorder is here referred to as 'hypogonadotropic hypogonadism with or without anosmia (HH).' For a discussion of genetic heterogeneity of hypogonadotropic hypogonadism with or without anosmia as well as a discussion of oligogenicity of this disorder, see 147950. (615270)

MalaCards based summary : Hypogonadotropic Hypogonadism 20 with or Without Anosmia, is also known as hh20. An important gene associated with Hypogonadotropic Hypogonadism 20 with or Without Anosmia is FGF17 (Fibroblast Growth Factor 17). Affiliated tissues include pituitary and olfactory bulb, and related phenotypes are hypogonadism and delayed puberty

Disease Ontology : 12 A hypogonadotropic hypogonadism that has material basis in heterozygous mutation in the FGF17 gene on chromosome 8p21, sometimes in association with mutations in other genes.

UniProtKB/Swiss-Prot : 75 Hypogonadotropic hypogonadism 20 with or without anosmia: A disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. In some cases, it is associated with non- reproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss. Anosmia or hyposmia is related to the absence or hypoplasia of the olfactory bulbs and tracts. Hypogonadism is due to deficiency in gonadotropin-releasing hormone and probably results from a failure of embryonic migration of gonadotropin- releasing hormone-synthesizing neurons. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism is referred to as Kallmann syndrome, whereas in the presence of a normal sense of smell, it has been termed normosmic idiopathic hypogonadotropic hypogonadism (nIHH).
