A number sign (#) is used with this entry because hypogonadotropic hypogonadism-2 with or without anosmia (HH2) is caused by heterozygous mutation in the gene encoding fibroblast growth factor receptor-1 (FGFR1; 136350) on chromosome 8p11, sometimes in association with mutation in other genes, e.g., FGF8 (600483) and GNRHR (138850).
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.
There is evidence that mutation in 2 or more of these genes can work in combination (oligogenicity) to produce Gn RH-deficient conditions (summary by 21722705, images] [Full Text]" pmid="21722705"Sykiotis et al.
(2010), for example, demonstrated that of patients with an identifiable coding sequence mutation in 1 of 8 genes responsible for isolated Gn RH deficiency, 11% carried mutations in at least one other of these genes as well. (2013) analyzed 350 HH probands of European descent for mutation in 17 HH-associated genes.

The vocal folds, also known commonly as vocal cords or voice reeds, are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx.
They vibrate, modulating the flow of air being expelled from the lungs during phonation.
Mutations were identified in 124 (35%) of the probands, and 24 (19%) of the mutation-positive probands carried at least 2 mutant alleles from different genes.
