Genes affected
KISS1R (HGNC:4510): (KISS1 receptor) The protein encoded by this gene is a galanin-like G protein-coupled receptor that binds metastin, a peptide encoded by the metastasis suppressor gene KISS1. The tissue distribution of the expressed gene suggests that it is involved in the regulation of endocrine function, and this is supported by the finding that this gene appears to play a role in the onset of puberty. Mutations in this gene have been associated with hypogonadotropic hypogonadism and central precocious puberty. [provided by RefSeq, Jul 2008]

Observed with another KISS1R variant in a patient with congenital hypogonadotropic hypogonadism in published literature (Brioude et al., 2013); Published functional studies demonstrate a damaging effect on the function of the KISSR1 receptor protein; variant may also delay rather than completely impair the maturation of the hypothalamic-pituitary-gonadal axis (Tenenbaum-Rakover et al., 2007); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 12944565, 17164310, 25147978, 31589614, 30205368, 31885997, 20816945, 23349759) -
