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]

Likely pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Jun 25, 2015	The R386P variant in the KISS1R gene has reported in the heterozygous state in an female with central precocious puberty (Teles et al., 2008). The R386P variant was not observed in approximately 5,300 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The R386P variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, this substitution occurs at a position that is not conserved across species. In vitro studies indicate that R386P results in prolonged activation of intracellular GPR54 signaling pathways in response kisspeptin, suggestive of a gain-of-function effect (Teles et al., 2008; Bianco et al., 2011). Given the available data, we consider R386P to be a strong candidate for a disease-causing variant; however, the possibility it may be a rare benign variant cannot be excluded. -
