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]

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change disrupts the translational stop signal of the KISS1R mRNA. It is expected to extend the length of the KISS1R protein by an uncertain number of additional amino acid residues. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This protein extension has been observed in individuals with hypogonadotropic hypogonadism (PMID: 14573733, 23349759, 31073722). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 5757). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this protein extension affects KISS1R function (PMID: 14573733). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -

Stop codon loss and change to an arginine codon, leading to protein extension and the addition of an unknown number of amino acids at the C-terminus, and other similar variants have been reported in HGMD; Published functional studies suggest a damaging effect on ligand-induced inositol production and mRNA stability (PMID: 14573733); This variant is associated with the following publications: (PMID: 30205368, 34970798, 27094476, 20816945, 30339828, 16757106, 23349759, 14573733, 31073722, 26510589) -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The KISS1R c.1195T>A variant is predicted to result in extension of the open reading frame (p.*399Argext*89). This variant is predicted to disrupt the translation stop signal and result in protein extension. This variant was reported in the homozygous or compound heterozygous state in individuals with hypogonadotropic hypogonadism (Seminara. 2003. PubMed ID: 14573733; Brioude. 2013. PubMed ID: 23349759; Moalla. 2019. PubMed ID: 31073722). This variant is reported in 0.018% of alleles in individuals of European (Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-920746-T-A). This variant is interpreted as likely pathogenic. -
