Genes affected
TRPV6 (HGNC:14006): (transient receptor potential cation channel subfamily V member 6) This gene encodes a member of a family of multipass membrane proteins that functions as calcium channels. The encoded protein contains N-terminal ankyrin repeats, which are required for channel assembly and regulation. Translation initiation for this protein occurs at a non-AUG start codon that is decoded as methionine. This gene is situated next to a closely related gene for transient receptor potential cation channel subfamily V member 5 (TRPV5). This locus has experienced positive selection in non-African populations, resulting in several non-synonymous codon differences among individuals of different genetic backgrounds.

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 695 of the TRPV6 protein (p.Gly695Ser). This variant is present in population databases (rs200385286, gnomAD 0.2%). This missense change has been observed in individual(s) with TRPV6-related conditions (PMID: 32383311). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
