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.

The c.1921C>T (p.R641W) alteration is located in exon 15 (coding exon 15) of the TRPV6 gene. This alteration results from a C to T substitution at nucleotide position 1921, causing the arginine (R) at amino acid position 641 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
