Genes affected

CA6 (HGNC:1380): (carbonic anhydrase 6) The protein encoded by this gene is one of several isozymes of carbonic anhydrase. This protein is found only in salivary glands and saliva and protein may play a role in the reversible hydratation of carbon dioxide though its function in saliva is unknown.

The c.496G>A (p.V166I) alteration is located in exon 4 (coding exon 4) of the CA6 gene. This alteration results from a G to A substitution at nucleotide position 496, causing the valine (V) at amino acid position 166 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
