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.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0025099218).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.162 is higher than 0.05.
