Description

The MSH6 c.1082G>A variant is predicted to result in the amino acid substitution p.Arg361His. This variant was reported in a study of hereditary cancer variants in biliary tract cancer and was classified as a variant of uncertain significance (VUS) (Okawa et al. 2023. PubMed ID: 36243179, Supplementary Table 2). This variant is reported in 0.0054% of alleles in individuals of East Asian descent in gnomAD. In ClinVar, this variant was classified as VUS by the vast majority of the laboratories (https://preview.ncbi.nlm.nih.gov/clinvar/variation/89168/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
