The tyrosine residue is weakly conserved and there is a large physicochemical difference between tyrosine and cysteine. This variant is present in population databases (rs587779150, ExAC 0.009%). This variant has been reported in individuals in the Universal Mutation Database (PMID: 10612827) and the Leiden Open-source Variation Database (PMID: 21520333). ClinVar contains an entry for this variant (Variation ID: 91003). An algorithm developed specifically for the MSH2 gene suggests that this missense change is likely to be tolerated (PMID: 26333163). However, this prediction has not been confirmed by published functional studies and its clinical significance is uncertain. 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.
