Description

This variant is not present in population databases (gnomAD no frequency). 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. Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (PMID: 33357406) indicates that this missense variant is not expected to disrupt MSH2 function. ClinVar contains an entry for this variant (Variation ID: 237415). This missense change has been observed in individual(s) with colon cancer (PMID: 29212164). This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 31 of the MSH2 protein (p.Thr31Ser).
