Invitae RCV000199509 SCV000254405 uncertain significance Hereditary nonpolyposis colon cancer 2018-12-10 criteria provided, single submitter clinical testing This sequence change replaces alanine with threonine at codon 765 of the MSH2 protein (p.Ala765Thr). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and threonine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in an individual affected with pancreatic cancer (PMID: 25479140). ClinVar contains an entry for this variant (Variation ID: 216353). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their 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.
