Invitae RCV000793779 SCV000933151 uncertain significance Hereditary nonpolyposis colon cancer 2018-12-05 criteria provided, single submitter clinical testing This sequence change replaces arginine with threonine at codon 106 of the MSH2 protein (p.Arg106Thr). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and threonine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MSH2-related conditions. ClinVar contains an entry for this variant (Variation ID: 483749). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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.
