Invitae | RCV000226015 | SCV000284105 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2019-10-15 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine with valine at codon 443 of the MSH2 protein (p.Leu443Val). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and valine. 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 disease. ClinVar contains an entry for this variant (Variation ID: 232660). Algorithms developed to predict the effect of missense changes on protein structure and function 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. |
