Invitae RCV000524724 SCV000625251 uncertain significance Hereditary nonpolyposis colon cancer 2017-03-27 criteria provided, single submitter clinical testing This sequence change replaces leucine with proline at codon 443 of the MSH2 protein (p.Leu443Pro). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and proline. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a MSH2-related disease. 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. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
