Invitae RCV000200127 SCV000254379 uncertain significance Hereditary nonpolyposis colon cancer 2018-12-13 criteria provided, single submitter clinical testing This sequence change replaces isoleucine with methionine at codon 418 of the MSH2 protein (p.Ile418Met). The isoleucine residue is weakly conserved and there is a small physicochemical difference between isoleucine and methionine. This variant is present in population databases (rs751431238, ExAC 0.01%). This variant has not been reported in the literature in individuals with MSH2-related disease. ClinVar contains an entry for this variant (Variation ID: 216341). 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 tolerated, 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.
