Invitae | RCV001247238 | SCV001420647 | uncertain significance | Hereditary nonpolyposis colorectal neoplasms | 2021-09-29 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine with leucine at codon 274 of the MSH2 protein (p.Ile274Leu). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and leucine. 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. 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"). This variant has not been reported in the literature in individuals affected with MSH2-related conditions. This variant is not present in population databases (ExAC no frequency). |
