Invitae RCV000198343 SCV000254404 uncertain significance Lynch syndrome 2015-06-05 criteria provided, single submitter clinical testing This sequence change replaces glutamine with histidine at codon 76 of the MSH2 protein (p.Gln76His). The glutamine residue is weakly conserved and there is a small physicochemical difference between glutamine and histidine. This variant has not been published in the literature and is present in population databases (no rsID, <0.01%). ClinVar contains an entry for this variant (RCV000132473). 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, this is a rare missense change with uncertain impact on protein function. Although there is no indication that this variant causes disease, the evidence is insufficient at this time to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
