Invitae RCV000558829 SCV000625170 uncertain significance Hereditary nonpolyposis colon cancer 2018-11-16 criteria provided, single submitter clinical testing This sequence change replaces lysine with asparagine at codon 164 of the MLH1 protein (p.Lys164Asn). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and asparagine. This variant is present in population databases (rs765014361, ExAC 0.003%). This variant has not been reported in the literature in individuals with MLH1-related disease. 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 C65"). 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.
