Invitae RCV000811925 SCV000952217 uncertain significance Colorectal cancer, susceptibility to, 10 2021-07-07 criteria provided, single submitter clinical testing 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: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with POLD1-related conditions. This variant is present in population databases (rs771700024, ExAC 0.008%). This sequence change replaces arginine with histidine at codon 808 of the POLD1 protein (p.Arg808His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine.
