Invitae | RCV001065038 | SCV001229976 | uncertain significance | Colorectal cancer, susceptibility to, 10 | 2021-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with tryptophan at codon 910 of the POLD1 protein (p.Arg910Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has not been reported in the literature in individuals affected with POLD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 859028). 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"). 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. |
