Labcorp Genetics (formerly Invitae), Labcorp RCV004569555 SCV000938019 uncertain significance Familial adenomatous polyposis 1 2018-11-28 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with APC-related conditions. 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"). 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. This sequence change replaces alanine with serine at codon 474 of the APC protein (p.Ala474Ser). The alanine residue is highly conserved and there is a moderate physicochemical difference between alanine and serine. This variant is not present in population databases (ExAC no frequency).
