Invitae | RCV003538522 | SCV000768274 | uncertain significance | Familial adenomatous polyposis 1 | 2017-10-23 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine with arginine at codon 2049 of the APC protein (p.Lys2049Arg). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and arginine. 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 do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with APC-related disease. This variant is not present in population databases (ExAC no frequency). |
