Invitae | RCV000646295 | SCV000768063 | uncertain significance | Familial adenomatous polyposis 1 | 2018-05-12 | criteria provided, single submitter | clinical testing | This sequence change replaces valine with isoleucine at codon 754 of the APC protein (p.Val754Ile). The valine residue is highly conserved and there is a small physicochemical difference between valine and isoleucine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with APC-related disease. ClinVar contains an entry for this variant (Variation ID: 230625). 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: "Possibly 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. |
