| Invitae | RCV003538422 | SCV000768037 | uncertain significance | Familial adenomatous polyposis 1 | 2021-03-12 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with glycine at codon 704 of the APC protein (p.Val704Gly). The valine residue is highly conserved and there is a moderate physicochemical difference between valine and glycine. This variant has not been reported in the literature in individuals with APC-related disease. 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. |
