Invitae | RCV000802405 | SCV000942236 | uncertain significance | Cowden syndrome | 2018-10-30 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals with PIK3CA-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with alanine at codon 876 of the PIK3CA protein (p.Thr876Ala). The threonine residue is highly conserved and there is a small physicochemical difference between threonine and alanine. 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. |
