The available evidence is currently insufficient to determine its role 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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C65"). This variant has not been reported in the literature in individuals with a MAT1A-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with alanine at codon 114 of the MAT1A protein (p.Ser114Ala). The serine residue is highly conserved and there is a moderate physicochemical difference between serine and alanine. |
