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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with PRRT2-related conditions. This variant is present in population databases (rs760278435, ExAC 0.01%). This sequence change replaces proline with arginine at codon 152 of the PRRT2 protein (p.Pro152Arg). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and arginine. |
