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 C25"). This variant has not been reported in the literature in individuals with SCN9A-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with arginine at codon 1235 of the SCN9A protein (p.Ile1235Arg). The isoleucine residue is weakly conserved and there is a moderate physicochemical difference between isoleucine and arginine. |
