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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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 proline with alanine at codon 1354 of the SCN9A protein (p.Pro1354Ala). The proline residue is weakly conserved and there is a small physicochemical difference between proline and alanine. |
