RCV000465972 | SCV000547175 | uncertain significance | Brugada syndrome | 2018-09-07 | criteria provided, single submitter | clinical testing | This sequence change replaces proline with alanine at codon 952 of the SCN10A protein (p.Pro952Ala). The proline residue is weakly conserved and there is a small physicochemical difference between proline and alanine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a SCN10A-related disease. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. 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. |
