RCV000807966 | SCV000948048 | uncertain significance | Familial hyperkalemic periodic paralysis | 2022-07-06 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with SCN4A-related conditions. This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 932 of the SCN4A protein (p.Asp932Ala). This variant is not present in population databases (gnomAD no frequency). ClinVar contains an entry for this variant (Variation ID: 652422). 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 C65"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
