RCV001842622 | SCV001339352 | uncertain significance | Cardiac arrhythmia | 2023-12-05 | criteria provided, single submitter | clinical testing | This missense variant replaces methionine with valine at codon 390 of the SCN5A protein. Computational prediction tools and conservation analyses suggest that this variant may have deleterious impact on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with cardiovascular disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
Invitae | RCV003656664 | SCV001512967 | uncertain significance | not provided | 2020-01-13 | criteria provided, single submitter | clinical testing | 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. 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 C15"). This variant has not been reported in the literature in individuals with SCN5A-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with valine at codon 390 of the SCN5A protein (p.Met390Val). The methionine residue is highly conserved and there is a small physicochemical difference between methionine and valine. |
