RCV002933155 | SCV003265356 | uncertain significance | Brugada syndrome | 2022-05-05 | 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SCN10A protein function. This variant has not been reported in the literature in individuals affected with SCN10A-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 281 of the SCN10A protein (p.Met281Arg). |
| Ambry Genetics | RCV003170597 | SCV003909021 | uncertain significance | Cardiovascular phenotype | 2022-12-01 | criteria provided, single submitter | clinical testing | The p.M281R variant (also known as c.842T>G), located in coding exon 6 of the SCN10A gene, results from a T to G substitution at nucleotide position 842. The methionine at codon 281 is replaced by arginine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
