GeneDx RCV001732556 SCV001982774 uncertain significance not provided 2021-04-05 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function
Ambry Genetics RCV003298957 SCV004000491 uncertain significance Cardiovascular phenotype 2023-04-04 criteria provided, single submitter clinical testing The p.S102C variant (also known as c.305C>G), located in coding exon 2 of the SCN10A gene, results from a C to G substitution at nucleotide position 305. The serine at codon 102 is replaced by cysteine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV005094911 SCV005811750 uncertain significance Brugada syndrome 2025-01-11 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 102 of the SCN10A protein (p.Ser102Cys). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with SCN10A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1300650). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SCN10A protein function with a negative predictive value of 80%. 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.
