ClinVar
Submissions by phenotype
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Brugada syndrome Uncertain:1
This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 1750 of the SCN10A protein (p.Lys1750Arg). This variant is present in population databases (rs145589241, gnomAD 0.007%). 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: 572545). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
Cardiovascular phenotype Uncertain:1
The p.K1750R variant (also known as c.5249A>G), located in coding exon 27 of the SCN10A gene, results from an A to G substitution at nucleotide position 5249. The lysine at codon 1750 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
