Submissions by phenotype
Brugada syndrome Uncertain:1
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. ClinVar contains an entry for this variant (Variation ID: 532118). This variant has not been reported in the literature in individuals affected with SCN10A-related conditions. This variant is present in population databases (rs747174454, gnomAD 0.0009%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 9 of the SCN10A protein (p.Glu9Lys). -
Cardiovascular phenotype Uncertain:1
The p.E9K variant (also known as c.25G>A), located in coding exon 1 of the SCN10A gene, results from a G to A substitution at nucleotide position 25. The glutamic acid at codon 9 is replaced by lysine, 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. Based on the available evidence, the clinical significance of this alteration remains unclear. -
