Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 4P and 4B. PP3_StrongBS2
The NM_006514.4(SCN10A):c.2414G>T(p.Gly805Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000347 in 1,614,018 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G805D) has been classified as Uncertain significance.

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 expected to disrupt SCN10A protein function. ClinVar contains an entry for this variant (Variation ID: 574720). This missense change has been observed in individual(s) with clinical features of SCN10A-related disease (PMID: 30177317). This variant is present in population databases (rs779733116, gnomAD 0.006%). This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 805 of the SCN10A protein (p.Gly805Val). -
not provided Uncertain:1
Identified in a patient with sudden cardiac arrest and an abnormal ECG (Di Stolfo et al., 2018); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 34426522, 30177317, 27535533, 26582918) -
Cardiovascular phenotype Uncertain:1
The c.2414G>T (p.G805V) alteration is located in exon 15 (coding exon 15) of the SCN10A gene. This alteration results from a G to T substitution at nucleotide position 2414, causing the glycine (G) at amino acid position 805 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
