Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_006514.4(SCN10A):c.3191C>T(p.Thr1064Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000747 in 1,606,342 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. T1064T) has been classified as Benign.

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: 576536). This variant has not been reported in the literature in individuals affected with SCN10A-related conditions. This variant is present in population databases (rs774803610, gnomAD 0.005%). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 1064 of the SCN10A protein (p.Thr1064Met). -
Cardiovascular phenotype Uncertain:1
The c.3191C>T (p.T1064M) alteration is located in exon 17 (coding exon 17) of the SCN10A gene. This alteration results from a C to T substitution at nucleotide position 3191, causing the threonine (T) at amino acid position 1064 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
