Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 4P and 4B. PP3_StrongBS2
The NM_006514.4(SCN10A):c.4094C>A(p.Thr1365Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000753 in 1,461,336 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. T1365A) has been classified as Uncertain significance.

Submissions by phenotype
Brugada syndrome Uncertain:1
This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 1365 of the SCN10A protein (p.Thr1365Asn). This variant is present in population databases (rs748854017, 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: 463255). 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 expected to disrupt SCN10A protein function with a positive 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.
Cardiovascular phenotype Uncertain:1
The c.4094C>A (p.T1365N) alteration is located in exon 23 (coding exon 23) of the SCN10A gene. This alteration results from a C to A substitution at nucleotide position 4094, causing the threonine (T) at amino acid position 1365 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
