Genes affected
SCN10A (HGNC:10582): (sodium voltage-gated channel alpha subunit 10) The protein encoded by this gene is a tetrodotoxin-resistant voltage-gated sodium channel alpha subunit. The properties of the channel formed by the encoded transmembrane protein can be altered by interaction with different beta subunits. This protein may be involved in the onset of pain associated with peripheral neuropathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

Submissions by phenotype

Brugada syndrome Uncertain:1
Jun 04, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

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
Dec 17, 2024
Ambry Genetics
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

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. -
