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]

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 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). -

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
Nov 13, 2024
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. -
