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]

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. This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1956 of the SCN10A protein (p.Pro1956Thr). 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: 463270). This variant has not been reported in the literature in individuals affected with SCN10A-related conditions. This variant is present in population databases (rs748441157, gnomAD 0.01%). -

The c.5866C>A (p.P1956T) alteration is located in exon 27 (coding exon 27) of the SCN10A gene. This alteration results from a C to A substitution at nucleotide position 5866, causing the proline (P) at amino acid position 1956 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
