Genes affected

SCN9A (HGNC:10597): (sodium voltage-gated channel alpha subunit 9) This gene encodes a voltage-gated sodium channel which plays a significant role in nociception signaling. Mutations in this gene have been associated with primary erythermalgia, channelopathy-associated insensitivity to pain, and paroxysmal extreme pain disorder. [provided by RefSeq, Aug 2009]

Collection Method:clinical testing

The c.3023A>G (p.K1008R) alteration is located in exon 17 (coding exon 16) of the SCN9A gene. This alteration results from a A to G substitution at nucleotide position 3023, causing the lysine (K) at amino acid position 1008 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Collection Method:clinical testing

This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 1008 of the SCN9A protein (p.Lys1008Arg). This variant is present in population databases (rs201979706, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with SCN9A-related conditions. ClinVar contains an entry for this variant (Variation ID: 538450). 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 not expected to disrupt SCN9A protein function with a negative predictive value of 95%. 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. -
