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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1744G>A (p.E582K) alteration is located in exon 12 (coding exon 11) of the SCN9A gene. This alteration results from a G to A substitution at nucleotide position 1744, causing the glutamic acid (E) at amino acid position 582 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 582 of the SCN9A protein (p.Glu582Lys). This variant is present in population databases (rs201391809, gnomAD 0.03%). This missense change has been observed in individual(s) with Dravet syndrome. However, this individual was also observed to carry a de novo pathogenic variant in SCN1A (PMID: 23895530). ClinVar contains an entry for this variant (Variation ID: 538474). 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. -
