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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.5107G>A (p.D1703N) alteration is located in exon 27 (coding exon 26) of the SCN9A gene. This alteration results from a G to A substitution at nucleotide position 5107, causing the aspartic acid (D) at amino acid position 1703 to be replaced by an asparagine (N). The alteration is ultra rare in population databases:_x000D_ _x000D_ Based on data from the Genome Aggregation Database (gnomAD), the SCN9A c.5107G>A alteration was observed in 0.002% (5/250,884) of total alleles studied. The altered amino acid is conserved throughout evolution:_x000D_ _x000D_ The p.D1703 amino acid is conserved in available vertebrate species. In silico prediction is conflicting:_x000D_ _x000D_ The p.D1703N alteration is predicted to be probably damaging by Polyphen and tolerated by SIFT in silico analyses. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 1703 of the SCN9A protein (p.Asp1703Asn). This variant is present in population databases (rs200733722, gnomAD 0.004%). 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: 471139). 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 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. -
