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.4109G>A (p.R1370Q) alteration is located in exon 22 (coding exon 21) of the SCN9A gene. This alteration results from a G to A substitution at nucleotide position 4109, causing the arginine (R) at amino acid position 1370 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
