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]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 374104). This premature translational stop signal has been observed in individual(s) with insensitivity to pain (PMID: 374104). This variant is present in population databases (no rsID available, gnomAD 0.004%). This sequence change creates a premature translational stop signal (p.Arg548*) in the SCN9A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SCN9A are known to be pathogenic (PMID: 17470132, 19304393). -
