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]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 12, 2017 | In summary, this variant has uncertain impact on SCN9A function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with an SCN9A-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with lysine at codon 750 of the SCN9A protein (p.Met750Lys). The methionine residue is highly conserved and there is a moderate physicochemical difference between methionine and lysine. - |
