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]
SCN1A-AS1 (HGNC:54069): (SCN1A and SCN9A antisense RNA 1)

Inborn genetic diseases Uncertain:1
Feb 06, 2023
Ambry Genetics
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.1135A>G (p.M379V) alteration is located in exon 10 (coding exon 9) of the SCN9A gene. This alteration results from a A to G substitution at nucleotide position 1135, causing the methionine (M) at amino acid position 379 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

SCN9A-related disorder Uncertain:1
Mar 28, 2023
PreventionGenetics, part of Exact Sciences
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The SCN9A c.1135A>G variant is predicted to result in the amino acid substitution p.Met379Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.073% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/2-167145126-T-C). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
