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)

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 2-166276970-TCT-AA is Benign according to our data. Variant chr2-166276970-TCT-AA is described in ClinVar as [Likely_benign]. Clinvar id is 258883.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
