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

Classification made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.56).
BP6
Variant 2-166228787-A-G is Benign according to our data. Variant chr2-166228787-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 285950.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Benign=1, Uncertain_significance=1}. Variant chr2-166228787-A-G is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=0.5 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000198 (289/1461676) while in subpopulation MID AF= 0.0106 (61/5768). AF 95% confidence interval is 0.00845. There are 8 homozygotes in gnomad4_exome. There are 158 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 8 SD gene

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
