Genes affected

SCN10A (HGNC:10582): (sodium voltage-gated channel alpha subunit 10) The protein encoded by this gene is a tetrodotoxin-resistant voltage-gated sodium channel alpha subunit. The properties of the channel formed by the encoded transmembrane protein can be altered by interaction with different beta subunits. This protein may be involved in the onset of pain associated with peripheral neuropathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

Variant summary: SCN10A c.905G>A (p.Arg302Gln) results in a conservative amino acid change located in the ion transport domain (IPR005821) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0004 in 1613904 control chromosomes, predominantly at a frequency of 0.00047 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 75 fold of the estimated maximal expected allele frequency for a pathogenic variant in SCN10A causing Arrhythmia phenotype (6.3e-06). c.905G>A has been reported in the literature (Le Scouarnec_2015). However, this report does not provide unequivocal conclusions about association of the variant with Arrhythmia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 25650408). ClinVar contains an entry for this variant (Variation ID: 376797). Based on the evidence outlined above, the variant was classified as likely benign. -

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. -
