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]

Collection Method:clinical testing

The c.3255G>C (p.E1085D) alteration is located in exon 18 (coding exon 18) of the SCN10A gene. This alteration results from a G to C substitution at nucleotide position 3255, causing the glutamic acid (E) at amino acid position 1085 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
