Molecular assay reagents intended to identify deletions or duplications of the sodium voltage-gated channel alpha subunit 5 (SCN5A) gene, located at chromosome 3p22.2, which encodes the protein sodium channel protein type 5 subunit alpha. Genetic variants at this locus have been associated with Brugada syndrome, dilated cardiomyopathy, familial atrial fibrillation, long QT syndrome, paroxysmal familial ventricular fibrillation, progressive familial heart block, sick sinus syndrome, and sudden infant death syndrome.
