Similarly, a p.W1095X (or p.Trp1095STOP) missense mutation in the SCN5A gene has been identified in subjects showing both Brugada symptoms and epilepsy [98]; and another SCN5A mutation (Pro1090Leu) previously associated with SCD and LQTS, has been found in a SUDEP victim [94]. This evidence concerns the gene SCN5A and familial long QT syndrome.
