A previous post-mortem genetic analysis on 48 SUDEP cases found some non-synonymous variants in KCNH2 and SCN5A (Arg176Trp and Arg1047Leu in KCNH2, Ala572Asp, Pro1090Leu and Pro2006Ala in SCN5A) of which two (SCN5A Pro1090Leu and KCNH2 Arg176Trp) were already found in SQTL and were directly involved in the mechanism of death [89]. This evidence concerns the gene SCN5A and Sudden unexpected death in epilepsy.
