SCN1A and epilepsy: A recent review suggests different genes potentially contributing to SUDEP: (i) sodium and potassium ion channels subunits were the most frequently reported variants discovered by molecular autopsy, (ii) the DEPDC5 gene was the second‐highest ranked variant, (iii) the majority of DS patients carried a pathogenic variant in the SCN1A gene, and (iv) CNVs in chromosome 15 were associated with autism and a high frequency of epilepsy and SUDEP.6
