A Japanese study [97] on 9 cases of SUDEP performed next-generation sequencing to examine 73 genes related to inherited heart disease: the Authors found KCNE1 as pathogenic variants (together with KCNE1) and also 3 other potentially pathogenic variants (MYH6, DSP, DSG2) according to in silico analysis. Here, KCNE1 is linked to heart disorder.
