Furthermore, various genes encoding cardiac cytoskeletal proteins such as dystrophin (DMD) for Duchenne muscular dystrophy, sarcoglycan (SGC) for sarcolemmal instability muscular dystrophy, and filamin C (FLNC) are associated with arrhythmias and SCD (Figure 2) [31]. This evidence concerns the gene FLNC and Duchenne muscular dystrophy.
