A mutation in the genes for lamin A/C (LMNA), desmoplakin (DSP) producing gene, sodium voltage-gated channel alpha subunit 5 (SCN5A) gene, and filamin C (FLNC) are genetic markers associated with DCMs that caused a higher risk in sudden cardiac death (SCD) related to malignant arrhythmias [22]. This evidence concerns the gene SCN5A and Schnyder corneal dystrophy.
