For instance, we identified SCN5A, KCND3, KCNQ1, and KCNE1, genes with well-established associations to various arrhythmic disorders9,12 along with cardiomyopathy genes including DPT, TTN, PLN (at the SLC35F1 locus), BAG3, and MYH7B. 13Gene-set analyses revealed that the genetic signals could be parcellated into interlinked aspects of cardiac physiology namely, development, contractility and electrophysiology. Here, KCND3 is linked to cardiomyopathy.
