Specifically, these differences can provide a critical substrate for developing life-threatening arrhythmias that originate in the right ventricle including the ventricular outflow tract in disorders such as Brugada syndrome, where inherited mutations of the gene that encodes Na+ channels (SCN5A) or the direct Notch signaling pathway target HEY2 (Hairy/enhancer-of-split related with YRPW motif protein 2), among other mutations, can result in ventricular arrhythmias and sudden cardiac death [16, 17]. This evidence concerns the gene HEY2 and Ventricular arrhythmia.
