In fifty percent of cases, the ARVD is caused by some autosomal dominant mutation in gene encoding desmosomal proteins like desmoplakin (DSP), plakoglobin (JUP), plakophilin-2 (PKP2), desmoglein-2 (DSG2) and desmocollin-2 (DSC2) [57]. Here, PKP2 is linked to arrhythmogenic right ventricular cardiomyopathy.
