Likewise, CARP is induced in patients with hypertrophic, dilated, ischemic, and arrhythmogenic right ventricular cardiomyopathy [16], [17], [18] and missense mutations in the Ankrd1 gene were recently shown to be causative for human dilated and hypertrophic cardiomyopathy [19], [20], [21]. Here, ANKRD1 is linked to arrhythmogenic right ventricular cardiomyopathy.
