Recently, a panel of international experts conducted a rigorous reappraisal of 26 ARVC genes reported in the literature using the semi-quantitative ClinGen framework and found only eight genes had definitive (PKP2, DSP, DSG2, DSC2, JUP, TMEM43) or moderate (PLN, DES) evidence for causing ARVC (Figure 4) (35). The gene discussed is TMEM43; the disease is arrhythmogenic right ventricular cardiomyopathy.
