NEXN and dilated cardiomyopathy: For example, mutations in JUP, DSP, PKP2, DSG2, DSC2, CTNNA3, CDH2, or PLN (all of them more abundant in LV) predominantly lead to arrhythmogenic right ventricular cardiomyopathy, and mutations in MYH7, HSPB7, NEXN and MYPN (also all more abundant in LV) lead to dilated cardiomyopathy.
