PKP2 and heart failure: We found several studies that have reported genes associated with cardiomyopathies and heart failure such as myosin heavy chain 7 (MYH7), troponin T (TNNT2), troponin I (TNNI3), cardiac myosin binding protein 3 (MYBPC3), tropomyosin alpha-1 (TPM1), Lamin A/C (LMNA/C), plakophilin 2 (PKP2), desmocollin 2 (DSC2), desmoglein 2 (DSG2), desmoplakin (DSP), plakoglobin (JUP) and titin (194).
