JPH2 and Arrhythmia: Of the 22 genes involved, the majority of these (n = 14; 63.63%) were associated with cardiomyopathy (DSP, JPH2, MYO6, MYPN, NDUFV2, NEBL, PRKAG2, RBM20, TNNT2, ILK, LAMA2, OBSCN, MYH7, MYOM1); six (27.27%) were susceptibility genes for arrhythmogenic cardiac dysfunction (AKAP9, KCNE1, SCN10A, TRPM4, ANK2, SCNN1A) and two (9.09%) genes (TBX5, DSG2) were both arrhythmia and cardiomyopathy associated.
