Alternatively spliced RNA elements of pivotal myocardial genes, such as actin gamma 1 (ACTG1), myosin light chain 2 (MYL2), ryanodine receptor 2 (RYR2), troponin I3 (TNNI3), troponin T2 (TNNT2), tropomyosin 1 (TPM1), tropomyosin 2 (TPM2), and titin (TTN; Table 1), were enriched by SLM2 RIP in DCM samples (Figure 4C). Here, TNNT2 is linked to familial dilated cardiomyopathy.
