We used quantitative reverse-transcription PCR (RT-PCR) to validate the key genes Mef2a, Klf15, Bcl2l2, Cd36, and Slc25a33, which are associated with DCM pathophysiology and found that all of them were significantly enriched in immunoprecipitation (IP) pull-down samples (Figure 4E). The gene discussed is BCL2L2; the disease is familial dilated cardiomyopathy.
