The GSEA enrichment analysis demonstrated that E2F2 is closely associated with arrhythmogenic right ventricular cardiomyopathy, cell circle, dilated cardiomyopathy, DNA replication, hypertrophic cardiomyopathy hcm, and spliceosome (Figure 9(a)). Here, E2F2 is linked to arrhythmogenic right ventricular cardiomyopathy.
