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)). The gene discussed is E2F2; the disease is Arrhythmogenic right ventricular dysplasia.
