AKT1 and dilated cardiomyopathy: As reported by the KEGG pathway analysis obtained from the clusterProfiler package, the DEGs were linked to pathways, including focal adhesion, dilated cardiomyopathy, protein digestion and absorption, hypertrophic cardiomyopathy, calcium signaling pathway, arrhythmogenic right ventricular cardiomyopathy, ECM-receptor interaction, PI3K-Akt signaling pathway, proteoglycans in cancer, and arginine and proline metabolism (Table 3).
