PPARA and hypertrophic cardiomyopathy: KEGG pathway enrichment analysis revealed that these DEGs were significantly enriched in metabolism- and cardiomyopathy-related pathways, such as oxidative phosphorylation, thermogenesis, cardiac muscle contraction, proteasome, glycolysis/gluconeogenesis, hypertrophic cardiomyopathy (HCM), phagosome, dilated cardiomyopathy, HIF-1 signaling pathway, mitophagy—animal, PPAR signaling pathway and biosynthesis of amino acids (Figure 3B).
