Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses of genes that were differentially expressed between the groups revealed arrhythmogenic cardiomyopathy, dilated cardiomyopathy and hypertrophic cardiomyopathy as top-ranked pathways for upregulated genes in the high CERS2 expression group (Figure 3B). Here, CERS2 is linked to hypertrophic cardiomyopathy.
