Interestingly, PDHA1, VDAC2, ACADM, ACADVL, ACAT1, ECH1, CKMT2, MYL2, MYOZ2, TNNT2, and TPM1 expressions were upregulated in DCM and idiopathic dilated cardiomyopathy patients, while A2M, APCS, C3, SERPINA1, GSTM2, GSTM3, PRDX1, PRDX6, GPX3, NPPA, and APOA1 expressions were downregulated in DCM and idiopathic dilated cardiomyopathy patients. Here, ACADVL is linked to idiopathic dilated cardiomyopathy.
