After data normalization (Figure 1A and B) anddifferential expression analysis, a total of 4777 DEGs were identified in DCM andnormal samples, including 2711 up-regulated genes and 2066 down-regulated genes.Genes like PRSS12 (protease serine 12, log2 FC=-0.167 and FDR=0.003)and FOXG1 (forkhead box G1, log2 FC =-0.156 and FDR=0.045) weresignificantly down-regulated in DCM samples in comparison with normal samples. This evidence concerns the gene PRSS12 and familial dilated cardiomyopathy.
