By comparing differentially expressed genes in DCM samples with that from healthy controls, we predict that CORIN, FIGF, CTGF, COL1A1, COL1A2, THBS4, THBS4, POSTN, COMP, PRELP and RPS4Y1 may play a role in development of DCM. This evidence concerns the gene COL1A2 and familial dilated cardiomyopathy.
