A small number of other genes were regulated inversely in different adult forms of cardiomyopathy (RCM/DCM or RCM/ICM datasets) relative to RCM, including intelectin 1 (ITLN1), delta-like 1 homolog (DLK1), reelin (RELN), and myosin light chain kinase family, member 4 (MYLK4). This evidence concerns the gene RELN and cardiomyopathy.
