POPDC2 and familial dilated cardiomyopathy: The results identified five hub genes—phospholamban (Pln), fatty acid binding protein 3 (Fabp3), tripartite motif‐containing protein 63 (Trim63), popeye domain containing 2 (Popdc2), and troponin C1 (Tnnc1)—related to ceRNA, which are accountable for the onset of DCM [123].
