CUEDC1 and familial dilated cardiomyopathy: In the present study, the top 10 differentially expressed lncRNAs like Hmga1b, Gm8909, Gm50252, Cuedc1, Dyrk1a, Msantd4, 4933413J09Rik, Gm41414, 2310015A16Rik, Hand2os1 has not yet been reported in myocardium in DCM, which maybe signify that more and more differentially expressed lncRNAs would be found in pathogenesis of DCM with the development of biotechnology.
