MEG3 and Hirschsprung disease: Given the role of lncRNAs in neural diseases, the importance of the relation between lncRNAs and miRNAs in the pathophysiologic mechanism, and the MEG3 and miR-770-5p were abnormally decreased in HSCR, we speculated that MEG3, miR-770-5p may be involved in the pathogenesis of HSCR.
