Highlights 1. An IDD-related ceRNA network involving four circRNAs, three miRNAs and 11 mRNAs was constructed. 2. The expression levels of miR-185-5p, miR-486-5p, FOXO1, SMAD2 and TGFB1 were consistent in different databases. 3. Our study identified IDD-related circRNA–miRNA–mRNA interaction axes, including circRNA_100086–miR-509-3p–MAPK1.
