Multiple miRNAs demonstrated strong associations with various IGFBPs, including miR-518d-5p and miR-520a-5p with IGFBP-4 (r = 0.604, p < 0.001), and miR-517a-3p with IGFBP-4 (r = 0.567, p < 0.001), all observed in GDM patients with normal birthweight. The gene discussed is IGFBP4; the disease is gestational diabetes.
