MFAP4, IDI2, GATM, and TCEA2 were negatively associated with CKD in at least 2 datasets, where the corresponding combined ORs and 95% CIs were 0.80 (0.75–0.86), 0.80 (0.76–0.85), 0.81 (0.78–0.84), and 0.85 (0.80–0.90), respectively. The gene discussed is IDI2; the disease is chronic kidney disease.
