IL17A and Behcet disease: In the IVW approach, we identified significant associations between genetic liability to elevated levels of interleukin‐17 (IL‐17), macrophage inflammatory protein‐1α (MIP‐1α), and monocyte chemotactic protein 3 (MCP‐3) with increased risk of developing BD (odds ratio [OR] = 1.119, 95% confidence interval [CI] = 1.021–1.226, p = 0.016; OR = 1.084, 95% CI = 1.002–1.174, p = 0.044; OR = 1.060, 95% CI = 1.001–1.122, p = 0.046, respectively).
