An IL23R–IL12RB2 intergenic SNP rs1495965 was significantly associated with BD risk (OR (95% CI) = 1.5 (1.3, 1.7), P = 2.5 × 10−7) in the pooled meta-analysis of the discovery (1.4 (1.2, 1.7), P = 4.9 × 10−7) and replication (1.9 (1.3, 2.6), P = 6.0 × 10−4) phases. This evidence concerns the gene IL23R and Behcet disease.
