In the haplotype analysis (Table S2), DCAF12 (C-A, P = 2.4 × 10−3), IL10 (G-C-C, P = 7.3 × 10−3), PLCB1 (C-C-T-T-G, P = 1.5 × 10−2), SCHIP1 (G-C, P = 3.2 × 10−3), and TGFBR3 (C-C-G, P = 2.2 × 10−2) showed associations with intestinal BD development. This evidence concerns the gene PLCB1 and Behcet disease.
