ITIH4 and Behcet disease: After the integrative analysis, we identified 52 TFBRs target genes, 44 TADs target genes, 55 CIRs target genes and 21 lncRNAs target genes for BD, such as ITIH4 (Pdataset1 = 6.68 × 10−8, Pdataset2 = 6.64 × 10−7), ITIH3 (Pdataset1 = 1.09 × 10−8, Pdataset2 = 2.00 × 10−7), SYNE1 (Pdataset1 = 1.80 × 10−6, Pdataset2 = 4.33 × 10−9) and OPRM1 (Pdataset1 = 1.80 × 10−6, Pdataset2 = 4.33 × 10−9).
