A comparison of SNPs between intestinal BD and BD without intestinal involvement showed an intestinal BD-specific association of the YIPF7 gene locus (rs6838327, odds ratio [OR] = 1.567, combined P = 3.5 × 10−4, Table 2) after Bonferroni correction (P < 0.05/44 SNPs). The gene discussed is YIPF7; the disease is Behcet disease.
