PGAP3 and Crohn disease: The susceptibility allele was also associated with the increased expression of GSDMA (P = 1.6 × 10−4) and LRRC3C (P = 7.8 × 10−6) in colon tissue from individuals without IBD and with the reduced expression of PGAP3 (IBD; P = 2.0 × 10−3) and ZPBP2 (Crohn's disease; P = 7.7 × 10−4) in noninflamed ileum.
