FUT2 and colorectal adenocarcinoma: To further investigate the relationship between CRC and IBD risk we performed eQTL analysis on the 12 IBD SNPs associated with CRC risk in the colorectal adenocarcinoma data, and found two significant relationships between rs174537 and the expression of fatty acid desaturase 2 (FADS2, FDR P-value = 3.28 × 10−6) and between rs516246 and fucosyltransferase 2 (FUT2, FDR P-value = 2.08 × 10−17) (Supplementary Material, Table S6).
