In particular, minor alleles of FUT3 polymorphisms appear to increase susceptibility to ulcerative colitis (63), whereas minor alleles of FUT2 polymorphism are associated with increased susceptibility to celiac disease (64), as well as increased risks of Escherichia coli (65) and Staphylococcus aureus (66) infections. This evidence concerns the gene FUT2 and ulcerative colitis.
