Due to the association with HBGA and enteric virus, GWAS has demonstrated the association between IBD and single nucleotide polymorphism (SNPs) of the FUT2 and FUT3 genes, which drive the synthesis of HBGA, and ligands for NoV and RV in the intestine (Tarris et al., 2021). The gene discussed is HBG1; the disease is inflammatory bowel disease.
