Association of IL23R, TNFRSF1A, and HLA-DRB1*0103 allele variants with inflammatory bowel disease phenotypes in the Finnish population
AssociationN=7,457Maarit Lappalainen et al.(2008)· Inflammatory Bowel Diseases

PhD thesis describing comprehensive genome-wide association studies of acute anterior uveitis (AAU) in European (2,752 cases, 3,836 controls) and East Asian (821 cases, 4,898 controls) populations. European descent GWAS identified HLA-B at genome-wide significance plus 11 suggestive loci (ERAP1, NOS2, MERTK). East Asian GWAS identified HLA-B and ERAP1 at genome-wide significance plus 12 suggestive loci (GPR68, RHBDD2). Mendelian randomization confirmed ERAP1 as functionally relevant and showed genetically predicted CRP levels positively associated with AAU risk.

About FUT2

This gene is one of two encoding the galactoside 2-L-fucosyltransferase enzyme. The encoded protein is important for the final step in the soluble ABO blood group antigen synthesis pathway. It is also involved in cell-cell interaction, cell surface expression, and cell proliferation. Mutations in this gene are a cause of the H-Bombay blood group where red blood cells lack the H antigen.
