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 GPR35

Enables C-X-C chemokine receptor activity. Involved in chemokine-mediated signaling pathway; negative regulation of voltage-gated calcium channel activity; and positive regulation of cytosolic calcium ion concentration. Located in plasma membrane. [provided by Alliance of Genome Resources, Jul 2025]
