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 IL27

The protein encoded by this gene is one of the subunits of a heterodimeric cytokine complex. This protein is related to interleukin 12A (IL12A). It interacts with Epstein-Barr virus induced gene 3 (EBI3), a protein similar to interleukin 12B (IL12B), and forms a complex that has been shown to drive rapid expansion of naive but not memory CD4(+) T cells. The complex is also found to synergize strongly with interleukin 12 to trigger interferon gamma (IFNG) production of naive CD4(+) T cells. The biological effects of this cytokine are mediated by the class I cytokine receptor (WSX1/TCRR). [provided by RefSeq, Jul 2008]
