Specific association of IL17A genetic variants with panuveitis.

2015

Background/aims A pathogenic role of Th17 cells in uveitis has become clear in recent years. Therefore, in the present study, we aimed to evaluate the possible influence of the IL 17A locus on susceptibility to non-anterior uveitis and its main clinical subgroups. Methods Five IL17A polymorphisms (rs4711998, rs8193036, rs3819024, rs2275913 and rs7747909), selected by tagging, were genotyped using TagMan assays in 353 Spanish patients with non-anterior uveitis and 1851 ethnically matched controls. Results The case/control analysis yielded a consistent association between two of the analysed genetic variants, rs8193036 and rs2275913, and the presence of panuveitis under a dominant model (p(FD…
