Additional funding was provided by NIH Grants R01-AR059049 (to A. Grom), R01-AR060893 (to S.P.), N1R01-AR062886 (to P.I.W.d.B.), AG030653, AG041718, and AG005133 (to M.I.K.), and U01-DK062420 and R01-DK076025 (to R.H.D.); Arthritis Research UK Grant 20385 (to W.T.); the Netherlands Organization for Scientific Research Project No. 016.126.354 (to P.I.W.d.B.); the Marcus Foundation (S.P.); the Wellcome Trust Grant 098051 (to E.Z.); the Val A. Browning Charitable Foundation (J.F.B.); and a Crohn''s & Colitis Foundation of America Senior Research Award (to R.H.D.). UK patient cohorts were supported by Arthritis Research UK (Grants 20542 and 20386). Sparks-CHARMS was funded by grants from SPARKS UK (08ICH09 and 12ICH08), the Medical Research Council (MR/M004600/1), and the UK National Institute for Health Research Medicines for Children Research Network. This study makes use of data generated by the Wellcome Trust Case-Control Consortium. A full list of the investigators who contributed to the generation of data is available at www.wtccc.org.uk. Funding for the project was provided by the Wellcome Trust under award 076113 and 085475.

N2 - Systemic juvenile idiopathic arthritis (sJIA) is an often severe, potentially life-threatening childhood inflammatory disease, the pathophysiology of which is poorly understood. To determine whether genetic variation within the MHC locus on chromosome 6 influences sJIA susceptibility, we performed an association study of 982 children with sJIA and 8,010 healthy control subjects from nine countries. Using meta-analysis of directly observed and imputed SNP genotypes and imputed classic HLA types, we identified the MHC locus as a bona fide susceptibility locus with effects on sJIA risk that transcended geographically defined strata. The strongest sJIA-associated SNP, rs151043342 [P = 2.8 × 10-17, odds ratio (OR) 2.6 (2.1, 3.3)], was part of a cluster of 482 sJIA-associated SNPs that spanned a 400-kb region and included the class II HLA region. Conditional analysis controlling for the effect of rs151043342 found that rs12722051 independently influenced sJIA risk [P = 1.0 × 10-5, OR 0.7 (0.6, 0.8)]. Meta-analysis of imputed classic HLA-type associations in six study populations of Western European ancestry revealed that HLA-DRB1∗11 and its defining amino acid residue, glutamate 58, were strongly associated with sJIA [P = 2.7 × 10-16, OR 2.3 (1.9, 2.8)], as was the HLA-DRB1∗11-HLADQA1∗ 05-HLA-DQB1∗03 haplotype [6.4 × 10-17, OR 2.3 (1.9, 2.9)]. By examining the MHC locus in the largest collection of sJIA patients assembled to date, this study solidifies the relationship between the class II HLA region and sJIA, implicating adaptive immune molecules in the pathogenesis of sJIA.
