TRAF1 and juvenile idiopathic arthritis: However, the TRAF1/C5 AA allele at chr9:120942809 (GRCh38.p12; rs10818488) which is in strong linkage disequilibrium with an SNP at chr9:120927961 (GRCh38.p12; rs3761847) in Caucasian and Asian populations [72], while just missing significance level (p = 0.06) in oligoarticular and polyarticular RF-negative JIA, is associated with increased uveitis risk in ANA positive oligoarticular and polyarticular JIA patients.
