Whole Blood Transcriptome Profiling in Juvenile Idiopathic Arthritis and Inflammatory Bowel Disease

We report whole blood gene expression of 12 healthy controls and 190 patients with either oligoarticular (n=43), polyarticular (n=46), or systemic JIA (n=26), or Crohn's disease (n=60) and ulcerative colitis (n=15). The subtypes of JIA are characterized by a gradient of differential gene expression ranging from controls to oligoJIA, polyJIA, sJIA, and IBD. Whole blood samples were obtained from JIA patients age <17 years. Transcriptome profiling was performed with RNA-Seq.
