These included some well-known JIA-associated genes, such as SGF29 (p = 2.22 × 10−8 and FDR = 3.38 × 10−5 for Whole Blood), ANKRD55 (p = 3.09 × 10−8 and FDR = 1.08 × 10−4 for Spleen), ATP8B2 (p = 7.53 × 10−7 and FDR = 6.59 × 10−4 for Stomach), PTPN2 (p = 3.96 × 10−6 and FDR = 2.75 × 10−3 for Spleen). This evidence concerns the gene ATP8B2 and juvenile idiopathic arthritis.
