HLA-DQA1 and juvenile idiopathic arthritis: In a more recent study by Hinks and colleagues describing the HLA associations across each JIA category in 5043 JIA cases, 112 of whom had JPsA, diverse associations with HLA alleles and JPsA were found: HLA-DQA1*0401 (p = 0.0001), HLA-DRB1*08 (p = 0.0003), HLA-DQB1*0402 (p = 0.0008), HLA-C*0602 (p = 0.008), and HLA-B*27 (p = 0.003).
