CD86 and juvenile idiopathic arthritis: Another GWAS study on JIA with a large sample size, including 2751 oligoarthritis and polyarthritis RF-negative patients and 15,886 controls, replicated nine previously reported GWAS loci, and suggested five additional loci with p < 1 × 10−6, i.e., PRR9_LOR, ILDR1_CD86, RNF215, LINC00951, and HBP1, but none of these loci reached genome-wide significance [80].
