CCL18 and rheumatoid arthritis: Seventeen consensus genes arose (they were defined as being part of both extreme priority lists obtained using the genes ranked in the top 1% when either /τ2 is as initially estimated or when /τ2 is set to 100): ABCF1, AGER, AIF1, BACE2, C2, CAPG, CCL1, CCL18, CD40, CDKN1A, DOCK2, L3MBTL4, NEBL, NFX1, RND3, RPS19, and TNXB. The list generated is unlikely to be random because it contains at least four genes reported to be associated with RA.
