TNFSF4 and rheumatoid arthritis: We found that rs181758110 in the promoter region of the TNFSF4 gene was associated with RA, and no SNPs of the TNFSF4 gene were associated with the characteristic autoantibodies of RA, which denotes that rs181758110 of the TNFSF4 gene may not be a major SNP that contributed to the pathogenesis of RA.
