In the case of rheumatoid arthritis (RA), one meta-GWAS found no association between the CD247 gene and RA at a genome-wide significance level [6]; however, a more recent meta-analysis of GWAS data from RA and celiac disease (CeD) identified CD247 as a novel susceptibility locus for both diseases [7]. This evidence concerns the gene CD247 and rheumatoid arthritis.
