Among the four studied SNPs, it has been reported that rs13277113A/G and rs2736340T/C could have a potential eQTL effect on FAM167A and BLK genes in monocytes and lymphoblastic cell lines suggesting that these variants are involved in the physiopathology of RA and SLE (Deng et al., 2013a; Deng et al., 2013b). This evidence concerns the gene BLK and rheumatoid arthritis.
