Interestingly, PBMCs from RA patients with the rs2230926 TG genotype and rs146534657 AG genotype had a higher A20 expression level compared with RA patients with rs2230926 TT genotype and rs146534657 AA genotype, and a similar finding was reported for T-ALL in our previous study [19]. The gene discussed is TNFAIP3; the disease is acute lymphoblastic leukemia.
