IL10 and diffuse large B-cell lymphoma: In this study, we demonstrated that in our Jordanian Arab population the risk of DLBCL is not influenced by any of the polymorphisms affecting either the proximal (rs1800872A > C, rs1800890A > T, rs1800896T > C) or the distal (rs1800871G > A) region of the IL-10 promoter gene (p = 0.81, 0.43, 0.78, and 0.76; respectively).
