TNF and Takayasu arteritis: In this study, we looked for a possible association between the polymorphisms in the IL-10 −1082 A/G (rs1800896), IL-10 −819 C/T (rs1800871), IL-10 −592 A/C (rs1800872), TNF-α −238 A/G (rs361525), TNF-α −308 A/G (rs1800629), IFN-γ −179 G/T (rs2069709), IFN-γ −155 G/A (rs2069710), TGF-β −509 T/C (rs 1800469) and TGF-β 29 T/C (rs1800470) genes and the development of Takayasu’s arteritis.
