disorder Behcet's disease is a multi-systemic vascular, and its pathological origin is
unknown. Genetic factors that predispose individuals to Behcet's disease (BD) are
considered to play an important role in the development of the disease. The serum level of
tumor necrosis factor (TNF) is elevated in patients with BD. The aim of this meta-analysis
was to assess the association between TNF gene polymorphisms and BD.
