Objective: The aim of the present study was to investigate any possible association between the macrophage migration inhibitory factor (MIF) -173GC variant and Behçet's disease (BD) in a group of Turkish patients. Subjects and Methods: A total of 111 patients with BD and 100 healthy controls were enrolled in this study. Genomic DNA was extracted from peripheral lymphocytes. The MIF -173GC variant was genotyped using polymerase chain reaction restriction fragment length polymorphism. The allele and genotype frequencies of patients and controls were compared using the ?2 test. Results: A statistically significant difference in the distribution of the genotype was observed between BD patients and healthy controls. The homo-genotype CC was more prevalent in the patient group compared to the control group (p = 0.008, OR: 0.24, 95% Cl: 0.05-0.78). A significant association was observed when the patients were compared with the controls according to GG + GC versus CC ge-notypes (p = 0.003, OR: 1.21, 95% CI: 0.06-0.063). Allele frequencies of the MIF -173GC variant did not show any statistically significant difference between patients and controls. Conclusion: In this study, we conclude that the CC ge-notype of the MIF -173GC variant may be a risk factor in the pathogenesis of BD in the Turkish population. However, further studies with larger samples are needed to address the exact role of this variant in BD. © 2018 The Author(s) Published by S. Karger AG, Basel.
