The disease is also characterized by infiltration of lymphocytes and neutrophils into the affected tissues. Because cytokines are involved in the regulation of lymphocyte and phagocyte functions, they may play an important role in the pathogenesis of Beh\u00e7et's disease. Leptin, a member of the gp 130 family of cytokines, induces a strong T\u2010helper 1 response and is regarded as a proinflammatory inducer. Recent studies have shown that serum leptin concentration was increased in patients with Beh\u00e7et's disease and correlated with disease activity.<\/jats:p><jats:p><jats:bold>Objectives\u2002<\/jats:bold> We aimed to investigate the role of G2548A polymorphism of leptin gene in patients with Beh\u00e7et's disease and compare the results with healthy controls.<\/jats:p><jats:p><jats:bold>Patients and methods\u2002<\/jats:bold> A total of 93 subjects with Beh\u00e7et's disease and 125 healthy controls were included in this study. Analyses of G\u20102548A polymorphism of the <jats:italic>LEP<\/jats:italic> gene were performed using the PCR\u2010restriction fragment length polymorphism technique. The genotypes (GG, GA, and AA of leptin G2548A) and alleles (G and A of leptin 2548) were scored and the frequency was estimated. The frequencies of the alleles and genotypes in patients and controls were compared. We analysed the correlation between leptin gene polymorphism and the clinical features of BD.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> Both genotype and allele frequencies were not significantly different between controls and Beh\u00e7et's disease patients [OR\u00a0=\u00a00.67, 95% CI (0.35\u20131.29), <jats:italic>P<\/jats:italic>\u00a0=\u00a00.197 and OR\u00a0=\u00a00.77, 95% CI (0.52\u20131.15), <jats:italic>P<\/jats:italic>\u00a0=\u00a00.184]. We did not find any significant relationship between leptin gene polymorphism and the clinical features of BD (<jats:italic>P<\/jats:italic>\u00a0&gt;\u00a00.05).<\/jats:p><jats:p><jats:bold>Conclusion\u2002<\/jats:bold> In the present case\u2010control study, we found no evidence of an association between the G\u20102548A variant of the leptin gene and BD among Turks. Further studies are needed to investigate serum leptin level to explain the mechanisms behind the lack of association between leptin G2548A gene polymorphism and
