BACKGROUND: Behçet's disease (BD) is an inflammatory disorder characterized by oral aphthous lesions, uveitis, and genital ulcerations. The vitamin D receptor (VDR) has a crucial role in the pathogenesis of this disease because it mediates the functions of vitamin D in the immune system. Alterations of VDR expression related to polymorphic alleles of the VDR gene may play a pathogenic role in BD and BD's clinical presentations.
METHODS: 150 BD patients and 150 healthy controls were included and genotyping was carried out by polymerase chain reaction/restriction fragment length polymorphism.
RESULTS: Significant differences between patients and controls in rs1544410, rs2228570, and rs731236 genotypes were observed (respectively, p = 0.04, p = 0.007, p = 0.012). The clinical characteristics of BD patients were evaluated and patients with ocular lesions had a higher percentage of rs1544410 A alleles (p = 0.004), and patients with oral aphthous lesions, a positive pathergy tests, and arthritis had more rs2228570 C alleles than patients without these clinical findings (respectively, p < 0.001, p = 0.021, p = 0.045).
CONCLUSION: VDR gene polymorphisms may possibly have a role in the pathogenesis of BD through their effects on VDR expression and may be associated with the increased risk of several clinical findings.
