Objectives. In our study we aimed to determine VDR gene polymorphisms in patients with Behcet's disease (BD) and neuro-Behcet's disease (NBD) in Turkish population. Methods. PBL obtained from 37 patients with BD, 21 patients with NB, and 30 healthy controls were investigated. Genomic DNA was extracted from whole blood using the QIAamp Blood Kit. VDR ApaI (rs7975232), VDR FokI (rs2228570), and VDR TaqI (rs731236) genotyping was performed by real-time polymerase chain reaction with SimpleProbe melting-curve analysis. Results. The allelic and genotype distributions of FokI and TaqI polymorphisms were not different among Behcet's disease, neuro-Behcet's disease, and control subjects in Turkish population (p > 0.05). Only the frequency of ApaI A allele in control is higher than that in BD (60% versus 38.5%), and the p value is 0.014, but the power is not enough to conclude that ApaI A allele is protective in BD in our study. Taken together, we found no significant differences between the BD, NBD, and control groups regarding the distribution of ApaI, TaqI, and FokI genotype and alleles frequencies. Conclusions. Future studies with larger patients' numbers may show differences between VDR polymorphisms and Behcet's disease.
