    Abstract:
    BACKGROUND: Multiple sclerosis (MS) is a chronic, demyelinating disease of the central nervous system (CNS). Genetic and environmental factors are important in disease development. Many studies have investigated the relationship between MS and VDR polymorphisms. VDR gene polymorphism has not been previously studied in Turkish MS patients. We aimed to investigate the relationship between MS and VDR genotypes Taq I, Apa I and Fok I polymorphisms in a Turkish population. METHODS: 167 MS patients and 146 healthy control subjects were included in the present study. MS and the VDR TaqI (rs731236), ApaI (rs7975232), and FokI (rs2228570) polymorphisms were investigated. RESULTS: The study enrolled 167 patients (121 females, 46 males) with MS and 146 healthy individuals (88 females, 58 males). The frequency of only the Fok I polymorphism differed significantly between the two groups (p = 0.002). The TaqI (rs731236) and ApaI (rs7975232) genotype distributions were not significantly different between MS patients and healthy controls (p = 0.626 and p = 0.990, respectively). Also there were no significant gender difference between patients and controls for Taq I and Apa I. CONCLUSION: In conclusion, we found a significant association between MS and the FokI polymorphism in our region of Turkey. However, the results may be different in other populations. More epidemiological and genetic studies are needed to explain the association between genetic factors and MS.
