Analysis of Vitamin D Receptor Polymorphisms in Patients with Familial Multiple Sclerosis

چکیده
Objective Genetic and environmental factors are important in the development of the multiple sclerosis (MS). Vitamin D shows its effects on the immune system with the vitamin D receptor (VDR) in the nucleus. Single nucleotide polymorphisms (SNPs) in the VDR gene can lead to alterations in vitamin D functions and metabolism.Taq I, Apa I, Fok I and Bsm I polymorphisms and MS associations have been investigated in many studies. VDR gene polymorphism has not been previously studied in patients with familial MS. Aim We aimed to investigate the relationship between familial MS patients present in Turkish population and VDR genotypes Taq I, Apa I and Fok I polymorphisms. Methods 29 patients with a family history of MS and 120 healthy control subjects were included in the present study. We studied present VDR genotypes Taq I, Apa I and Fok I polymorphisms. Results We observed a significant difference between controls and patient group only in Taq I polymorphism (p: 0.025). Homozygousity of G allele was not seen in the patients whereas in controls frequency of that genotype was p:0.208. When gender was considered males show significant difference for GG genotype. There were no significant association for the Apa I and Fok I polymorphisms. Conclusion Although our findings suggest association between VDR Taq I polymorphism and the familial MS, additional studies are needed to establish detailed relationships.

The Association of Vitamin D Receptor Gene BsmI Polymorphism with Multiple Sclerosis in Iranian Patients
Background & Aims: 1,25-dihydroxyvitamin D3 (1,25 (OH)2 D3), the biologically active form of vitamin D, exerts an immunosuppressive effect through binding to its specific nuclear receptor. The present case-control study was done to examine the possible association of BsmI polymorphism in vitamin D receptor gene (VDR gene) with severity of multiple sclerosis (MS). Methods: 267 Iranian patients w...

Objective(s): Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS) with unknown etiology. Various genetics and environmental factors contribute to the pathogenesis of the disease. The interleukin-7 receptor alpha chain (IL-7Ra) was identified as the first non-major histocompatibility complex (non-MHC) MS susceptibility locus. In this study we are tr...

Effect of Vitamin D treatment on Interleukin-2 and Interleukin-4 Genes expression in Multiple Sclerosis
Introduction: Multiple sclerosis is a chronic inflammatory disease of central nervous system. The etiology of MS is slightly known, but genetic and environmental factors are reported. Vitamin D regulates gene expression and affects target cell functions. The aim of this study was to investigate the expression variation of IL-2 and IL-4 genes under vitamin D supplementation in patients with mult...

Aim and Background: Multiple sclerosis (MS) is an autoimmune inflammatory disease that attacks myelinated axons in the central nervous system (CNS) resulting in destroying the myelin and the axon. According to high prevalence of disease in Iran, it needs to study different aspects of disease including factors influencing the pathogenesis and the other risk factors. Various type of genetic varia...
