Recent studies imply the effects of micronutrient intake on the development of several cancers including primary brain cancer (PBC). The biological effects of vitamin D, a member of the fat-sol-uble vitamin family acting as a steroid hormone, was carried out by binding its receptor (VDR) through vitamin D-binding-protein (VDBP). The present study aims to investigate the effects of vitamin D levels and VDR rs2228570, VDR rs731236, VDBP 7041 poly-morphisms on PBC development. The study group consisted of 71 patients and 84 controls. Vitamin D levels were determined by high-pressure liquid chromatography where polymorphisms by polymerase-chain-reaction and restriction fragment length polymorphism methods. The distribution of VDR rs2228570 variants in PBC and its subgroups were determined as FF>Ff>ff; VDBP rs7041 variants were TG> GG>TT, however, VDR rs731236 variants were Tt>TT>tt in PBC and meningioma and TT>Tt>tt in glioma. Vitamin D levels were measured below normal levels in all patients and control groups, which shows the deficiency in Turkish society in line with the literature. Our results show that low serum vitamin D level may be an individual risk factor in the development of brain tumors, however, VDR rs2228570 and rs731236 and VDBP rs7041 polymorphisms have no effect on the risk of disease development.
