title: The association between BsmI variant of vitamin D receptor gene and susceptibility to tuberculosis.
abstract: Vitamin D receptor (VDR) gene variants may play a key role in the susceptibility to tuberculosis (TB). We have investigated the association BsmI, TaqI, FokI polymorphisms in the VDR gene with susceptibility to tuberculosis. This study included 128 patients with TB (pulmonary and extrapulmonary TB) and 80 healthy subjects living in Istanbul, Turkey. Genetic polymorphisms were studied by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniques at genomic DNA isolated from whole blood-EDTA. The present study results indicate that the genotype and allele frequencies for patient group (BB:22, Bb:53, bb:25; B allele:48%, b allele:52%) was significantly different from the control group (BB:6, Bb:48, bb: 46; B allele:30 b allele:70) due to an overrepresentation of B allele (P: 0.000 OR: 1.61 95% 1.23-2.11). However there were no significant differences in distribution of allele/genotype frequencies of FokI, TaqI variants between TB and healthy controls. This study results suggest that BsmI variant of VDR gene may play an important role in susceptibility to tuberculosis.
