Abstract :The aim of this study is to evaluate the association of interleukin-4 (IL-4) gene intron 3 and interleukin-1 receptor antagonist (IL-1Ra) gene intron 2 variable number tandem repeat (VNTR) polymorphisms with bladder cancer (BC) susceptibility in Turkish population. A total of 75 BC patients and 126 healthy controls were included in this case-control study. Genotyping for the interested polymorphisms were analyzed through polymerase chain reaction (PCR). The strength of association between both IL-4 and IL-1Ra gene VNTRs and BC susceptibility was estimated utilizing odds ratio (OR) with corresponding 95% confidence interval (CI). In the study, no statistically significant differences were determined in the allele distributions for either in IL-4 gene intron 3 VNTR (OR= 1.33; CI 0.704-2,41, p=0.390) or in IL-1Ra gene intron 2 VNTR polymorphisms (OR= 0.890; CI 0.569-1.394, p=0.346) between BC patients and control groups. The genotype distributions of IL-4 gene were estimated for RP1/RP2 (OR= 1.55; CI 0.11-7.74, p = 0.590) and RP1/RP1 (OR= 2.08; CI 0.48-9.06, p = 0.320), found no difference between BC and control groups. The genotype distributions of IL-1Ra gene were estimated for 2L (OR= 1.401; CI 0.753-2.610, p = 0.287) and 22 (OR=0.908; CI 0.252-3.276, p = 0.883) and found no difference between BC and control groups. This study suggest that there were no statistically significant differences determined either in genotype or allele distributions between BC patients and control groups for both IL-4 intron 3 VNTR and IL-1Ra intron 2 VNTR polymorphisms in Turkish population and therefore there was no association of these variants with BC risk in this population.
