The aim of this study is to determine the roles of eNOS gene variations in BCA development. Our study included 91 patients diagnosed with BCA and 91 healthy controls. eNOS 4VNTR (4a/b), T786C and G894T gene variations genotype distributions were determined by PCR and RFLP methods. The significant difference was determined between these groups in terms of eNOS T786C and eNOS G894T gene variations genotype distributions ( p  < 0.05). TT genotype for G894T gene variation and CC genotype for T786C gene variation were detected higher in patients. The CC genotype of T786C gene variation was detected significantly higher in male patients than in male controls ( p  < 0.05). In addition, aa-TT, ab-TT, bb-TT haplotypes of 4VNTR (4a/b)-G894T gene variations, aa-CC, ab-CC, bb-CC haplotypes of 4VNTR (4a/b)-T786C gene variations and TT-TT, TT-CC, TT-CT, GG-CC, GT-CC haplotypes of G894T-T786C gene variations were observed in patient group more than control group. The significant difference was detected between these groups in terms of eNOS (G894T-T786C) haplotypes ( p  < 0.05). In our study, eNOS T786C and eNOS G894T gene variations were determined important genetic risk factor in the Thrace population of Turkey.
