Introduction: In this study, we investigated the etiopathogenesis of allergic rhinitis by analyzing the polymorphisms including GPx-1 Pro198Leu, CAT-262 C/T, and MnSOD Ala16Val. Methods: The diagnosis of allergic rhinitis was diagnosed by clinical history, examination, serum total immunoglobulin E levels and skin prick test. Five mL of peripheral blood from patients and individuals constituting the control group was taken into EDTA tubes. DNA isolation from whole blood samples was performed according to the Poncz method. Results: Because of this study; for the Pro198Leu polymorphism of the GPX1; was concluded with 95% confidence that the presence of the Leu allele increased the susceptibility to allergic rhinitis 1.092 times. However, this increase was not found to be statistically significant. For the -262 C/T polymorphism of the CAT gene; was concluded with 95% confidence that the presence of the T-allele increased the susceptibility to allergic rhinitis 27,064 times. This increase was found to be statistically significant. For Ala16Val polymorphism of the Mn-SOD gene; was concluded with 95% confidence that the presence of the Ala allele increased the susceptibility to allergic rhinitis 25,791 times. This increase was found to be statistically significant. Conclusion: A significant relationship was found between allergic rhinitis and the genotypes and the frequencies of alleles in the polymorphisms of the MnSOD and CAT genes. However, no significant relationship was found between allergic rhinitis and the polymorphisms of the GPx-1 gene.
