Abstract
Background and Objectives：Genetic factors play a role in the etiology of allergic rhinitis. The glutathione S-transferase (GSTP1)is one of the detoxifying enzymes for oxidative stress. The purpose of this study is to examine Polymorphisms of whether thereis an association between some alleles of GSTP1 genes and allergic rhinitis. Subjects and Method：Patients with allergic rhinitiswere selected on the basis of the following criteria：1) watery rhinorrhea, sneezing, nasal obstruction and/or itching for longer3months and 2) positive reaction at the allergic skin prick test for DP, DF allergen and 3) positive reaction at specific IgE RASTfor DP, DF allergen. GSTP1 gene polymorphisms in exon5 (Ile105Val) were analyzed by polymerase chain reaction (PCR) withrestriction fragment length polymorphisms (RFLP) in 149 patients with allergic rhinitis and 156 healthy control subjects.Results：In allergic rhinitis, Ile105/Ile105 were 106 cases (71.1%), Ile105/Val105 were 42 cases (28.2%), Val105/Val105 were 1case (0.7%) and in normal controls, Ile105/Ile105 were 100 cases (64.1%), Ile105/Val105 were 45 cases (28.8%), Val105/Val105were 11 cases (7.1%)(p=0.004). Conclusion：Genetic polymorphism of Val105/Val105 in GSTP1 may be protective genotypesin allergic rhinitis.
