OBJECTIVE: The purpose of this study was to verify the association between the Trp 64 Arg polymorphism and idiopathic overactive bladder (OAB) syndrome. STUDY DESIGN: A case-control study was conducted with 218 women. The case group consisted of 49 patients with OAB symptoms; the control group included 169 women without urinary symptoms. The studied polymorphism was detected by restriction fragment length polymorphism analysis. The χ(2) test was used to compare categoric data, with a significance level of 5%. Numeric data were compared with the use of the parametric t test or nonparametric Mann-Whitney U test. RESULTS: The distribution of the polymorphism in the investigated women was digested homozygous T allele 69.75%, heterozygotes 29.8%, and homozygous A allele 0.45%. A comparison between the groups showed higher prevalence of the digested homozygous T allele genotype in women with OAB syndrome (P = .001). Multiple logistic regression analysis identified that a family history of OAB syndrome was an independent risk factor for OAB syndrome. CONCLUSION: The Trp 64 Arg polymorphism was associated with OAB syndrome in the Brazilian population.
