BACKGROUND AND OBJECTIVES: Identification of STRK1 locus by the deCODE group followed by the discovery of phosphodiesterase 4D (PDE4D) gene in strong association with ischemic stroke patients has provided useful insights toward understanding the genetic etiology of the disease. In this study, we aimed at investigating the association between 3 polymorphisms of the PDE4D gene and ischemic stroke in the Pakistani population. METHODS: Three polymorphisms in PDE4D gene were analyzed in 200 patients of ischemic stroke and 250 controls of Pakistani origin using polymerase chain reaction-restriction fragment length polymorphism method. Data were coded and entered in SPSS Windows (version 12.0). Odds ratios and 95% CIs were calculated using multivariate logistic regression analysis. RESULTS: Marker SNP83(rs966221) was found significantly associated with ischemic stroke on univariate and multivariate analysis (P<0.005; odds ratio, 1.64 [1.13 to 2.40]). Haplotype analysis for markers in linkage disequilibrium failed to show any association with the disease. CONCLUSIONS: The association of PDE4D variation with ischemic stroke extends to the Pakistani population and supports a role for phosphodiesterases in stroke pathogenesis.
