Abstract

NAT2 plays a critical role in external chemical detoxification. Thus, polymorphism of NAT2 has been suggested to associate with several disorders. A number of studies have been devoted to the relationship between NAT2 polymorphism and asthma risk. However, the results were inconclusive. In this study we aimed to derive a more precise estimation of the association. A literature search in the common databases was conducted and then meta-analyses evaluating the association of NAT2 polymorphism and asthma risk were performed. Eligible studies were identified for the period up to May 2013. A total of five case–control studies containing 946 cases and 1,091 controls were lastly included for analysis. The overall data showed that slow acetylators of NAT2 might have an association with increased asthma risk (OR 2.20; 95 % CI 1.31–3.72). The pooled data suggest that slow acetylators of NAT2 might contribute to asthma risk among Caucasians. Future studies are needed to confirm this conclusion.
