Study Summary
The purpose of the study is to determine the role of nitric oxide (NO) in asthma. We determine the effect of promoter polymorphisms in the gene for the NO producing enzyme, nitric oxide synthase (NOS2), on exhaled NO in healthy African Americans and Caucasians. We compare exhaled NO levels between African Americans and Caucasians. Information on race or ethnicity, serum samples, blood pressure, exhaled breath condensate and health questionnaires will be collected.
