Asthma is a complex, heritable disease that affects more than 11.2% of the U.S. population, which represents approximately 9 million children and 23 million adults. Although the underlying characteristics of asthma exist in virtually all patients, the clinical expression of the disease and response to treatment are highly variable. The purpose of this study is to identify characteristics of participants who have difficult to treat asthma and those who have easy to treat asthma. It is hoped that this study will provide information about these characteristics that will lead to better and improved treatment for individuals with asthma.
