Additional Study Information: The purpose of this study is to identify genetic causes of lung diseases and to develop a research repository so that we can better understand, prevent and treat these conditions. You have been asked to join this study as a healthy control. Even though you do not have lung disease, your sample is valuable to us. For example, you may be related to someone with lung disease or you may have shared a similar environment as someone with lung disease. You will be asked to donate a sample of blood for this study; you may be asked to donate a skin sample or leftover cells/tissue that are removed as part of your medical care. The Clinical Research Coordinator will be able to answer your questions about participating in this study.
