Background: Researchers seek ways to study people s medical problems in order to teach and further general knowledge. The ability to assess and treat people with a wide range of diseases is critical to training people to be good doctors. It is also needed to keep medical staff up to date. In this study, researchers want to study the course of some illnesses to learn more about them. To do this, they will collect and review people s medical records. In some cases, they may also provide treatment. Objective: To collect data that may be used to help researchers create ideas for future research. Eligibility: People age 2 and older who have or are suspected to have a medical condition for which they have been referred to NIH s National Heart, Lung, and Blood Institute, as well as stem cell donors Design: Participants may be screened with a review of the following: Medical records Scans and images Other existing samples and reports. Participants medical data will be collected from the standard care they receive. This includes their routine blood and urine tests, X-rays and scans, and other tests to diagnose or follow their medical condition. Data will also be collected from the treatments they may receive. For stem cell donors, data from apheresis procedures will be collected. Demographic data will also be collected. All of the data will be kept in the medical records or on secure network drives. Some participants may need to be treated for their medical condition. If so, they will sign a separate consent form for that treatment. Participation lasts up to 2 years.
