Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
After subjects complete the screening process, they will be offered the opportunity to participate in an active research study, or if no appropriate studies are available information and recommendations will be provided for other treatment options.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
The subject carries the diagnosis of a disorder for which the NHLBI has an active research protocol, and based on information received from an outside physician, he/she appears to meet at least preliminary eligibility criteria for that protocol.
OR
The subject is a donor for a subject for which the NHLBI has an active stem cell transplant protocol and based on information received from an outside physician, he/she appears to meet preliminary eligibility as a donor.
OR
The subject is a normal volunteer for which the NHLBI has an active study recruiting healthy normal volunteers and he/she appears to meet preliminary eligibility as a normal volunteer.
Age greater than or equal to 2 and Weight greater than 12 kg. (Healthy Volunteer age greater than or equal to 8)
The subject, the subject s guardian (if the subject is a minor), or the subject s legally authorized representative (LAR) is capable of informed consent, and willing to sign the consent form after initial counseling by clinical staff. Separate consent forms for all interventional or surgical procedures will be obtained after explanation of the specific procedure.
