Participants will be asked to provide their permission to share their de-identified (coded) information with other registries and databases. This information may be used for retrospective research or to plan for clinical trials. Participants will be asked to allow the Foundation investigators to review this information to determine if the participants may be eligible for participation in future research studies being conducted by secondary investigators (not affiliated with the Foundation). Interested Registry participants contacted for possible participation in future research studies being conducted by secondary investigators will undergo a separate informed consent process for each such research study.
