Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals aged 2 to 100 with suspected genetic diseases affecting the heart and/or blood vessels, as well as their relatives.

Probably not a fit

Patients who are healthy volunteers unable to provide informed consent or who decline to participate in sample collection may not benefit from this study.

What this trial studies

This observational study aims to investigate the etiology and natural history of rare and orphan diseases with vascular phenotypes. It involves collecting data and biological specimens from individuals aged 2 and older who may have genetic conditions affecting their cardiovascular system, as well as their family members and healthy volunteers. Participants will undergo a series of assessments, including medical history reviews, physical exams, imaging tests, and sample collections. The findings may lead to the identification of novel disease mechanisms and potential future therapeutic studies.

Why it matters

Potential benefit: If successful, this research could enhance understanding of rare genetic diseases and improve diagnosis and treatment options for affected patients.

How similar studies have gone: Other studies focusing on the genetic basis of rare diseases have shown promise, suggesting that this approach may yield valuable insights.
