Study of genetic and blood features in Upshaw-Schulman
This study looks at how genetic changes (ADAMTS13 gene mutations) and blood test results relate to symptoms and treatment needs in Upshaw-Schulman syndrome. It may help doctors better predict disease behavior and personalize care.
Oklahoma City, OklahomaAges Any age - NCT01016613Recruiting
Kidney health study that helps build a tissue and data bank
This study collects health information and biological samples to better understand kidney disease and support future kidney research. It may help your care indirectly by improving how kidney conditions are recognized and studied.
Ann Arbor, MichiganAges Any age - NCT01132885Recruiting
Brain scans in children with Williams syndrome
This study uses brain testing—often MRI scans—to learn how the brains of children with Williams syndrome are different from typical development. It may help researchers better describe brain patterns and improve future care for people with Williams syndrome.
Bethesda, MarylandAges 5 years+ - NCT01145196Recruiting
Study drug eye damage and genes in Plaquenil users
This study looks at how Plaquenil (hydroxychloroquine) can harm the retina (the eye’s light-sensing layer) and whether genetics affect who gets affected. You may help by sharing medical details and providing an eye-related blood sample so researchers can compare gene patterns to eye findings.
Bethesda, MarylandAges 18–120 - NCT02362685Recruiting
Metabolic exercise testing study
This study is about doing a breathing-and-heart performance test while you exercise to better understand how your body uses energy. You may join if you’re referred for this type of test and can safely complete it.
BrestAges 5 years+ - NCT02602769Recruiting
Testing blood traits in children with ROHHAD syndrome
This trial studies children with ROHHAD syndrome to better understand their body chemistry and other blood features. The results may help researchers learn what drives the condition and how it might be tracked over time.
Boston, New YorkAges 2–20 - NCT02614911Recruiting
Genetics and health profile study for early severe bowel disease
This study looks at how an early-onset bowel illness looks and what genetic changes may be involved. It may help researchers better understand inherited causes and improve future care for families affected by these conditions.
BordeauxAges Any age - NCT07677072Recruiting
Studying a blood protein to detect hidden bone fragility
This study looks at a protein called lumican in the blood to see if it can help find women who have fragile bones even if their bone density test looks normal. It's for postmenopausal women who are already getting a bone density scan as part of their routine care.
Küçükçekmece, IstanbulAges 45 years+ - NCT01517425Enrolling by invitation
Using blood stem cells to study heart disease traits
This study uses your blood to create special lab cells (induced pluripotent stem cells) to better understand heart-related differences between people with coronary artery disease and generally healthy older adults. It may help researchers learn what biological traits are linked to heart risk and how those traits work.
La Jolla, CaliforniaAges 18 years+ - NCT07414043Recruiting

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 315 recruiting phenotype studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a phenotype trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a phenotype trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
