This study follows people with myelodysplastic syndromes (MDS) for up to 20 years to understand how the disease changes over time. Researchers will collect blood, bone marrow, and other samples from 1,100 participants, including healthy donors. The goal is to learn more about MDS…

This study follows 306 adults with certain DNA changes in their blood cells (called CHIP or CCUS) to see how these changes affect health over time. Researchers want to learn if these changes increase the risk of blood cancers or heart problems. Participants will have yearly check…

This study looks at genetic changes in people with early-stage blood cancers or conditions that may lead to cancer. Researchers will analyze blood, bone marrow, or cheek cell samples from up to 10,000 participants to find DNA errors linked to cancer risk and progression. The goal…

This study is a large registry that collects health information from up to 200,000 people with blood disorders such as hemophilia, thrombosis, and sickle cell disease. Participants are seen at Hemophilia Treatment Centers across the U.S. The goal is to gather real-world data to h…

This study follows 2,000 people who have had ovarian or other solid cancers to learn why some later develop blood cancers like leukemia. Researchers will look at genetic changes in blood cells and treatment history to identify risk factors. No new treatments are being tested—the …

This study looks at whether firefighters' exposure to hazardous chemicals leads to pre-cancerous changes in their blood. Researchers will collect blood samples from 300 firefighters aged 40-49 with at least 5 years on the job. The goal is to find early markers that might predict …

This study will analyze the genes of 25,000 adults who have cancer or are at risk for it. Researchers will use advanced testing to find genetic changes linked to cancer and track health records over time. The goal is to learn more about cancer biology and discover new ways to per…

This study collects bone marrow from 24 adults aged 65+ having hip surgery to understand how common aging-related blood cell mutations (called CHIP) change cell metabolism. Researchers will compare gene activity in mutated versus normal stem cells. The goal is to learn more about…

This study looks at how gut bacteria and the immune system interact in children and adults receiving stem cell transplants or CAR-T therapy. Researchers will collect stool and blood samples over time to find patterns linked to complications like infections or graft-versus-host di…
