Gene mutation study aims to unlock blood cancer mysteries
NCT ID NCT07019155
First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 2 times
Summary
This study follows people with a gene change (DDX41) that raises the risk of blood cancers like MDS and AML, along with their family members. Researchers will collect health information and samples over 10 years to learn how these inherited risks lead to cancer. No treatment is given; the goal is simply to observe and understand the disease process.
