Transient Myeloproliferative Disorder Blood Study

Biology Study of Transient Myeloproliferative Disorder in Children with Down Syndrome

Protocol Description

This Children’s Oncology Group observational study aims to improve understanding of the natural history of transient myeloproliferative disorder (TMD) and its relationship to subsequent leukemia. TMD is found in babies less than three months old with Down syndrome and is caused by abnormal blood cells that travel throughout the body. This research program will facilitate the development of a TMD cell and protein bank and repository of DNA/RNA from megakaryoblasts for future biological studies and to better understand why some TMD cases develop into leukemia and some don’t.>/p>
