Allogeneic Hematopoietic Stem Cell Transplant for GATA2 Mutations

Summary

Background: \- GATA2 deficiency is a disease caused by mutations in the GATA2 gene. It can cause different types of leukemia and other diseases. Researchers want to see if a stem cell transplant can be used to treat this condition. A stem cell transplant will give stem cells from a matching donor (related or unrelated) to a recipient. It will allow the donor stem cells to produce healthy bone marrow and blood cells that will attack the recipient s cancer cells. Objectives: \- To see if stem cell transplants are successful at treating GATA2 mutations and related conditions. Eligibility: \- Recipients who are between 6 and 70 years of age and have GATA2 deficiency. Design: * All participants will be screened with a physical exam and medical history. Blood samples will be collected. Recipients will have imaging studies and other tests. * Recipients will have chemotherapy or radiation to prepare for the transplant. On the day of the transplant, they will receive the donated stem cells. * Recipients will stay in the hospital until their condition is stable after transplant. * Frequent blood tests and scans will be required for the first 6 months after the transplant, followed by less frequent visits over time.
