Allogeneic Hematopoietic Stem Cell Transplant for Patients With Mutations in GATA2 or the MonoMAC Syndrome
National Cancer Institute (NCI)
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.
Description
Background: Genetic and sporadic mutations on one allele of the GATA2 gene lead to a syndrome termed MonoMAC. MonoMAC is characterized by: 1) infections with Mycobacterium avium complex (MAC) and other opportunistic infections, 2) deficiency of monocytes, B-lymphocytes, and Natural Killer (NK) cells in the peripheral blood, and 3) progression to myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia (CMML), and acute myelogenous leukemia (AML), and 4) mutations on one allele of GATA2 in most participants. We propose to evaluate the efficacy and safety of allogeneic hematopoietic stem…
