ABSTRACT
We describe a very rare case of 6.9-year-old boy with Down syndrome (DS) and a prior history of transient myeloproliferative disorder. He was diagnosed with acute megakaryoblastic leukemia and found to have a novel GATA1 gene mutation, as well as a complex karyotype without recurrent acute myeloid leukemia (AML) aberrations. The patient achieved an early bone marrow response to chemotherapy. However, relapse occurred during treatment, 9 months after the initial diagnosis. Although GATA1 mutations are closely associated with DS-AML, we speculate that factors other than the presence of the GATA1 mutation can affect the overall outcome in older pediatric patients.
