                            <p>The frequency hematological malignancies is increased in patients with Down syndrome as a result of transient abnormal myelopoiesis. Although transient myeloproliferative disease may regress spontaneously without treatment, myeloid leukemia may develop in 30% of cases. GATA1 mutation can be detected in trizomic cells on chromosome 21, which are spesific to leukemias seen in Down syndrome. In this article, we present a case of transient myeloproliferative disease that developed as a result of GATA1 mutation in a newborn with Down syndrome.</p></trans-abstract>
