Abstract: Leukemia compared to the general population, with a higher occurrence of myeloid leukemia. Although patients with Down syndrome and myeloid leukemia are known as a subtype with a good prognosis, those who relapse face an unfavorable outlook. Acute lymphoblastic leukemia in DS is considered to have a poor prognosis. The relapse rate for this combination, compared to their peers without DS, is considered high. Today, we have a better understanding of the mutational spectrum of leukemias associated with DS. Studies using models based on embryonic stem cells, induced pluripotent stem cells, and animal models have shed light on the mechanism by which these mutations contribute to the initiation and progression of the disease. In this chapter, we list the biological knowledge, as well as the treatment strategies currently available for DS-associated leukemias. We focus on the mechanisms of leukemia initiation and progression in children with DS and highlight new molecular targets with greater success in preclinical trials that have the potential to advance to the clinic.
