| Outline of Final Research Achievements |
To reveal the mechanism of the development from transient abnormal myelopoiesis (TAM) to acute megakaryoblastic leukemia (AMKL) in neonates with Down syndrome (DS), we performed gene mutation analysis for blood of DS neanates using the next generation sequencing. Of 39 neonates with DS, 27 developed TAM. Out of them, 18 (67%) had GATA1 gene mutation in their blood. Out of 30 children with DS-AMKL, 26 (87%) had GATA1 gene mutation. In adiition, JAK3, p53, and RAD21 gene mutations were found in 3 children each.
