Transient myeloproliferative disorder (TMD) is a clonal proliferation of megakaryoblasts, typically occurring in newborns with DS. It is believed that TMD occurs in the presence of GATA-1 mutation together with trisomy 21. The disorder resolved in the majority of patients during the first six months of life, however, 30% of patients can develop acute leukemia or a myelodysplastic syndrome in the first five years of life. In most instances, this unique disorder has the ability to spontaneously “turn off” the overproliferation and enter a state of remission. Only supportive care is recommended for TMD during the first months of life unless the clinical condition requires intervention. This .. View More»
