Infants with Down syndrome (DS) are at a high risk of developing transient abnormal myelopoiesis (TAM). A GATA1 mutation leading to the production of N-terminally truncated GATA1 (GATA1s) in early megakaryocyte/erythroid progenitors is linked to the onset of TAM and cooperated with the effect of trisomy 21 (Ts21). To gain insights into the underlying mechanisms of the progression to TAM in DS p...
