- Abstract
Neonates with Down syndrome (DS) are predisposed to developing transient abnormal myelopoiesis (TAM) and acute myeloid leukemia (AML) associated with DS. However, there is a paucity of data on hematological aberrations and GATA1 mutations in neonates with DS in East Asian populations. Total 109 patients with DS who had one or more CBCs obtained were enrolled. The molecular analysis of the GATA1 gene performed in 10 patients (three TAM, three AML associated with DS at diagnosis, one remission case of AML associated with DS and three DS without TAM or AML). East Asian DS neonates showed low frequency of thrombocytopenia, uncommon neutrophilia and higher prevalence rate of TAM compared to previous reports from western countries. GATA1 mutations were identified in almost all TAM and AML associated with DS samples, but were not detected in the samples from DS without TAM or AML associated with DS. East Asian DS neonates and children showed distinctive spectrum of hematological abnormalities.
