In this case report of a child with mosaic T21 and DS-AMKL, flow cytometry performed on BMA showed no immunophenotypic abnormalities, morphological review of BMA revealed no clusters of tumor cells, and BMA failed to show the expected GATA1 mutation. This case suggested that chromosomal alterations may precede morphological, flow cytometric and clinical changes and accelerate progression of the disease.
