Immunophenotypic investigation of infant acute myeloid leukemia
Aim of the study – characterization of immunophenotype in infant acute myeloid leukemia (AML). 90 patients (40 boys and 50 girls) with acute leukemia (AL) aged up to 365 days were included in the current study. AML was found more frequently in infants than in older children (26.67 % and 10.83 % resp...

CD61-negativity, high CD99, CD15, CD133 and NG2 expression were immunophenotypic signatures of MLLrearranged infant AML, although CD99 and NG2 had the highest diagnostic efficacy.
