Overexpression of CD123 correlates with the hyperdiploid genotype in acute lymphoblastic leukemia.

Abstract excerpt

We evaluated CD123 expression in 95 pediatric and 24 adult ALL patients and compared the results with the CD123 expression in normal B-cell precursors. Early B-cell precursors were negative while intermediate precursors and mature B cells showed weak CD123 expression. Leukemic blasts in 31% of precursor-B ALL samples exhibited strong expression of CD123, 61% had moderate CD123 expression and 8% were negative;...
