WT1 and acute myeloid leukemia: Two assays are currently available: multiparametric flow cytometry (MFC) on the leukemia associated immunophenotype (LAIP) and quantitative RT-qPCR on genes known to be mutated or over-expressed in a subgroup of AML (e.g. FlLT3-ITD, NPM1 mutation, CBF-fusion transcripts, WT1 gene,...) (4, 5).
