Molecular diversity in AML1/ETO fusion transcripts in patients with t(8;21) positive acute myeloid leukaemia..     ///     Patients with acute myeloid leukaemia with maturation (AML-M2) that carried the t(8;21) were tested for the presence of chimeric AML1/ETO mRNA.     ///    Molecular diversity in the AML1-ETO transcripts will have consequences for the detection of minimal residual disease and antisense studies..
