Cytogenetic/FISH studies were negative for AML panel specific abnormalities, and in our institute we perform the following probes panel: AML-ETO (DC,DF)/t(8;21)(q22;q22), PML-RARA (DC,DF)/t(15;17)(q22;q21), CBFB (DC, BAR)/inv (16)(p13;q22), CEP8/D8Z2, and MLL (DC,BAR)/11q23. The gene discussed is PML; the disease is acute myeloid leukemia.
