Clinics and Pathology


acute myeloid leukemia (AML), presenting as a de novo condition or after preceeding myelodysplastic syndrome or exposure to myelotoxic agents

Phenotype stem cell origin

M2/M4 by FAB criteria, frequently with trilineage myelodysplasia: positivity for myeloid markers (i.e. CD13, CD33) as well as for CD117, CD34 and TdT; lymphoid-associated markers tested negative in the reported cases


the frequency of this anomaly in AML is < 1%


the cells may be susceptible to chemotherapy since all reported cases achieved complete remission, despite the presence of other unfavourable prognostic factors


Cytogenetics morphological

the translocation is easy to visualize in G-banded preparations because the dark 7q35 band moves on top of the derivative 1p

Additional anomalies

associated / additional anomalies may include +8 and the classical t(6;9)(p23;q34)

Genes Involved and Proteins

the involved genes are unknown
