t(3;21)(q26;q22)

The t(3;21)(q26;q22) translocation is associated with myeloid leukemias and results in a chimeric oncoprotein containing AML1/RUNX1 variably fused to EAP, MDS1, and/or EVI1.

Tumors

- acute myeloid leukemia (AML)

  • post-chemotherapy acute myeloid leukemia (AML)

- chronic myeloproliferative disorders (CMPD)

  • chronic myelogenous leukemia (CML)
    • myeloid blast transformation
