Clinics and Pathology

Disease

myeloid lineage, described in five cases :
  • myelodysplastic syndromes (MDS) to AML-M2 (two cases).
  • De novo acute myeloid leukemia (AML)-M2 (two cases).
  • Agnogenic myeloid metaplasia (AMM) (one case).

    • Epidemiology

    3F/2M, AGE 41-81 yrs (average = 67.8 yrs)

    Prognosis

    Two patients with AML achieved complete remission.

    Cytogenetics

    Additional anomalies

    The four patients with AML had no additional abnormalities; the patient with AMM also had an interstitial deletion of 13q. Metaphase FISH analysis was performed on the AMM patient, using whole chromosome paints for chromosomes 2 and 4. FISH revealed a complex insertion of chromosome 4 into chromosome 2, with resultant 2p23;4q31 fusion and deletion of 2p23->2pter.

    Variants

    Metaphase FISH analysis of one patient with AML also suggested deletion of 2p23->2pter.

    Genes Involved and Proteins

    Note
    Deletion of 2p has been suggested as a recurrent abnormality in AML.
