Clinics and Pathology

Disease Myelodysplastic syndromes (MDS) and acute myeloid leukemias (AML) and therapy related AML
Phenotype / cell stem origin M1 or M2 AML
Etiology 11 of 15 cases have had treatment for a previous malignancy (treatment related MDS or AML (t-MDS/AML)). Previous disease was a breast cancer in 5 cases, a hematologic malignancy in 4.
Epidemiology 15 available cases at least, sex ratio: 2M / 13F; mediane age around 50 yrs (range <15 - 62)
Clinics blood data: pancytopenia
Prognosis poor

Cytogenetics

Additional anomalies + 8 found in 7 of 15 cases

Genes involved and Proteins

Gene NameCBFA2T3 (core-binding factor, runt domain, alpha subunit 2; translocated to, 3)
Location 16q24.3
Protein member of the ETO (MTG8) family
Gene NameRUNX1 (runt-related transcription factor 1 (acute myeloid leukemia 1; aml1 oncogene))
Location 21q22.12
Dna / Rna transcription is from telomere to centromere
Protein contains a Runt domain and, in the C-term, a transactivation domain; forms heterodimers; widely expressed; nuclear localisation; transcription factor (activator) for various hematopoietic-specific genes.

Result of the chromosomal anomaly

Hybrid gene
Description 5' AML1 - 3' CBFA2T3
  

To be noted

Case Report A case of trisomy 8 and loss of the Y-chromosome as secondary aberrations in a ten year old boy with de novo AML FAB M2 and t(16;21)(q24;q22)
