Clinics and Pathology

Disease acute myeloid leukemia (AML) secondary to toxic exposure
Note only one case, but with features identical to 2 other cases: one case of t(1;21)(p36;q22), and one case of t(19;21)(q13.4;q22)
Phenotype / cell stem origin M2-AML
Etiology about 50 years after radiation exposure from nuclear explosion
Clinics pancytopenia preceeded leukemia
Evolution complete remission was obtained and the patient returned to the previous pancytopenia; subsequent relapse occurred

Genes involved and Proteins

Note the gene involved in 18q21 is unknown
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

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
