Clinics and Pathology

Disease

myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML)

Phenotype stem cell origin

1 case of refractory anemia with excess of blastsin transformation (RAEB-t), 1 MDS evolving towards a M4-AML, 2 M2-AML, and 1 AML not otherwise specified

Epidemiology

5 cases to date; 3M/2F, aged 58 yr (median, range: 31-75)

Genes Involved and Proteins

Note
The gene in 5q13 is yet unknown, and, because cryptic t(12;21) ETV6 /AML1 are not rare, it is therefore uncertain whether this translocation involve a new AML1 partner
Gene name
RUNX1 (runt-related transcription factor 1 (acute myeloid leukemia 1; aml1 oncogene))
Location
21q22.12
Dna rna description
transcription is from telomere to centromere
Protein description
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
