| Clinics and Pathology |
| Disease | myelodysplastic syndrome (MDS) and acute non lymphocytic leukemia (ANLL) |
| Phenotype / cell stem origin | 1 case of refractory anemia with excess of blastsin transformation (RAEB-t), 1 MDS evolving towards a M4-ANLL, 2 M2-ANLL, and 1 ANLL not otherwise specified |
| Epidemiology | 5 cases to date; 3M/2F, aged 58 yr (median, range: 31-75) |
| Cytogenetics |
| Cytogenetics Morphological | sole anomaly in 2 cases, complex karyotypes in 2 other cases. |
| 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 | AML1 |
| Location | 21q22 |
| 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 |

| Additional cases are needed to delineate the epidemiology of this rare entity: you are welcome to submit a paper to our new Case Report section. |
