| Clinics and Pathology |
| Disease | ANLL mostly; occasionally: CML-like cases without t(9;22), or CML in blast crisis (with t(9;22)) |
| Phenotype / cell stem origin | M2 or M4 ANLL mainly; involving maturing leukemic cells in ANLL cases, might affect trilineage progenitors in CML-like cases |
| Epidemiology | most cases have been found in Japan; balanced sex ratio |
| Cytology | auer rods; low alkaline phosphatase scores; CML like blood features |
| Prognosis | CR in most cases; but patients tend to relapse; mean survival: 15 mths |
| Cytogenetics |
| Additional anomalies | most often (90%) none |
| Genes involved and Proteins |
| Gene Name | HOXA9 |
| Location | 7p15 |
| Protein | encodes a class I homeodomain protein potentially involved in myeloid differentiation |
| Gene Name | NUP98 |
| Location | 11p15 |
| Dna / Rna | alternate splicings |
| Protein | contains repeated motifs and a RNA binding motif; nucleoporin: role in nucleo-cytoplasmic transport |
| Result of the chromosomal anomaly |
| Description | 5' NUP98 - 3' HOXA9 |
| Description | fuses the N-term GLFG repeat domains of NUP98 to the HOXA9 3' homeobox |
| Oncogenesis | may promote leukaemogenesis through inhibition of HOXA9-mediated terminal differentiation and/or aberrant nucleocytoplasmic transport |
