| Identity |
 | |
| t(3;5)(q25;q34) (R-banding) - Courtesy Jacques Boyer | |
| Clinics and Pathology |
| Disease | myeloproliferative disorders (MPS), myelodysplastic syndromes (MDS), and acute non lymphocytic leukemia (ANLL) |
| Phenotype / cell stem origin | M2, M4, M6 ANLL; trilineage involvement |
| Epidemiology | median age: 35 yrs; balanced sex ratio |
| Prognosis | CR: 8/12, but median survival is less than 1 yr |
| Cytogenetics |
| Cytogenetics Morphological | The breakpoints (3q25 and 5q34) have been controversial for a long time. |
| Additional anomalies | most often none; +8 |
| Genes involved and Proteins |
| Gene Name | MLF1 |
| Location | 3q25 |
| Protein | 31 KDa; widely expressed; cytoplasmic localisation; possible role in normal hematopoietic differentiation |
| Gene Name | NPM1 |
| Location | 5q34 |
| Protein | nuclear localisation; binds to single and double strand nucleic acids; phosphoprotein that may transport ribonucleoproteins; may also have a role in DNA replication nuclear phosphoprotein; role in centrosome duplication and various relations with other proteins like p53, ARF, ... (numerous interations are under study). |
| Result of the chromosomal anomaly |
| Description | 5' NPM-3' MLF1 on der(5) |
| Description | 54 kDa with the 175 N-term Amino acids from NPM |
