| Disease | Acute leukemias |
| Note | poorly known: only 3 cases to date |
| Phenotype / cell stem origin | 1 case of M0 acute non lymphocytic leukemia (ANLL), 1 case of M4 ANLL, and 1 case of acute lymphoblastic leukemia (ALL) |
| Epidemiology | a 76 yr old female patient, a 81 yr old male patient, and a 69 yr old male patient |
| Prognosis | unknown |
| Cytogenetics |
| Cytogenetics Morphological | The t(1;2) presented as a der(2)t(1;2) in at least 2 of the 3 cases, resulting in trisomy 1q. The t(1;2) was associated with a t(9;22) in 1 ANLL case and in the ALL case; +8 was found in 1 ANLL case and del( 7q) in the ALL case. The karyotypes were complex in 2 cases. The t(1;2) is likely to be a secondary anomaly. |
