| Clinics and Pathology |
| Disease | Acute myeloid leukaemia (AML), myelodysplastic syndrome (MDS) |
| Epidemiology | Only 3 cases to date, a 24-year-old female patient with a M2-AML, a patient with a treatment related AML (t-AML), and a 48-year-old patient with MDS ((Koo et al., 1998; Olney et al., 2002; Park et al., 2009). Although it is a rare chromosomal abnormality, it may be an aberration related to myeloid neoplasms including AML and MDS. |
| Prognosis | No detailed data available. However, one of them (Park et al., 2009) received bone marrow transplantation; complete donor chimerism was maintained for thirteen months until last follow up. |
| Cytogenetics |
| Cytogenetics Morphological | It shows balanced chromosomal translocation between 1q21 and 12q24. |
| Additional anomalies | The patient with a M2-AML also had an i(17q). The patient with a MDS had +8, +der(12)t(1;12) additionally. |
| Genes involved and Proteins |
| Note | The genes involved in this anomaly are unknown. |
| To be noted |
| 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. |
