| Clinics and Pathology |
| Disease | Chronic myelogenous leukemia (CML) in blast crisis; the t(X;21) may be therapy related. |
| Epidemiology | Only one case to date, a female patient aged 23 years (Jeandidier et al., 2006). |
| Cytogenetics |
| Additional anomalies | t(9;22)(q34;q11), +8, i(17q). |
| Genes involved and Proteins |
| Note | The partner of RUNX1 is unknown. |
| Gene Name | RUNX1 (runt-related transcription factor 1 (acute myeloid leukemia 1; aml1 oncogene)) |
| Location | 21q22.12 |
| 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. |
| 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. |
