| Identity |
| ICD-Topo | C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS |
| ICD-Morpho | 9861/3 AML with mutated NPM1; AML with mutated CEBPA; Acute myeloid leukaemia, NOS |
| Atlas_Id | 1307 |
| Clinics and Pathology |
| Disease | Acute myeloid leukaemia; blast crisis (of myeloid type) of chronic myelogenous leukaemia |
| Epidemiology | Four cases available: 4 male patients aged 44, 57, 67, and 72 (yrs). |
| Cytogenetics |
| Additional anomalies | No additional anomaly in one case, monosomy 5 and major karyotypic anomalies in one case, t(9;22)(q34;q11) in the two remaining cases. |
| Genes involved and Proteins |
| Note | RUNX1 was found involved in the translocation in the two cases where it was studied; the partner is unknown. |
| Gene Name | RUNX1 |
| Location | 21q22 |
| Protein | RUNX1, also called AML1 or CBFA2, is a transcription factor, critical regulator of hematopoietic-cell development, involved in many de novo and treatment related leukaemias. |
| 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. |
