Clinics and Pathology

Disease Chronic myelogenous leukaemia with t(9;22)(q34;q11) and blast crisis of CML (BC-CML) (4 cases altogether), other myeloproliferative syndromes, Acute myeloid leukaemia (AML) in 4 cases (one M1, 2 therapy related AML,one of which after breast cancer).
Epidemiology At least 9 cases to date, aged 62 years (medain, range: 49-78); sex ration was 5M/3F.
Prognosis No data


Cytogenetics Morphological Sole anomaly in 3 cases, with t(9;22)(q34;q11) in 4 cases (one of which was a complex translocation), with del(5q) (1 case), and with del(7q), and +21 in 1 case.

Genes involved and Proteins

Note The partner of EVI1 is yet unknown.
Gene NameMECOM (Ecotropic Viral Integration Site 1 (EVI1) and Myelodysplastic Syndrome 1 (MDS1-EVI1)
Location 3q26.2
Protein Transcrition factor; EVI1 targets include:GATA2, ZBTB16 /PLZF, ZFPM2/FOG2, JNK and the PI3K/AKT pathway. Role in cell cycle progression, likely to be cell-type dependant; antiapoptotic factor; involved in neuronal development organogenesis; role in hematopoietic differsntiation

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
