Clinics and Pathology

Disease Myeloproliferative syndrome (MPD) and acute myeloid leukaemia (AML)
Phenotype / cell stem origin One case was a M2-AML, another case was a MPD associated with an AML, the third case was an AML not otherwise specified.
Epidemiology Only three cases available; two male and one female patients aged 62, 63, and 71 yrs.

Cytogenetics

Cytogenetics Morphological The 3 cases were found using multi-FISH techniques; this translocation may therefore be partially cryptic, especially so as it is found in complex karyotypes.
Additional anomalies The three cases present with very similar cytogenetic profiles: major karyotypic anomalies were present in 3 out of 3 cases; -5/del(5q) was found in the three cases, and +8 and -14 were found in two cases each.

Genes involved and Proteins

Note Genes involved are unknown.

To be noted

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