translocation
Fusion of 2 genes: BCR (or chromosome
22) and ABL1 (on chromosome 9),
resulting in BCR-ABL1 fusion gene

Investigations
CBC
Blood film
Blood film at 1000X magnification
shows a promyelocyte, an
eosinophil, and 3 basophils.
Blood film at 400X magnification
demonstrates leukocytosis with the presence
of precursor cells of the myeloid lineage. In
addition, basophilia, eosinophilia, and
thrombocytosis can be seen.
