chronic myeloid leukemia
Evolution
Cytogenetics
Most patients with chronic myelogenous leukemia (CML) show a Philadelphia (Ph) chromosome with a characteristic translocation between chromosomes 9 and 22.
There are variant complex translocations involving other chromosomes in addition to the standard translocation:
t(4;12;7;9;22) (18474301)
Molecular biology
BCR-ABL fusion protein expression by t(9;22)
