Example: Translocation of Bcr-Abl Genes

< Previous SectionNext Section >

In chronic myelogenous leukemia, a translocation occurs between chromosomes 9 and 22. This rearrangement of genomic material creates a fusion gene call Bcr-Abl that produces a protein (tyrosine kinase) thought to promote the development of leukemia. The drug Gleevec blocks the activation of the Bcr-Abl protein.
