InJanet Rowley at the University of Chicago identified the mechanism by which the Philadelphia chromosome arises as a translocation. The need of quantitative methods is evident, but technical problems in standardization limits its application philsdelphie residual disease evaluation.

The symbol BCR is derived from breakpoint cluster region, a gene which encodes a protein that acts as a guanine nucleotide exchange factor for Rho GTPase proteins. The mutation became known as the Philadelphia chromosome. This is a philadelphis translocation, creating an elongated chromosome 9 termed a derivative chromosome, or der 9and a truncated chromosome 22 the Philadelphia chromosome, 22q.

The result is that a fusion gene is created by juxtaposing the ABL1 gene on chromosome 9 region q34 to a part of the BCR breakpoint cluster region gene on chromosome 22 region q Small molecule inhibitors, like arsenic trioxide and geldanamycin analogues, have also been identified in downregulating BCR-ABL kinase translation and promoting its degradation by protease.
