More than 90% of patients diagnosed with Chronic Myeloid Leukemia bear a Philadelphia chromosome resulting from t(9;22)(q34.1;q11.2), which is a reciprocal translocation between chromosome 22 (''BCR'' locus) and chromosome 9 (''ABL1'' locus) (see '''[http://www.omim.org/entry/613065 OMIM]''') [1].  The Drug Imatinib mesylate, also known as Gleevec, was the one of the first molecularly developed drugs, and has a remarkably high success rate in treatment of patients with Chronic Myeloid  Leukemia by targeting the BCR/ABL1 fusion product [5].

Approximately 20% of patients (25 - 30% of adults and 2 - 10% of children) diagnosed with Acute Lymphoblastic Leukemia bear a Philadelphia chromosome resulting from t(9;22)(q34.1;q11.2), which is a reciprocal translocation between chromosome 22 (''BCR'' locus) and chromosome 9 (''ABL1'' locus) (see '''[http://www.omim.org/entry/613065 OMIM]''') [1].  Treatment of Acute Lymphoblastic Leukemia patients with Gleevec does not have the same success as in Chronic Myeloid Leukemia patients because the genomic instability of ALL cells contributes to point mutations arising in the BRC-ABL1 kinase domain, leading to Gleevec resistance [4].
