Cancer Category/Type

Chronic Myeloid Leukemia (also referred as (Chronic Myelogenous Leukemia)

More than 90% of patients diagnosed with Chronic Myeloid Leukemia bear a Philadelphia chromosome t(9;22)(q34.1;q11.2), which is a reciprocal translocation between chromosome 22 (BCR locus) and chromosome 9 (ABL1 locus (1, also see OMIM). 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 (5)

Acute Lymphoblastic Leukemia

Approximately 20% of patients (25 - 30% of adult and 2 - 10% of children) diagnosed with Acute Lymphoblastic Leukemia bear a Philadelphia chromosome t(9;22)(q34.1;q11.2), which is a reciprocal translocation between chromosome 22 (BCR locus) and chromosome 9 (ABL1 locus) (1, also see OMIM).

Gene Overview

The ABL1 gene encodes for a non-receptor tyrosine kinase that is ubiquitously expressed and involved in a large number of cellular processes (see "NCBI Gene). A reciprocal translocation between chromosome 22 (BCR locus) and chromosome 9 (ABL1 locus) produces the Philadelphia chromosome t(9;22)(q34.1;q11.2), which is prevalent in chronic myeloid leukemia (1, 2).
