The ABL gene is normally on chromosome number 9. The BCR-ABL mutation happens when pieces of BCR and ABL genes break off and switch places. Background: Philadelphia (Ph) chromosome results from the reciprocal translocation t(9;22)(q34.1;q11.2) and is diagnostic for chronic myeloid leukemia (CML). However, this translocation is also found in acute lymphoid leukemia (ALL), as well as in rare cases of acute myeloid leukemias (AML). BCR-ABL1 tyrosine kinase inhibitor K0706 exhibits preclinical activity in Philadelphia chromosome-positive leukemia.

Author information: (1)Huntsman Cancer Institute, University of Utah, Salt Lake City, UT. BCR‐ABL1 kinase domain mutation testing in tyrosine kinase inhibitor (TKI)‐resistant Philadelphia chromosome‐positive (Ph+) acute lymphoblastic leukaemia (ALL) patients is routinely performed by Sanger sequencing (SS).

The chromosomal defect in the Philadelphia chromosome is a reciprocal translocation, in which parts of two chromosomes, 9 and 22, swap places.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 q11). “The BCR-ABL1 gene fusion occurred due to the translocation between chromosome 9 and 22 results in chronic myeloid leukemia, the truncated chromosome is called the Philadelphia chromosome.” Chromosomal abnormalities can cause many types of disorders which are inherited as well as somatic (non-inherited). BCR-ABL1 fusion gene is the driver mutation of Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL).

Monitoring BCR-ABL1 transcript levels in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) is a widely adopted method to assess response to therapy. However, a small minority of Ph+ ALL patients express variant BCR-ABL1 transcript types, usually due to splicing of alternative BCR or ABL1 exons.

The BCR-ABL1 QRT-PCR test quantitatively measures the RNA blood level of BCR-ABL1, a marker for the presence and amount of transcriptionally active Philadelphia chromosome positive leukemia cells. For this test, total RNA from whole leukocytes is reverse transcribed with random primers and the cDNA product is quantitated by fluorescent real-time QRT-PCR.
