BCR-ABL is a mutation that is formed by the combination of two genes, known as BCR and ABL. It's sometimes called a fusion gene. The BCR gene is normally on chromosome number 22. The ABL gene is normally on chromosome number 9.

Background/Aim: The Philadelphia chromosome is the most frequent cytogenetic abnormality in chronic myelogenous (CML). More than 95% of CML patients are

6 nov.

BCR-ABL1 testing is requested to detect the Philadelphia (Ph) chromosome or the BCR-ABL1 gene sequence. It is used to: Help diagnose chronic myelogenous leukaemia (CML), a type of acute lymphoblastic leukaemia (ALL) or very rarely another type of leukaemia called acute myeloid leukaemia The collaborative validation study has assigned BCR-ABL1 / BCR; BCR-ABL1 / ABL1; BCR-ABL1 /GUSB values for four different freeze-dried cellular materials, each containing different amounts of BCR-ABL1.

However, a small minority of Ph+ ALL patients express variant BCR-ABL1 transcript types, usually due to splicing of alternative BCR or ABL1 exons.

Although various breakpoints within the BCR and ABL1 genes have been described, more than 95% of CMLs contain a consistent mRNA transcript in which either the BCR exon 13 (e13) or BCR exon 14 (e14) is fused to the ABL1 exon 2 (a2), yielding fusion forms e13/a2 and e14/a2, respectively. Chronic myeloid leukemia (CML) is a clonal myeloproliferative neoplasia characterized by the BCR-ABL1 fusion gene, derived from the t (9;22) translocation causing the Philadelphia Chromosome (Ph BCR/ABL1–like acute lymphoblastic leukemia (ALL) accounts for 15% to 30% of B‐lineage ALL, with a peak of incidence occurring in adolescence.This subgroup of patients is characterized by a peculiar transcriptional profile that resembles that of true BCR/ABL1–positive cases, and have a heterogeneous genetic background and a poor outcome. Probes: ABL1 (9q34); ASS1 (9q34; BCR (22q11.2) Disease(s): CML, ALL, MPN Note: For suspected ALL, STAT processing is available by request.

BCR-ABL is a mutation that is formed by the combination of two genes, known as BCR and ABL. It's sometimes called a fusion gene. The BCR gene is normally on chromosome number 22. The ABL gene is normally on chromosome number 9. The prognostic impacts of BCR-ABL1 fusion gene mutations in Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL) remain unknown. Using data from a nationwide Japanese registry, we have evaluated the prognostic impact of BCR-ABL1 mutations prior to the first allogeneic hematopoietic cell transplantation (HCT). The BCR-ABL1 transcript type influences response and outcome in Philadelphia chromosome-positive chronic myeloid leukemia patients treated frontline with imatinib. The chromosomal defect in the Philadelphia chromosome is a reciprocal translocation, in which parts of two chromosomes, 9 and 22, swap places.

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.
