The precision of this assay at low BCR/ABL1 levels is more variable, such that inter-run variation can be as high as + or - 0.5 log. Results. Bcr-Abl expression is higher in progenitor cells of patients in blast crisis than in those of chronic phase patients. Expression of the Bcr-Abl protein varied over >1 log in the CD34 + cells of the CML samples analyzed, but was significantly higher in patients in blast crisis than in those in chronic phase (P = 0.0079, Mann-Whitney U test; Fig. 1A). This assay detects the most common BCR-ABL fusions (the M-bcr transcripts, resulting in the P210 protein product).

BCR-ABL1-like B-lymphoblastic leukemia/lymphoma (BCR-ABL1-like ALL or Ph-like ALL) is a neoplastic proliferation of lymphoblasts that has a gene expression profile similar to that of B-ALL with t(9;22)(q34.1;q11.2) BCR-ABL1, but lacks that gene fusion. It is associated with poor prognosis and is see … breakpoint in ABL is variable over a region of 200 kb, often between the two alternative exons 1b and 1a, sometimes 5' of 1b, or 3' of 1a, but always 5' of exon 2; - breakpoint in BCR is either (as in ALL cases): 1- in the same region as in CML, called M-bcr (for major breakpoint cluster region), a cluster of 5.8 kb, between exons 12 and 16 Combination of Ig/TCR and BCR-ABL1 genomic approach for MRD monitoring in childhood ALL reveals patients with CML-like disease. Monitoring ALL using BCR-ABL1 genomic breakpoint is feasible and enables the most specific and sensitive MRD quantification. BCR-ABL1 Gene Rearrangement, Quantitative, PCR - The Philadelphia Chromosome (Ph) is a translocation between chromosome 9 and 22 t(9; 22) (q34; Q11) that is found in more than 90-95% of chronic myeloid leukemia (CML), and in 20-25% of adult and 2-10% of childhood acute lymphoblastic leukemia (ALL).

The BCR-ABL1 fusion acts as an oncogene and promotes genomic instability.
