BCR-ABL1 is in the center of chronic myeloid leukemia (CML) pathology, diagnosis and treatment, as confirmed by the success of tyrosine kinase inhibitor (TKI) therapy. However, additional mechanisms and events, many of which function independently of BCR-ABL1, play important roles, particularly in t … The BCR-ABL1 dPCR assay demonstrated detection capability at levels below MR 4.5, down to MR 5.0 to MR 5.5 in contrived samples from patients with CML. This increased sensitivity relative to RQ-PCR may aid future comparisons of deep MR rates across different CML therapies. dPCR assay performance is also more robust against primer/probe design changes than RQ-PCR, thus requiring less assay Hs03043652_ft: BCR-ABL1 b3a3/b3a2: BCR-ABL1: BCR, ABL1: 271 BCR-ABL1 testing is ordered to detect the Philadelphia (Ph) chromosome and BCR-ABL1 gene sequence. Several types of tests may be ordered to detect BCR-ABL1. These include chromosome analysis, BCR-ABL1 molecular genetic test, and/or fluorescence in situ hybridization (FISH). Cepheid's Xpert BCR-ABL Ultra is a quantitative test for BCR-ABL major breakpoint (p210) transcripts that provides highly sensitive and on-demand molecular results.

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). In CML, most translocations fall in the major breakpoint cluster region of the BCR gene, and The BCR-ABL1 fusion acts as an oncogene and promotes genomic instability. The advent of effective chemotherapy for CML in the late 1990s immediately demonstrated the need for accurate measurement of the amount of the abnormal clone remaining in the patient.

Schematic representation of the ABL1 and BCR genes and the BCR- ABL1 kinase.

Methods: BCR-ABL1 expression was studied in 248 samples from 65 patients with CML by determining the difference between MRD quantified by RT-qPCR and DNA-qPCR. The results were analysed statistically and by simple indicative modelling. The BCR-ABL1 dPCR assay demonstrated detection capability at levels below MR 4.5, down to MR 5.0 to MR 5.5 in contrived samples from patients with CML. This increased sensitivity relative to RQ-PCR may aid future comparisons of deep MR rates across different CML therapies.
