Description: Dan Jones, MD, PhD, discusses the BCR-ABL1 kinase domain and imatinib resistance in chronic myelogenous leukemia, and the clinical value of the international scale and trending reports for managing patients with CML. Learning objectives - at the conclusion of …

Test Description. RT-PCR and sequencing of the BCR-ABL1 fusion transcript for qualitative detection of mutations associated with resistance to Gleevec (imatinib) and other tyrosine kinase inhibitors. Analysis includes detection of all mutations recommended by guidelines, including the common T315I, Y253H, E255K/V, F359V/C/I, F317L/V/I/C, T315A, and

BCR-ABL QT Calibrated using First WHO International Genetic Reference Panel for quantitation of BCR-ABL1 translocation by RQ-PCR Interestingly, we found that >40% of BCR-ABL1 assays showed signs of inadequate optimization such as poor linearity and suboptimal PCR efficiency. Nonetheless, when optimized sample inputs were used, >60% demonstrated satisfactory IS accuracy, precision and/or MR(4.5) sensitivity, and 58% obtained IS conversion factors from the secondary reference concordant with their current values. WHO International Genetic Reference Panel for the quantitation of BCR-ABL1 translocation. Please note the WHO 1 st International Genetic Reference Panel for the quantitation of BCR-ABL1 translocation (09/138) is typically restricted to laboratories calibrating secondary standards or kits/assays to be used by others.. Other laboratories may consider participating in a sample exchange program Plasma cTK activity was closely correlated with cellular BCR-ABL1 kinase activation as indicated by phosphorylation of the downstream signaling proteins CRKL (P < 0.001) and STAT-5 (P= 0.003). However, cTK activity was not associated with BCR-ABL1 transcript level and was independent of BCR-ABL1 … This FISH panel has been designed to detect ABL1, ABL2 and PDGFRB rearrangements associated with the BCR-ABL1-like B-ALL (or Ph-like B-ALL) with ABL class fusions. Diagnosis of BCR-ABL1-like B-ALL patients with ABL1, ALB2 and PDGFRB rearrangements, will enable incorporation of TKI much earlier in the course of treatment as well as selection of patients eligible for future therapy trials Identification of BCR-ABL1 fusion gene amplification status is critically important in the effective management of chronic myelogenous leukemia (CML) patients.

FISH, CML/ALL, bcr/abl, Translocation 9,22 - This test is performed to detect the molecular rearrangement of the BCR and ABL1 genes involved in translocation t(9;22) associated with chronic myelogenous leukemia (CML), acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML) using FISH (fluorescence in situ hybridization).

BCR ABL1 Negative and Ph Negative. CML not diagnosed; evaluate for other MPNs.

The ABL kinase domain mutation test uses reverse transcription–polymerase chain reaction (RT-PRC) to amplify the BCR1-ABL fusion transcript before sequence analysis of the ABL kinase domain. If the patient’s tumor burden is low, RT-PCR may not generate enough of the BCR-ABL1 transcript for sequence analysis of the ABL kinase domain.

QIAGEN GmbH, QIAGEN Strasse 1, 40724 Hilden, GERMANY R3. 1072509EN Screening was conducted by first amplifying the fusion BCR-ABL1 transcript, to ensure that normal ABL1 was not amplified, then sequencing the ABL1 kinase domain coding region. We discovered 3 not previously described splice mutants, present in one patient each.

Figure 3. BCR-ABL1 transcript ratio near the laboratory median was pooled with nine follow-up samples that had undetectable BCR-ABL1 transcript levels (LOD >4 log). This pooled sample was tested and compared to ARQ IS calibrator panels (Asuragen, Austin, TX) to show an undiluted con-centration of 10% on the IS. The diluent RNA was obtained RT-PCR and sequencing of the BCR-ABL1 fusion transcript for qualitative detection of mutations associated with resistance to Gleevec (imatinib) and other tyrosine kinase inhibitors. Analysis includes detection of all mutations recommended by guidelines, including the common T315I, Y253H, E255K/V, F359V/C/I, F317L/V/I/C, T315A, and V299L.

A BCR-ABL genetic test helps diagnose CML, a type of leukemia. BCR-ABL is a genetic mutation formed by a combination of the BCR and ABL genes. Certain cancer medicines are especially effective in treating patients with the BCR-ABL mutation.
