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.

However, cTK activity was independent of BCR-ABL1 transcript level and BCR-ABL1 mutation type. This test screens for the BCR-ABL1 p210 fusion form (major breakpoint) and when necessary the BCR-ABL1 p190 fusion form (minor breakpoint). The results of the BCR-ABL1 p210 assay are first normalized against the reference gene ABL1 and subsequently results are converted to an International Scale (%IS).

Consider other causes of TKI resistance . T315I . V299L, T315A, or F317L/V/I/C Y253H, E255K/V The BCR/ABL1 gene rearrangement test is not included in JAK2 V617F Cascading Reflex because it is an RNA-based test rather than a DNA-based test. RNA-based technology is better for detecting fusion transcripts such as BCR/ABL1. Additionally, BCR/ABL1 fusion transcript results must be normalized and reported according to the Once a BCR-ABL1 fusion is detected, subsequent samples from the patient will be tested for the indicated isoform only.

The kit provides reagents optimized for reliable and sensitive detection and quantification of BCR-ABL Mbcr b2a2 or b3a2 transcripts, relative to ABL control gene expression, in total RNA. 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. 2013-07-26 · July 26, 2013 – Revised: December 22, 2014.

Effective for services performed on or after 11/3/2014, coverage requirements for this test is addressed in CGS's Local Coverage Determination (LCD) for Molecular Diagnostic Tests (L35394).

In addition, scientists from Quest Diagnostics and M.D. Anderson Cancer Center identified three novel (previously undescribed) mutations along the BCR-ABL tyrosine kinase that may constitute a new class of mutations that "confer significant drug resistance" to imatinib therapy by expressing a truncated BCR-ABL1. 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. BCR-ABL1, Major pin pin.

BCR-ABL1 transcript levels are expressed as a percent ratio of BCR-ABL1 to the normalizing ABL1 transcript levels. For the p210 transcript associated with CML, quantitation is further adjusted to the international scale (IS) to allow comparison with other IS-compliant BCR-ABL1 assays.

A BCR-ABL1/ABL1 % IS value of 100% represents the level at diagnosis in most patients, which is similar to the universal baseline used in the landmark International Randomized Study of Interferon and STI571 (IRIS) trial. 5 For P190, results will be expressed as the percent ratio: (BCR-ABL1/ABL1 ratio) x 100.
