External quality assessment (EQA) is an essential tool for quality assurance of analytical testing processes of p210 BCR‐ABL1 transcripts by RT‐qPCR. As an EQA provider, the National Center for Clinical Laboratories organized an EQA scheme of p210 BCR‐ABL1 testing in China for the first time to identify existing problems and ensure the reliability of p210 BCR‐ABL1 testing. This reflex test does screen for the common (p210, p190) and rare BCR-ABL1 variants, but is intended to provide quantitative results for only the p210 or p190 BCR-ABL1 transcript types at the time of diagnosis, in order to know which fusion should be followed in subsequent minimal residual disease assessment. Expression of either P190 BCR/ABL1 or P210 BCR/ABL1 resulted in expansion of erythroid cells and stimulated erythropoietin-independent burst-forming unit-erythroid colony formation.
Transcripts resulting from the two major breakpoints, BCR-ABL1 e13a2 (b2a2) and e14a2 (b3a2), and an endogenous control gene ABL1 are amplified and results are expressed as a ratio percent (BCR-ABL1/ABL x 100) according to the International Scale (IS). BCR-ABL1 major (p210) fusion form is present in almost all cases of CML and in a subset of ALL cases (e13a2 or e14a2 transcripts) Useful in cases of Philadelphia chromosome positive (Ph+) ALL to quantify the BCR-ABL1 p190 fusion form Related Tests Useful for patients with an established BCR-ABL1 P210 [RT-qPCR] 9 KML BCR-ABL1 [FISH]4 BCR-ABL1 [RT-PCR]5 BCR-ABL1 P210 [RT-qPCR] 9 MDS -5/del(5q) [FISH] 4 7/del(7q) [FISH] 17/del(17p) [FISH] MPN JAK2: V617F 5 Panel: CALR, JAK2 (V617 & exon12) & MPL5 Eosinofili FIP1L1-PDGFRA [RT-PCR]5 Test Code BCR/ABL p210 BCR/ABL p210, Quantitative PCR Important Note. Per UW Hematopathology, The Xpert BCR-ABL Ultra test is intended to measure BCR-ABL1 to ABL1 percent ratios on the International Scale (IS), in t(9;22) positive CML patients during monitoring of treatment with Tyrosine Kinase Inhibitors (TKIs). BCR-ABL1 transcripts may become molecularly undetectable, depending on the sensitivity of detection of the quantitative PCR assay. P210.
CONCLUSION.
The presence or absence of BCR/ABL1 mRNA fusion form e13/e14-a2 producing the p210 fusion protein is identified. If positive, the quantitative level is reported as the normalized ratio of BCR/ABL1 (p210) to endogenous ABL1 mRNA with conversion to a percentage referenced to the international scale (IS), on which 0.1% BCR/ABL1:ABL1 (also represented on a log scale as Molecular Response 3, or MR3

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 …

The Xpert BCR-ABL Ultra test is an in vitro diagnostic test for the quantitation of BCR-ABL1 and ABL1 mRNA transcripts in peripheral blood specimens of diagnosed t(9;22) positive Chronic Myeloid Leukemia (CML) patients expressing BCR-ABLl fusion transcripts type e13a2 and/or e14a2. The product of the Philadelphia chromosome (Ph) translocation, the BCR/ABL oncogene, exists in three principal forms (P190, P210, and P230 BCR/ABL) that are found in distinct forms of Ph-positive leukemia, suggesting the three proteins have different leukemogenic activity. We have directly compared …

REALQUALITY RQ-BCR-ABL p210 One-Step . Description. REALQUALITY RQ-BCR-ABL p210 One-Step is a CE-IVD kit for the identification and quantification of the t(9;22) (q34;q11) translocation, in the variant p210 (M-bcr b3a2 and b2a2 transcripts) , which involves the ABL proto-oncogene on chromosome 9 and part of the BCR gene on chromosome 22, by one-step Real-time RT-PCR of the BCR-ABL fusion gene.
Only BCR/ABL1:ABL1 changes of 0.5 log or greater should be considered significant. The reportable range of quantification for p210 is 50%IS (MR0.3) to 0.002%IS (MR4.7) and for p190 is 25 to 0.0025% BCR/ABL1:ABL1. Interpretation. An interpretive report will be provided. When BCR/ABL1 mRNA is present, quantitative results are reported on the international scale (IS), established from data originally reported in the IRIS (International Randomized Study of Interferon versus STI571) trial involving newly diagnosed chronic myeloid leukemia patients.
