In over 95% of CML patients, the typical BCR-ABL1 transcript subtypes are e13a2 (b2a2), e14a2 (b3a2) or expression of both simultaneously. Other less frequent transcript subtypes, such as e1a2, e2a2, e6a2, e19a2, e1a3, e13a3 and e14a3, have been sporadically reported. 1 Different subtypes of BCR-ABL1 transcripts encode fusion proteins with different sizes that may lead to different disease

BCR/ABL p210, Quant by RT PCR Description 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.

BCR-ABL1/ABL1 quantitative ratio is provided (normalized copy number) Results also reported in terms of BCR-ABL1 international scale (IS) Weakly positive. BCR-ABL1 fusion transcripts detected below the limit of quantitation. BCR-ABL1 to ABL1 ratio cannot be calculated. IS result <0.0069%. Not detected Consequently, the hybrid BCR-ABL1 fusion protein is referred to as p210 or p185. Three clinically important variants encoded by the fusion gene are the p190, p210, and p230 isoforms.

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. Expression of P190 and P210 BCR/ABL1 in normal human CD34(+) cells induces similar gene expression profiles and results in a STAT5-dependent expansion of the erythroid lineage. Experimental Hematology , 37 (3), 367-375.

The distributions by type of fusion transcript to BCR-ABL were p190 78.8%; p210 13.4% and their co-expression by both isoforms 8%. CONCLUSION. The 20% frequency for BCR-ABL1 in adults with ALL is concordant with others reports published, with values from 17% to 37% with predominancy of p190 (83%).

BCR-ABL — гибридный белок, продукт гибридного гена BCR-ABL1, формах : p190, p210 и p230, в зависимости от места прерывания BCR-фрагмента. This quantitative test is appropriate for diagnosis and therapeutic monitoring for CML or ALL. The BCR-ABL1 major (p210) fusion forms are present in almost all  Fukunaga et al. reported a case of MDS that presented an abrupt evolution to AML-MRC and the acquisition of the Ph chromosome (p210 BCR-ABL1).

BCR-ABL1 transcripts may become molecularly undetectable, depending on the sensitivity of detection of the quantitative PCR assay. P210. BCR-ABL1/ABL1 IS values ≤0.1% correspond to a 3-log or greater reduction from the baseline, indicating a major molecular response (MMR) in CML patients and thus excellent progression-free survival. 5

Test Description Real-time RT-PCR for quantitative detection of t (9;22) BCR-ABL1 fusion transcripts that result in major p210 (E13, E14) or minor p190 (E1) fusion proteins with option to add p230 detection (micro or atypical variant). p230 testing may be ordered as a stand-alone test.

The transcripts b2a2 or b3a2 code for a p210 protein. Another fusion gene leads to the expression of an e1a2 transcript, which codes for a p190 protein. Another, less common fusion … CONCLUSIONS: Various problems were found for p210 BCR-ABL1 detection in the EQA. By solving the existing problems, the performance of p210 BCR-ABL1 detection can be improved, ensuring robust laboratory diagnostic capacities in China. One hundred and forty-three patients with p210 BCR-ABL-positive leukemia were studied for coexpression of p190 BCR-ABL mRNA. p190 mRNA was detected in 14 of 16 (88%) patients with chronic-phase chronic myeloid leukemia (CML) at diagnosis, in 10 of 10 (100%) CML patients in blast crisis, in 75 of 107 … CML is mainly characterized by t (9; 22) (q34; q11) chromosomal translocation , giving rise to BCR-ABL1 p210 fusion protein with constitutive activation of tyrosine kinase activity. In most CML patients (~95%), the BCR-ABL1 rearrangement arises from two major breakpoints, involving exons 13 or 14 of BCR and exon 2 of ABL1 (e13a2 and e14a2) . The distributions by type of fusion transcript to BCR-ABL were p190 78.8%; p210 13.4% and their co-expression by both isoforms 8%.

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 BCR/ABL p210, Quant by RT PCR Description 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.

Objective. The P190 and P210 BCR/ABL1 fusion genes are mainly associated with different types of hematologic malignancies, but it is presently unclear 

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. Plasmid Bcr/Abl P210-pLEF from Dr. Nora Heisterkamp's lab contains the insert BCR/ABL P210 and is published in J Biol Chem.

This value is also designated on a log scale (Molecular Response, MR) as MR3. For further discussion of the international scale, see Clinical References. This quantitative test is appropriate for diagnosis and therapeutic monitoring for CML or ALL. The BCR-ABL1 major (p210) fusion forms are present in almost all cases of CML and in a small subset of cases of ALL.
