Quantitation of BCR-ABL1 p210 transcripts in peripheral blood for diagnosis and monitoring. 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).

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 … Acute lymphoblastic leukemia (ALL), Acute myeloid leukemia (AML), B lymphoblastic leukemia (B-ALL), T lymphoblastic leukemia (T-ALL), BCR-ABL1, BCR ABL, BCR/ABL, Chronic myelogenous leukemia (CML), Philadelphia chromosome, Ph bone marrow/blood t(9;22), Tyrosine kinase inhibitor (TKI) therapy monitoring, PCR This gene encodes for a BCR-ABL1 fusion protein. Depending on the precise location of fusion, the molecular weight of this protein can range from 185 to 210 kDa. Consequently, the hybrid BCR-ABL1 fusion protein is referred to as p210 or p185. The presence or absence of BCR/ABL1 mRNA fusion form e13/e14-a2 producing the p210 fusion protein is identified.

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 … 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%). 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.

Dai HP (1), Xue YQ, Wu LL, Pan JL, Gong YL, Wu YF, Zhang J, Wu DP, Chen SN. 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. 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 … The BCR-ABL1 Gene Rearrangement, Quantitative PCR test can measure the 2 P210 transcripts (e13a2 and e14a2) as well as the P190 transcript (e1a2).

To monitor patients carrying BCR/ABL1 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 p210 BCR/ABL1 as a secondary change in a patient with acute myelomonocytic leukemia (M4Eo) with inv(16).
