Q Is the reflex test useful for rare BCR-ABL1 transcript forms, such as the e19/a2 p230 type? A No. 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 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) is designated as a major molecular response (MMR) threshold.

In Ph+ ALL, the majority of cases harbor an e1-a2 BCR-ABL1 mRNA transcript, producing a p190 protein. 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. In CML, the breakpoint in BCR is almost always in the major breakpoint cluster region (M-BCR), leading to the production of BCR-ABL1 protein of a larger size (the protein is called p210). Breaks in the minor breakpoint cluster region (m-BCR) leads to a shorter fusion protein (called p190), which is most frequently associated with Ph chromosome-positive ALL. 2016-05-27 They generated a conditional transgenic model of BCR-ABL-induced leukemia. The most common form of the product of the fusion gene, p210 BCR-ABL1, is found in more than 90% of patients with chronic myelogenous leukemia and in up to 15% of adult patients with de novo acute lymphoblastic leukemia. The presence or absence of BCR/ABL1 mRNA fusion form e13/e14-a2 producing the p210 fusion protein is identified.
