A positive common p210 or p190 result will specifically trigger either quantitative p210 or p190 testing to provide a normalized Reference Values. 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 2020-09-20 · This assay can detect three different types of BCR-ABL1 fusion transcripts associated with CML, ALL, and AML:e13a2 (previously b2a2) and e14a2 (previously b3a2) (major breakpoint, p210), as well as e1a2 (minor breakpoint, p190). 2019-10-08 · In Ph+BCR-ABL1 P210+ acute lymphoblastic leukemia the e13a2 (B2A2) transcript is prevalent.

Cautions This test detects only the e13/a2 and e14/a2 fusion forms, which code for the p210 protein. Using the IS, a result of less than 0.1% BCR/ABL1 (p210): ABL1 is equivalent to a major molecular remission. This value is also designated on a log scale (Molecular Response, MR) as MR3. For further discussion of the international scale, see Clinical References.

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.

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 distributions by type of fusion transcript to BCR-ABL were p190 78.8%; p210 13.4% and their co-expression by both isoforms 8%.
