The materials consist of 4 different dilutions of K562 cells (Philadelphia chromosome positive) in HL60 cells (Philadelphia chromosome negative). 2005-10-01 While BCR-ABL1 translocations can occur in T-ALL, they are very rare and the NUP214-ABL1 fusion is more common in T-ALL. 16–18 Our data however indicate that the increasing use of CD19-directed therapies may guide leukemic cells to more inventive escape mechanisms, not only by relapsing as CD19-negative, BCR-ABL1 positive myeloid leukemia, but possibly also as CD19-negative, BCR-ABL1 One thing that does stand out to me is that there are no actual copies of BCR-Abl shown as detected on the report. There are 10693 copies of the Abelson control gene, and unless my maths is failing me terribly, 0 over 10693 is 0, not 0.01 (or 0.006).

It arises in a hematopoietic stem cell and is characterized by the chromosomal translocation t(9;22)(q34.1;q11.2), which results in the formation of the Philadelphia ( Ph ) chromosome , containing the BCR-ABL1 fusion gene . A BCR-ABL test is most often used to diagnose or rule out chronic myeloid leukemia (CML) or a specific form of acute lymphoblastic leukemia (ALL) called Ph-positive ALL. Ph-positive means a Philadelphia chromosome was found. The test is not used to diagnose other types of leukemia.

The test is not used to diagnose other types of leukemia. The test may also be used to: See if cancer treatment is effective. The BCR/ABL1 fusion gene, usually carried by the Philadelphia chromosome (Ph) resulting from t(9;22)(q34;q11) or variants, is pathognomonic for chronic myeloid leukaemia (CML).

The numeric BCR-ABL1 level is reported as % BCR-ABL1/ABL1 and the detection sensitivity is 4.5 log below the standard baseline (<0.0032%).

In over 95% of CML patients, the typical BCR-ABL1 transcript subtypes are e13a2 (b2a2), e14a2 (b3a2) or expression of both simultaneously. Question 7.

This may or may not be accompanied by detection of the Philadelphia chromosome. In up to 95% of people who are diagnosed with CML, the Philadelphia chromosome is present and 100% will have the gene sequence. Philadelphia Chromosome Positive, Bcr-abl1 Positive Chronic Myelogenous Leukemia is also known as Ph' Positive Chronic Granulocytic Leukemia, Ph' Positive Chronic Myelogenous Leukemia, Ph1 Chromosome Positive Chronic Myelocytic Leukemia, Ph1 Chromosome Positive Chronic Myelogenous Leukemia, Ph1 Chromosome Positive Chronic Myeloid Leukemia. BCR-ABL1 quantitative testing is recommended for patients with either chronic myelogenous leukemia (CML), a hematopoietic stem cell disease, or acute lymphoblastic leukemia (ALL), an aggressive type of leukemia of either B- or T-lineage immature lymphoid cells. 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. Serial dilutions of a validated positive control RNA with known t(9;22) BCR-ABL1 are used as reference for quantification of BCR-ABL1 relative to ABL1. The numeric BCR-ABL1 level is reported as % BCR-ABL1/ABL1 and the detection sensitivity is 4.5 log below the standard baseline (<0.0032%).
