A positive result from the BCR blood test indicates that the BCR-ABL1 gene sequence is present in their blood. 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.

It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. 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). It is also occasionally found in acute lymphoblastic leukaemia (ALL) mostly in adults and rarely in de novo acute myeloid leukaemia (AML). The presence of the gene sequence known as BCR-ABL1 confirms the diagnosis of CML and a form of acute lymphoblastic lymphoma (ALL), specifically a type of B-lymphoblastic leukemia/lymphoma. In very rare cases, the abnormal chromosome is linked to cases of acute myeloid leukemia and T-lymphoblastic leukemia/lymphoma.

Interpretation: A positive result (BCR-ABL1 fusion) is reported when the percent of cells with an abnormality exceeds the normal reference range for the probes. The detection of an abnormal clone indicates a diagnosis of CML, ALL or AML with the 9;22 translocation. BCR-ABL1 refers to a gene sequence found in an abnormal chromosome 22 of some people with certain forms of leukemia. Unlike most cancers, the cause of chronic myelogenous leukemia (CML) and some other leukemias can be traced to a single, specific genetic abnormality in one chromosome.

The test may also be used to: See if cancer treatment is effective. A positive result from the BCR blood test indicates that the BCR-ABL1 gene sequence is present in their blood.

As. 15 Aug 2011 BCR-ABL1–positive Abl1−/− leukemia cells were refractory to imatinib as ABL1 and BCR-ABL1 can exert opposite effects on a variety of cellular functions ( 2).

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.

It is also occasionally found in acute lymphoblastic leukaemia (ALL) mostly in adults and rarely in de novo acute myeloid leukaemia (AML). 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.
