What is a BCR-ABL1 genetic test? A BCR-ABL1 genetic test uses a sample of blood or bone marrow to look for an abnormal gene called BCR-ABL1. This abnormal gene is involved in certain types of blood cancer. It's found in: Most people who have chronic myeloid leukemia (CML), which is also called chronic granulocytic leukemia or chronic myeloid ...

The BCR-ABL test stands as a pivotal tool in the diagnosis and management of chronic myeloid leukemia. Its ability to pinpoint the presence of the BCR-ABL fusion gene offers insights into disease progression, guiding tailored treatment plans and fostering better patient outcomes.

2020年11月6日 · BCR-ABL1 testing detects the presence of the BCR-ABL1 gene sequence in an abnormal chromosome 22 to help diagnose chronic myelogenous leukemia and a form of acute lymphoblastic lymphoma.

BCR::ABL1 (BCR-ABL1) testing is recommended for patients with either chronic myeloid 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.

Other names: BCR-ABL1, BCR-ABL1 fusion, Philadelphia chromosome What is it used for? 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.

A chronic myeloproliferative neoplasm characterized by the expression of the BCR-ABL1 fusion gene. It presents with neutrophilic leukocytosis. It can appear at any age, but it mostly affects middle aged and older individuals.

BCR-ABL1 is a multidomain, constitutively active, chimeric tyrosine kinase that results from a reciprocal translocation between chromosomes 9 and 22—t (9;22) (q34;q11)—characteristic of Philadelphia chromosome (Ph1)-positive leukemia [1].

BCR-ABL1–transformed cells exhibit deregulated cell proliferation, growth-factor independence, and reduced apoptosis, which result from the activation of an intricate network of signaling pathways and override the tightly regulated homeostatic molecular circuits that govern the growth and differentiation of hematopoietic progenitors. However ...

The BCR-ABL1 fusion acts as an oncogene and promotes genomic instability. The advent of effective chemotherapy for CML in the late 1990s immediately demonstrated the need for accurate measurement of the amount of the abnormal clone remaining in the patient.

A protein made from pieces of two genes that get joined together. The BCR-ABL1 fusion protein is found in most people with chronic myelogenous leukemia, and in some people with acute lymphoblastic leukemia or acute myelogenous leukemia.
