Chronic myeloid leukemia is caused by a rearrangement (translocation ) of genetic material between chromosome 9 and chromosome 22. This translocation, written as t(9;22), fuses part of the ABL1 gene from chromosome 9 with part of the BCR gene from chromosome 22, creating an abnormal fusion gene called BCR-ABL1.

Definition. Chronic myeloid leukemia (CML), BCR-ABL1-positive, is a myeloproliferative neoplasm (MPN) in which granulocytes are the major proliferative component. It arises in a hematopoietic stem cell and is characterized by the chromosomal translocation t(9;22)(q34.
An abnormal chromosome called the Philadelphia chromosome is associated with chronic myelogenous leukemia. Your cells each contain 23 pairs of chromosomes that are made of DNA and hold the instructions for every cell in your body.
C95. 9 - Leukemia, unspecified. ICD-10-CM.
Also called chronic granulocytic leukemia, chronic myelogenous leukemia, and chronic myeloid leukemia.
BCR-ABL is a mutation that is formed by the combination of two genes, known as BCR and ABL. It's sometimes called a fusion gene. The BCR gene is normally on chromosome number 22. The ABL gene is normally on chromosome number 9. The BCR-ABL mutation happens when pieces of BCR and ABL genes break off and switch places.
Philadelphia chromosome. A piece of chromosome 9 and a piece of chromosome 22 break off and trade places. The BCR-ABL gene is formed on chromosome 22 where the piece of chromosome 9 attaches. The changed chromosome 22 is called the Philadelphia chromosome.
Leukemias that are caused by a mutation called Philadelphia chromosome are CML and Philadelphia chromosome-positive ALL. The mutation is a translocation, identified as, t(9;22)(q34;q11). This abnormal chromosome contains a fusion gene, consisting of the ABL gene and the BCR gene, producing the BCR-ABL oncogene.
A new genetic defect that predisposes people to acute myeloid leukemia and myelodysplasia has been discovered. The mutations were found in the GATA2 gene. Among its several regulatory roles, the gene acts as a master control during the transition of primitive blood-forming cells into white blood cells.
To help doctors plan treatment and predict prognosis, which is the chance of recovery, CML is divided into 3 different phases: chronic, accelerated, or blast. Chronic phase.
