BCR-ABL1 Translocation Test Cost & Procedure

BCR-ABL translocation: what is it? BCR-ABL is a mutation that results from the fusion of the two genes BCR and ABL. The BCR gene is typically located on chromosome 22. The ABL gene is typically located on chromosome 9. The BCR-ABL mutation is caused when bits of the BCR and ABL genes separate and swap positions.

A genetic mutation (change) on a particular chromosome is what a BCR-ABL test searches for. Your cells' chromosomes are the components that house your genes. Your mother and father pass down genes, which are pieces of DNA. The average human cell contains 23 pairs of the 46 chromosomes that make up their genome.

Your mother contributes one set of each pair of chromosomes, and your father contributes the other set. Two genes, BCR and ABL, come together to create the mutation known as BCR-ABL. Normally, the BCR gene is located on chromosome 22. On chromosome 9, the ABL gene is typically located. In the BCR-ABL

The BCR-ABL mutation is caused when bits of the BCR and ABL genes separate and swap positions. The ABL gene is a portion of the chromosome 9 fragment that separates. Part of the ABL gene joins the BCR gene as it translocates to chromosome 22. The BCR-ABL fusion gene is the name of the combined gene. The Philadelphia chromosome is named after the city where researchers initially found the altered chromosome 22, which houses the BCR-ABL gene. It is not possible to inherit the BCR-ABL gene mutation from your parents. Because it is a somatic mutation, you are not born with it. It comes later in life.

Some forms of leukemia, a malignancy of the bone marrow and white blood cells, are associated with the BCR-ABL gene. Almost all individuals with the leukemia type known as chronic myeloid leukaemia have BCR-ABL (CML). Chronic myelogenous leukemia is another name for this condition. The same illness is described by both terms.

Acute lymphoblastic leukemia (ALL) individuals and, less frequently, those with acute myelogenous leukemia have the BCR-ABL gene as well (AML).

What does it accomplish?

Ph-positive denotes the presence of the Philadelphia chromosome.

found Some forms of leukemia are not diagnosed with the test.

The examination can also be used to

Identify the efficacy of cancer treatment.

Check to see if a patient has grown resistant to a specific course of treatment. It indicates that a previously successful treatment is no longer effective.
