Breakpoint cluster region rearrangement in CML |
| Test | Breakpoint cluster region rearrangement in CML |
| Indication | This test characterize and monitor chronic myelogenous leukemia (CML) |
| Physiology | CML is characterised by reciprocal translocation between chromosomes 9 and 22 producing the philadelphia chromosome. The translocation involves a gene rearrangement of the breakpoint cluster region gene located on chromosome 22 with c-abl oncogene on chromosome 9. |
| Normal Range | Philadelphia chromosome has been found in 20% to 25% of patients with acute lymphoblastic leukemia and 2% of patients with acute myelogenous leukemia (AML) |
| Interpretation | Chromosome analysis, Polymerase chain reaction |
| Sample | No rearrangement observed |
| Test Method | Nucleic acid technology |
| Related Tests | Blood, bone marrow |
