Translocation t(15;17) detected by FISH

The result of the t(15;17)(p;22;q22) translocation is the formation of the hybrid gene pml/rara and is a an indication of acute promyelocytic leukemia (APL).

This test is useful for patients with hemopoietic disorders for the diagnosis and/or confirmation of chronic and acute leukemia, for evaluation of remission or relapse or even after bone marrow transplantation for evaluation of recurrence of the disorder. The translocation is detected through FISH, using specific custom-labeled DNA probes, from at least 100 bone marrow cell nuclei.

This test may also be applied in combination with:
