Also known as: t(6;9) FISH

Test category:

Oncology - Leukaemia

Use of test


Fusion of the DEK and NUP genes defines a specific AML subtype. This gene fusion is the result of a chromosomal translocation: t(6;9)(p22;q34). Identification of this fusion has prognostic implications.


Fusion of DEK and NUP is associated with an unfavourable prognosis in adults with AML

Ethical considerations:

This is an assay for non-heritable mutations. It does not raise issues of ethics or consent that are different from most other investigations ordered in the routine care of a patient.


Fluorescent in situ hybridisation (FISH) analysis, using probes designed to detect DEK-NUP gene fusion. The breakpoints involved in these fusions can be variable, and in some cases certain variants will not be detected by the probe.

Requesting the test


This test is usually requested by a haematologist or oncologist.

Sample required:

0.5 mL bone marrow in transport media (or 10 mL blood in lithium heparin if blasts >10%).

To help ensure the quality of the test, a genetic test should be done with a dedicated sample whenever possible i.e. a sample collected specifically for that test rather than a sample that is used for multiple tests.

We recommend that the patient or another adult check the labelling of request forms and sample tubes.

Turnaround time:

5 business days.
