Inv(16) Transcript Detection by PCR
Also known as : [Inv16],[RT-PCR]


DNA/RNA
Test performed by: LabPLUS - Dept. Diagnostic Genetics - Molecular Haematology


Specimen Collection

NOTE: RNA is highly unstable and specimens degrade rapidly. For optimum results samples should be sent in CPD tubes at room temperature and be received by this lab within 24 hours of collection. Although LabPlus operates 24 hours a day, 7 days a week, the Molecular Haematology section only operates 9-5, Mon-Fri (excluding public holidays). Samples arriving on a Friday afternoon or a Saturday or Sunday may not get processed until the following Monday. Such delays can significantly compromise the quality of the sample. 


CPD9 mL CPD Blood (Preferred)

Turnaround Time: Within 2 weeks, 4 days
Diagnostic Use and Interpretation

This PCR tests for the presence of the fusion transcript resulting from the pericentric inversion of chromosome 16, inv(16)(p13q22).

Information on Inv(16):

This PCR tests for the presence of the fusion transcript resulting from the pericentric inversion of chromosome 16, inv(16)(p13q22).  A variant resulting in the same fusion is t(16;16)(p13;q22). The inversion/translocation forms a fusion gene made up of parts of the CBFB gene (core binding factor beta subunit) located on 16q22 fused to the MYH11 gene (myosin heavy chain 11) located on 16p13.  Ten different CBFB-MYH11 fusion transcripts have been reported (types A to J).
