Blood,Tissue, Buccal Swab, and Extracted DNA specimens

Are received Mon – Fri: 07:30 to 15:00.
If received after 15:00, will be processed on the next working day.

If Tissue specimens are sent from outside of Edmonton for testing in Molecular Genetics North, please call the laboratory at 780-407-1434 or fax shipping information to 780-407-1761 to inform the lab of expected arrival times and mode of transport.

Submitting to Molecular Genetics South
Transport specimens to Molecular Genetics Laboratory at Alberta Children’s Hospital Room B0-020.

Method:

Next Generation Sequencing

Method and Interpretation of Results:

Genomic DNA is analyzed using next generation sequencing technology (NGS). NGS detects nucleotide substitutions, small insertions and deletions, and copy number variants. If a variant is clinically relevant or of uncertain significance and does not meet our validated analytic requirements it is confirmed by an appropriate molecular method. Sanger sequencing is used to analyze regions which do not meet requirements for depth of sequence coverage.

EPCAM (exon copy number only).

PMS2 by MLPA: Detects deletions and duplications. Copy number analysis by MLPA is completed on exons 11-15 only if clinically indicated. i.e. IHC results.

Routine Turn Around Time:

Routine: up to 16 weeks, Stat: 4 weeks

Reference Interval:

Interpretation provided on report.

Testing Area:

Molecular Genetics

Performing Site:

University of Alberta Hospital or Alberta Children's Hospital
