Exome: patient only: 81415, -Exome Duo: patient + (1) family member: 81415 + 81416, - Exome Trio: patient + (2) family members: 81415 + 81416 + 81416, - Exome Quad: patient + (3) family members: 81415 + 81416 + 81416 + 81416, 81416 - Exome Mitochondrial: Patient: 81460, - Exome Mitochondrial: Family Member: 81403 - Exome Re-Analysis: 81417

Includes

Exome sequencing examining thousands of genes, looking for disease-causing genetic changes.

Preferred Specimen

3 mL whole sterile blood collected in an EDTA (lavender-top) tube.

Minimum Volume

1 mL whole blood collected in an EDTA tube.
Pediatric: 1ml EDTA whole blood

Other Acceptable Specimens

extracted DNA minimum 3 μg (minimum concentration of 35 ng/ μl) from CLIA certified laboratory OR a laboratory meeting equivalent requirement as determined by the CAP and/or the CMS. When DNA concentration is measured using a fluorescence-based method such as Qubit, 3 µg of DNA is adequate. In contrast, spectrophotometric measurements often overestimate DNA concentration, so roughly twice that amount is recommended to ensure sufficient material.

Transport Temperature

Refrigerated: 2-8°C

Specimen Stability

Room temperature: 2 days
Refrigerated: 14 days
Frozen: Unacceptable
Genomic DNA (once sample has been extracted) can be stored at +2-8°C for one week or -20°C for 1 month)

Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)

Heparinized samples are not accepted. Heparin may act as an inhibitor of PCR.
We DO NOT accept DNA from Formalin-Fixed Paraffin-Embedded (FFPE) Tissue

Methodology
Next Generation Sequencing performed on the Illumina NextSeq 2000.

Setup Schedule

Variable, depending on insurance approval status
Turnaround Time: 75 days (once pre-authorization is approved)

Reference Range

NO Clinical Variants Detected

Clinical Significance

This WVU-XSeq assay is intended for detection of disease-causing genetic variants in individuals with a suspected germline genetic disorder. It may be performed for initial diagnosis, to inform clinical management and therapeutic decision-making, or to provide information relevant to family planning and counseling.

Performing Laboratory
West Virginia University Hospitals, Inc.
