Germline Panels

OVERVIEW

Our laboratory offers germline panel testing via a Hereditary Cancer Multi-Gene Panel and a Pediatric Cancer Predisposition Panel.  These multi-gene next-generation sequencing panel tests are available for patients known or suspected to be at risk of a cancer predisposition syndrome.  For eligibility, indications, and ordering information, see our Hereditary Cancer page.

TEST REQUIREMENTS

For eligible patients:

  • Completed requisition form
  • 5mL EDTA peripheral blood (see Specimen Guidelines, DNA molecular test type)

For all other patients, please initiate a referral to the Hereditary Cancer Program.

TURN-AROUND TIME

Approximately 42 days from receipt of specimen and completed and signed requisition form. 

RESULTS REPORTING

Germline variants are classified according to ACMG Guidelines (Richards (2015) PMID: 25741868) as one of:

  • Pathogenic
  • Likely Pathogenic
  • Variant of Uncertain Significance (VUS)
  • Likely Benign
  • Benign

Please see our Variant Classification Guidelines for additional details. Benign and Likely Benign variants are not routinely reported.  Only Pathogenic or Likely Pathogenic variants are reported for a subset of targeted genes (see below).

Reduced sensitivity targets:

Due to low mapping quality, this assay has reduced sensitivity and may not be able to call variants in the following targets: SLX4:NM_032444 (exon 13); FANCD2:NM_001018115 (exons 1-14, exon 17, exon 22)

* For patients presenting with solid tumours, variants not presumed by nature or already known to be (likely) pathogenic are not reported for these genes.

** For patient presenting with a hematologic malignancy, variants not presumed by nature or already known to be (likely) pathogenic are not reported for these genes.
