SINGLE GENE ANALYSIS

Description

This test is for a single gene selected from the BROCA, ColoSeq™, and Megalencephaly panels, which must be clearly indicated in the space provided on the requisition. Additional single gene testing can be ordered via UW OncoPlex Single Gene [OPG].

For the complete list of genes, see the following pages:

This test uses next-generation sequencing to detect most mutations in the gene tested. Mutations in these genes are associated with hereditary cancer risk and megalencephaly syndromes. The assay completely sequences all exons, non-repetitive introns, and flanking regions of these genes AND detects large deletions and duplications.

Interpretation

Method

Next-generation sequencing.

Sequences are aligned to the human genome reference (hg19). Test performed by targeted capture for listed genes followed by next-generation sequencing with Illumina technology. This test was developed and its performance characteristics determined by the University of Washington Department of Laboratory Medicine. It has not been cleared or approved by the US Food and Drug Administration. This laboratory is certified under the Clinical Laboratory Improvement Amendments (CLIA) as qualified to perform high complexity clinical laboratory testing. This test is used for clinical purposes. It should not be regarded as investigational or for research.
