Special Instructions

A hereditary cancer clinical questionnaire should be submitted with all specimens. Contact CMBP genetic services at 800-345-4363 to coordinate testing. To order Oragene Dx 500 saliva collection kits using PeopleSoft No. 87917, contact your local Labcorp branch supply department.

Limitations

Sequencing cannot detect variants in regions not covered by this analysis, including noncoding or deep intronic variants, and may not reliably detect changes in repetitive elements, such as microsatellite repeats. Sequencing may not detect mosaic variants, inversions, or other genomic rearrangements such as transposable element insertions. The method does not allow any conclusion as to whether two heterozygous variants are present on the same or on different chromosome copies. Copy number analyses may not detect certain genomic rearrangements, such as translocations (balanced or unbalanced), inversions, or some partial exon rearrangements. This assay cannot determine exact breakpoints of deletions or duplications. The presence of pseudogenes can interfere with the ability to detect variants in certain genes.
