Panel Description
Diseases Targeted:
Hereditary Cancer and Cancer Syndromes
Overview:
The Full Comprehensive Cancer Panel examines 127 genes associated with hereditary cancer. This panel includes both well-established genes that increase a person’s risk for cancer, but also includes candidate genes that may have only been recently discovered or for which additional research is needed. This panel maximizes the chances of identifying a pathogenic cancer susceptibility variant, while providing a comprehensive review of candidate genes to give you information you can use now and potentially in the future.
Who is this test for?
Adults with a personal or family history suggestive of a hereditary cancer syndrome. Red flags for a hereditary cancer susceptibility could include onset of cancer prior to the age of 50 years, more than one primary cancer in a single person, and multiple affected people within a family. After consideration of a patient’s clinical and family history, this testing may be appropriate for some pediatric patients. (If there are specific genes that you do NOT want included, please indicate this on the test requisition form.) This test is designed to detect individuals with a germline pathogenic variant, and is not validated to detect mosaicism below the level of 20%. It should not be ordered on tumor tissue.
What are the potential benefits for my patient?
Patients identified with hereditary cancer susceptibility can benefit from increased surveillance and preventative steps to better manage their risk for cancer. Knowing the specific gene involved can guide medical management and avoid unnecessary follow up. Information obtained from candidate gene testing may be helpful in guiding clinical management in the future. Also, your patient’s family members can be tested to help define their risk. If a pathogenic variant is identified in your patient, close relatives (children, siblings, parents) could have as high as a 50% risk to also be at increased risk. In some cases, screening should begin in childhood.

Test Limitations:
Test results and variant interpretation are based on the proper identification of the submitted specimen and use of correct human reference sequences at the queried loci. In very rare instances, errors may result due to mix-up or co-mingling of specimens. Positive results do not imply that there are no other contributions, genetic or otherwise, to the patient's phenotype, and negative results do not rule out a genetic cause for the indication for testing. Official gene names change over time. Quick Biology uses the most up to date gene names based on HUGO Gene Nomenclature Committee (https://www.genenames.org) recommendations. If the gene name on report does not match that of ordered gene, please contact the laboratory and details can be provided. Result interpretation is based on the collected information and Alamut annotation available at the time of reporting. This assay is not designed or validated for the detection of mosaicism. DNA alterations in regulatory regions or deep intronic regions (greater than 20bp from an exon) will not be detected by this test. There are technical limitations on the ability of DNA sequencing to detect small insertions and deletions. Our laboratory uses a sensitive detection algorithm, however these types of alterations are not detected as reliably as single nucleotide variants. Rarely, due to systematic chemical, computational, or human error, DNA variants may be missed. Although next generation sequencing technologies and our bioinformatics analysis significantly reduce the confounding contribution of pseudogene sequences or other highly-homologous sequences, sometimes these may still interfere with the technical ability of the assay to identify pathogenic variant alleles in both sequencing and deletion/duplication analyses. Deletion/duplication analysis can identify alterations in genomic regions and is evaluated at a single exon resolution level in relevant genes associated with the patient's clinical presentation. For custom added genes and applicable genes that may be of interest, deletion/duplication analysis is evaluated at a resolution of two or more contiguous exons. When novel DNA duplications are identified, it is not possible to discern the genomic location or orientation of the duplicated segment, hence the effect of the duplication cannot be predicted. Where deletions are detected, it is not always possible to determine whether the predicted product will remain in-frame or not. Unless otherwise indicated, in regions that have been sequenced by Sanger, deletion/duplication analysis has not been performed. Patients with Bone Marrow Transplants: DNA extracted from cultured fibroblasts should be submitted instead of blood/saliva/buccal samples from individuals who have undergone allogeneic bone marrow transplant and from patients with hematologic malignancy.
