Test Code COMCP Hereditary Common Cancer Panel, Varies


Ordering Guidance


Customization of this panel and single gene analysis for any gene present on this panel are available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.

 

Targeted testing for familial variants (also called site-specific or known mutations testing) is available for the genes on this panel. For more information see FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.

 

Testing minors for adult-onset predisposition syndromes is discouraged by the American Academy of Pediatrics, the American College of Medical Genetics and Genomics, and the National Society of Genetic Counselors.

Useful For

Evaluating hereditary cancer for patients with a personal or family history suggestive of a hereditary cancer syndrome

 

Establishing a diagnosis of a hereditary cancer syndrome allowing for targeted cancer surveillance based on associated risks

 

Identifying genetic variants associated with increased risk for cancer, allowing for predictive testing, and appropriate screening of at-risk family members

 

Therapeutic eligibility with poly adenosine diphosphate-ribose polymerase (PARP) inhibitors based on certain gene alterations (eg, BRCA1, BRCA2) in selected tumor types

Genetics Test Information

This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 36 genes associated with hereditary cancer syndromes: APC (including promoters 1A and 1B), ATM, AXIN2, BARD1, BMPR1A, BRCA1, BRCA2, BRIP1, CDH1, CDK4, CDKN2A, CHEK2, DICER1, EPCAM (copy number variants only), GREM1 (upstream enhancer region duplication only), HOXB13, MEN1, MLH1, MSH2, MSH3, MSH6, MUTYH, NBN, NF1, NTHL1, PALB2, PMS2, POLD1, POLE, PTEN (including promoter), RAD51C, RAD51D, RET, SMAD4, STK11, TP53. For more information, see Method Description and Targeted Genes and Methodology Details for Hereditary Common Cancer Panel.

 

Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for hereditary cancer syndromes.

Clinical Information

Hereditary cancer syndromes account for approximately 5% to 10% of cancer cases.(1,2) Determining if there is a genetic risk factor contributing to cancer in an individual or family can be useful for tailoring surveillance plans, consideration of prophylactic risk reducing interventions, consideration of targeted treatments, and determining risk for family members.(3-9)

 

This panel evaluates 36 genes known to be associated with an increased risk of polyposis and several common cancers, including breast, colon, gastric, ovarian, pancreatic, prostate, skin, thyroid, and endometrial cancers. The risk for developing cancer, as well as other features associated with these syndromes, varies. Many of the genes on this panel have established cancer risk and National Comprehensive Cancer Network or expert group guidelines and recommendations for management.(3-8)

 

Indications for testing include but are not limited to:

-Individuals with multiple primary cancers

-Individuals with cancer diagnosed at young ages

-Individuals with a family history of multiple relatives with cancer

-Individuals whose family history of cancer may seem to overlap with more than one hereditary cancer syndrome

Reference Values

An interpretive report will be provided.

Interpretation

All detected variants are evaluated according to American College of Medical Genetics and Genomics recommendations.(1) Variants are classified based on known, predicted, or possible pathogenicity and reported with interpretive comments detailing their potential or known significance.
