Test Code PRS8P Hereditary Prostate 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. 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 patients with a personal or family history suggestive of a hereditary prostate cancer syndrome

 

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

 

Identifying genetic variants associated with increased risk for prostate 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)

Clinical Information

Hereditary prostate cancer accounts for approximately 5% to 10% of all prostate cancer cases and up to half of all early-onset prostate cancer cases.(1-3) Evaluation of the genes on this panel may be useful for families with a history of prostate cancer to determine cancer risk, surveillance recommendations, and targeted treatments (such as poly adenosine diphosphate-ribose polymerase [PARP] inhibitor therapy).(4,5)

 

The 2 most common hereditary prostate cancer syndromes are hereditary breast and ovarian cancer (HBOC) syndrome and Lynch syndrome.(3-5)

 

HBOC syndrome is caused by disease-causing variants in the BRCA1 and BRCA2 genes. Individuals with HBOC syndrome are also at increased risk for multiple cancer types, including prostate cancer.(5)

 

Lynch syndrome is caused by variants in the MLH1, MSH2, MSH6, and PMS2 mismatch-repair genes and deletions of the EPCAM gene. A subset of these patients present with prostate cancer.(3-5)

 

This panel includes other genes known to increase prostate cancer risk.(3-5) The risk of developing cancer associated with these syndromes varies. Some individuals with a disease-causing variant in one of these genes develop multiple primary cancers.(4)

 

The National Comprehensive Cancer Network and the American Cancer Society provide recommendations regarding the medical management of individuals with hereditary prostate cancer syndromes.(4,5)
