HelpTest Code PANCP Hereditary Pancreatic Cancer Panel, Varies
Ordering Guidance
This test assesses for hereditary forms of pancreatic adenocarcinoma and not other pancreatic lesions such as pancreatic neuroendocrine tumors. For genetic testing for pancreatic neuroendocrine tumors, see ENDCP / Hereditary Endocrine Cancer Panel, Varies.
This test does not analyze genes associated with hereditary pancreatitis. For genetic testing for pancreatitis, see PANGP / Expanded Pancreatitis Gene Panel, Varies.
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. To modify this panel via CGPH, use the Hereditary Cancer disease state for step 1 on the Custom Gene Ordering Tool.
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.
Specimen Required
Patient Preparation: A previous hematopoietic stem cell transplant from an allogenic donor will interfere with testing. For information about testing patients who have received a hematopoietic stem cell transplant, call 800-533-1710.
Submit only 1 of the following specimens:
Specimen Type: Whole blood
Container/Tube: Lavender top (EDTA) or yellow top (ACD)
Specimen Volume: 3 mL
Collection Instructions:
1. Invert several times to mix blood.
2. Send whole blood specimen in original tube. Do not aliquot.
3. Whole blood collected postnatal from an umbilical cord is also acceptable. See Additional Information
Specimen Stability Information: Ambient (preferred) 4 days/Refrigerated 4 days/Frozen 4 days
Additional Information:
1. Specimens are preferred to be received within 4 days of collection. Extraction will be attempted for specimens received after 4 days, and DNA yield will be evaluated to determine if testing may proceed.
2. To ensure minimum volume and concentration of DNA are met, the requested volume must be submitted. Testing may be canceled if DNA requirements are inadequate.
3. For postnatal umbilical cord whole blood specimens, maternal cell contamination studies are recommended to ensure test results reflect that of the patient tested. A maternal blood specimen is required to complete maternal cell contamination studies. Order MATCC / Maternal Cell Contamination, Molecular Analysis, Varies on both the cord blood and maternal blood specimens under separate order numbers.

Specimen Type: Extracted DNA
Container/Tube:
Preferred: Screw Cap Micro Tube, 2 mL with skirted conical base
Acceptable: Matrix tube, 1 mL
Collection Instructions:
1. The preferred volume is at least 100 mcL at a concentration of 75 ng/mcL.
2. Include concentration and volume on tube.
Specimen Stability Information: Frozen (preferred) 1 year/Ambient/Refrigerated
Additional Information: DNA must be extracted in a CLIA-certified laboratory or equivalent and must be extracted from a specimen type listed as acceptable for this test (including applicable anticoagulants). Our laboratory has experience with Chemagic, Puregene, Autopure, MagnaPure, and EZ1 extraction platforms and cannot guarantee that all extraction methods are compatible with this test. If testing fails, one repeat will be attempted, and if unsuccessful, the test will be reported as failed and a charge will be applied. If applicable, specific gene regions that were unable to be interrogated due to DNA quality will be noted in the report.

All specimens will be evaluated at Mayo Clinic Laboratories for test suitability.Clinical Information
Pancreatic cancer occurs in approximately 1.6% of individuals.(1) About 10% of pancreatic cancers are caused by a hereditary predisposition that may also increase risk for other types of cancer.(2) In rare cases, individuals with a personal or family history of pancreatic cancer may be at increased risk of cancer due to a hereditary cancer syndrome. Evaluation of the genes on this panel may be useful to determine cancer risk, surveillance recommendations, and targeted treatments.(2,3)
A few of the most common hereditary pancreatic cancer syndromes are hereditary breast and ovarian cancer (HBOC) syndrome caused by variants in the BRCA1 and BRCA2 genes,(2,4) Lynch syndrome caused by variants in the MLH1, MSH2, MSH6, PMS2 mismatch-repair genes and deletions of the EPCAM gene, and melanoma-pancreatic cancer syndrome caused by variants in the CDKN2A gene.(2-5) Individuals with Peutz-Jeghers syndrome, caused by alterations within the STK11 gene, also have an increased risk of developing pancreatic cancer.(6)
Other genes are also known to cause hereditary pancreatic cancer. 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.(2)
The National Comprehensive Cancer Network and the American Cancer Society provide recommendations regarding the medical management of individuals with hereditary pancreatic cancer syndromes.(2,3,7)

Genetics Test Information
This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 12 genes associated with pancreatic cancer: ATM, BRCA1, BRCA2, CDKN2A, EPCAM (copy number variants only), MLH1, MSH2, MSH6, PALB2, PMS2, STK11, and TP53. For more information see Method Description and Targeted Genes and Methodology Details for Hereditary Pancreatic Cancer Panel.
Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for hereditary pancreatic cancer.
