EPCAM gene Overview

Lynch syndrome 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
  • Individuals with mutations in EPCAM have a condition called Lynch syndrome. This condition is also known as Hereditary Non-Polyposis Colon Cancer (HNPCC).
  • Men and women with Lynch syndrome due to mutations in EPCAM have a high risk of developing colorectal cancer, often at young ages. Colorectal cancer in patients with Lynch syndrome develops from adenomatous polyps which progress to cancer more quickly than polyps in individuals who do not have Lynch syndrome.
  • Women with Lynch syndrome due to mutations in EPCAM have a high risk for developing endometrial and ovarian cancer, often at young ages.
  • Patients with Lynch syndrome due to mutations in EPCAM are also believed to have an increased risk of developing a wide variety of other cancers, including gastric, small bowel, urinary tract, hepatobiliary tract, brain (usually glioblastoma), sebaceous gland, and pancreatic. These risks may be more significant in patients with a family history of these cancers. Therefore, the general screening and management recommendations provided below should be modified based on individualized risk assessment and counseling.
  • An increased risk for prostate cancer has been documented in multiple studies of men with Lynch syndrome. Estimates range from an approximately 2 to 5-fold increase in risk, or up to 30%, but the exact increase has not yet been established for men with mutations in EPCAM.
  • Studies have investigated the possibility that patients with Lynch syndrome have an increased risk for other cancers, including breast cancer and adrenocortical carcinoma. However, the data are not conclusive at this time and there are currently no medical management guidelines related to these cancers.
  • Patients with Lynch syndrome have a high risk for developing second primary cancers following an initial diagnosis of colorectal or endometrial cancer. This includes a high risk for endometrial cancer in women following colorectal cancer and vice versa, a high risk for a second primary colorectal cancer in any portions of the colon or rectum remaining after surgical treatment, and a high risk for other Lynch associated cancers, such as those of the upper gastrointestinal tract, urinary tract, and other sites.
  • Cancer risks for patients with Lynch syndrome due to mutations in EPCAM are currently estimated to be similar to those for patients with Lynch syndrome due to mutations in MSH2, and medical management guidelines are currently the same for patients with mutations in either gene. However, it is possible that this will change over time as we learn more about the exact risks associated with mutations in EPCAM. There are some early indications that endometrial cancer risk may be much lower for women with certain types of mutations in EPCAM.
  • Although there are high risks for cancer in patients with Lynch syndrome, many of these risks can be greatly reduced with appropriate medical management. Guidelines for the medical management of patients with Lynch syndrome have been developed by the National Comprehensive Cancer Network (NCCN) and other expert groups. These are listed below. It is recommended that patients with an EPCAM mutation and a diagnosis of Lynch syndrome be managed by a multidisciplinary team with expertise in medical genetics and the care of patients with this condition.

EPCAM Cancer Risk Management Table

The overview of medical management options provided is a summary of professional society guidelines. The most recent version of each guideline should be consulted for more detailed and up-to-date information before developing a treatment plan for a particular patient.

This overview is provided for informational purposes only and does not constitute a recommendation. While the medical society guidelines summarized herein provide important and useful information, medical management decisions for any particular patient should be made in consultation between that patient and his or her healthcare provider and may differ from society guidelines based on a complete understanding of the patient’s personal medical history, surgeries and other treatments.

Information for Family Members

The following information for Family Members will appear as part of the MMT for a patient found to have a mutation in the EPCAM gene.

A major potential benefit of myRisk genetic testing for hereditary cancer risk is the opportunity to prevent cancer in relatives of patients in whom clinically significant mutations are identified. Healthcare providers have an important role in making sure that patients with clinically significant mutations are informed about the risks to relatives, and ways in which genetic testing can guide lifesaving interventions.

Parents who are concerned about the possibility of passing on an EPCAM mutation to a future child may want to discuss options for prenatal testing and assisted reproduction techniques, such as pre-implantation genetic diagnosis (PGD).1
