New genetic technology allows a panel of multiple genes to be tested for mutations in a single test. In fact, the most recent NCCN guidelines allow that panel testing will largely replace sequential gene sequencing (i.e., the older approach of evaluating BRCA pathogenic variants first, then selecting additional genes if BRCA tests are negative).20,30,43 Surgeons, genetic counselors, and other health care professionals who order panel testing for breast cancer … Prior to the availability of panel gene tests for hereditary cancer, previous studies have examined the psychological ef-fects on patients of genetic testing for breast and ovarian can-cer, with conflicting results.

Ethical issues warrant consideration, as multiple gene panel testing has the potential to identify secondary findings not originally sought by the test requested. The Breast Cancer Comprehensive Panel examines 20 genes associated with an increased risk for hereditary breast cancer. Inherited predisposition to breast cancer is explained only in part by mutations in the BRCA1 and BRCA2 genes. National Cancer Institute.

These can effectively evaluate BRCA1/2 in addition to up to 43 other cancer-related genes. The genetic testing for cancer risk that is typically ordered by a doctor involves testing for inherited genetic variants that are associated with a high to moderate increased risk of cancer and are responsible for inherited cancer susceptibility syndromes. NCI CPTC Antibody Characterization Program. Accuracy of current guidelines for genetic testing of breast cancer patients has become a topic of debate due to two studies suggesting these guidelines may miss half the patients with pathogenic variants or genetic mutations. Breast cancer predisposition gene panel tests have a greater diagnostic yield than conventional testing of only the BRCA1 and BRCA2 genes. doi: 10.15761/ICST.1000228.
