Hereditary Oncology Testing

Test in Focus

In this "Test in Focus" episode of the "Answers From the Lab" podcast, Wei Shen, Ph.D., discusses Mayo Clinic Laboratories’ new hereditary oncology test offerings, which use next-generation sequencing to detect germline alterations associated with increased risk for various cancers. Our comprehensive panels, disease-specific panels, and single gene assays leverage the clinical expertise of Mayo Clinic physicians, enabling individualized insights on a patient’s risk of developing secondary cancers or a hereditary cancer syndrome.

“We know inherited genetic alterations contribute to about 10% to 20% of cancers overall,” Dr. Shen says. “However, more studies are showing that universal genetic testing actually detects more patients with hereditary cancer syndromes than a guideline-based approach.”

Test results can indicate the likelihood of a clinical diagnosis of a hereditary cancer syndrome, advance understanding of a patient’s risk of developing additional cancers, assist in management and treatment decisions, and rule out hereditary causes, Dr. Shen says. The biggest benefit of using Mayo Clinic testing, however, is access to expert-backed testing across the oncological spectrum.

“Cancers can result from both somatic and germline mutations,” Dr. Shen says. “This series of new genetic panels completes our comprehensive cancer testing menu and allows us to offer a one-stop shop genetic service to physicians and cancer patients.”
