Tempus xG/xG+ Hereditary Cancer Germline Testing (Powered by GeneDx)

The xG and xG+ assays are validated hereditary cancer tests that detect various types of germline alterations associated with inherited cancer risk.

xG+ (extended hereditary cancers) includes an 88 gene DNA seq panel associated with both common and more rare hereditary cancer types.

xG (common hereditary cancers) includes a 52 gene DNA seq panel associated with six of the most common hereditary cancer types (breast, ovarian, colorectal, endometrial, prostate, pancreatic).

WHY HEREDITARY CANCER TESTING IS IMPORTANT

Up to 10% of all cancers are associated with hereditary cancer syndromes.1

Germline or hereditary cancer genetic testing can help determine whether there is a genetic variant being passed down in the family.

Indications for Hereditary Cancer Testing

TURNAROUND TIME

10–21 days from specimen retrieval

IDENTIFICATION OF INCIDENTAL GERMLINE FINDINGS

Patient’s xT tumor + normal matched testing identifies one or more germline variants in the normal sample and will report pathogenetic and likely pathogenic findings.

CONFIRMATORY GERMLINE TESTING

xG and xG+ provides validated germline testing to confirm incidental findings identified on somatic reports.

PATIENT IMPACT

Provides the opportunity for confirmatory testing in patients who may not otherwise qualify for germline testing based on age, family history, or tumor type.

The xG and xG+ tests may also be utilized to assess variants suspicious for germline presence detected on tumor only sequencing or liquid biopsy and to test for Lynch syndrome for MSI-High tumors.

Patient genetic counseling services are available through our partner, GeneDX Genetic Counseling. To request a genetic counseling consultation for your patient, please submit a completed referral form to support@tempus.com.
