Single-gene and single-site tests

There are some instances where single-gene or single syndrome testing may be preferred over a larger genetic testing panel. This is especially true when a patient’s diagnosis or family history is very suggestive for a certain syndrome or there is known familial variant.

Single-site test

Single-site testing is available when there is a known variant in the family. This test is available for any of the 66 genes on our Comprehensive Hereditary Cancer Panel.

Single-gene test

We have added single-gene tests for specific instances when a patient's personal and/or family history points to a specific gene instead of a broader evaluation.
