Targeted testing for familial variants (also called site-specific or known mutation testing) is available under FMTT / Familial Variant, Targeted Testing, Varies. Call 800-533-1710 to obtain more information about this testing option.

Shipping Instructions

Specimen preferred to arrive within 96 hours of collection.

Necessary Information

Molecular Genetics: Hereditary Custom Gene Panel Patient Information is strongly recommended. Testing may proceed without the patient information; however, it aids in providing a more thorough interpretation. Ordering providers are strongly encouraged to complete the form and send it with the specimen.

Clinical Information

This test can be used to customize genetic testing panels offered at Mayo Clinic Laboratories. Individual genes can be added or removed to an existing genetic testing panel. Additionally, this test can be used to create your own custom single gene or multi-gene panel or to combine existing panels within the same disease state.

Note: Any genes added to the custom panel must be from the same disease state. Only one Gene List ID may be submitted per Custom Gene Panel, Hereditary order. The Gene List ID can be created using the Custom Gene Ordering tool (see Ordering Guidance).

Reference Values

An interpretive report will be provided.

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Test Classification

This test was developed and its performance characteristics determined by Mayo Clinic in a manner consistent with CLIA requirements. It has not been cleared or approved by the US Food and Drug Administration.

CPT Code Information

CPT codes are based on the gene content of the custom gene panel. Refer to the Custom Gene Ordering Tool for custom gene panel specific CPT code information.
