Renal Cell Carcinoma, 6p21.1 (TFEB) Rearrangement, FISH, Tissue
Use
This test is useful for identifying TFEB gene rearrangements, supporting the diagnosis of renal cell carcinoma when used in conjunction with an anatomic pathology consultation. TFEB gene rearrangements are associated with renal cell carcinoma and the fluorescence in situ hybridization (FISH) methodology allows for the detection of these rearrangements to aid in diagnosis.
Special Instructions
A pathology report is required for testing. Acceptable reports include working drafts, preliminary pathology, or surgical pathology reports. The reason for testing must be provided. Reflex tests may incur additional charges based on the result and interpretation of the initial tests.
Limitations
This test is not FDA-approved and should be used as an adjunct to existing clinical and pathologic information. The test does not exclude other chromosome abnormalities and does not guarantee successful results on non-formalin fixed or decalcified tissue, with the latter having a success rate of about 50%. Probe application and analysis might incur additional charges, based on the number of cells analyzed. If no cells are available, no charges will be incurred. Ancillary probes may be performed at discretion for a comprehensive assessment.
