Fluorescence In Situ Hybridization (FISH)
This test detects rearrangements involving the TFEB gene region (6p21) via fluorescence in situ hybridization (FISH) in formalin-fixed, paraffin-embedded tissue specimens. FISH is performed using a dual-color break-apart probe (Empire Genomics) to qualitatively assess for the presence of TFEB translocations that are associated with certain subtypes of renal cell carcinoma. Testing for TFEB gene rearrangement may aid in the diagnosis and classification of these tumors.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
This test detects rearrangements involving TFEB, however it will not identify the translocation partner.
- TFEB gene region 6p21
- FFPE FISH for TFEB
- Renal Cell Carcinoma
Submit a formalin-fixed, paraffin block of the renal tumor tissue (with matched benign renal tissue if available); store at room temperature.
