Test Overview

Test Methodology

Fluorescence In Situ Hybridization (FISH)

Test Usage

This test detects rearrangements involving the TFE3 gene region (Xp11.2) 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 TFE3 translocations that are associated with certain subtypes of renal cell carcinoma. Testing for TFE3 gene rearrangement may aid in the diagnosis and classification of renal tumors.

Reference Range

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements

Offsite Collection Instructions

Submit a formalin-fixed, paraffin block of the renal tumor tissue (with matched benign renal tissue if available); store at room temperature.
