Signal Transducer and Activator of Transcription 6 (STAT6), Technical Component Only
Use
This test is useful for aiding in distinguishing solitary fibrous tumors from morphologic mimics. STAT6 is a signal transducer/transcription activator expressed in the cytoplasm of various normal tissues and its aberrant strong nuclear expression is associated with solitary fibrous tumors due to NAB2-STAT6 fusions.
Special Instructions
Not provided.
Limitations
This test does not include pathologist interpretation, only the technical performance of the stain. Age of a cut paraffin section can affect immunoreactivity and stability thresholds vary among published literature and are antigen dependent. Best practice is for paraffin sections to be cut within 6 weeks. Environmental factors can affect the charge of glass slides, potentially leading to inconsistent staining due to poor slide surface chemistry.
