Test ID: FUS    
Low-Grade Fibromyxoid Sarcoma (LGFMS), 16p11 (FUS or TLS) Rearrangement, FISH, Tissue

Method Description Describes how the test is performed and provides a method-specific reference

This test uses a commercially available FUS dual-color break-apart probe (BAP) strategy. Formalin-fixed, paraffin-embedded tissues are cut at 5 microns and mounted on positively-charged glass slides. The selection of tissue and the identification of target areas on the hematoxylin and eosin (H and E)-stained slide is performed by a pathologist. Using the H and E slide as a reference, target areas are etched with a diamond-tipped etcher on the back of the unstained slide to be assayed. The probe set is hybridized to the appropriate target areas and 2 technologists each analyze 50 interphase nuclei each (100 total) with the results expressed as a percent abnormal nuclei.(Unpublished Mayo method)
