Detection of MID for rhabdomyosarcoma included myogenins, MyoD1 and PAX-FOXO1 fusion transcript, for synovial sarcoma—Bcl-2 protein and SYT-SSX fusion transcript, for clear cell sarcoma—S100 and melanoma cocktail and EWS-ATF1 fusion transcript by IHC and RT-qPCR [34]. Here, MYOD1 is linked to clear cell sarcoma.
