Nebozhyn et al. proposed a panel of five genes (STAT4, GATA3, PLS3, CD1D, and TRAIL), Michel et al. proposed a panel of 4 genes (PLS3, Twist1, CD158k/KIR3DL2, and NKp46) using qRTPCR showing the ability to diagnose 91 and 100% cases of SS, respectively (57, 58). Here, TWIST1 is linked to synovial sarcoma.
