Beyond that, aberrant Hippo signaling can arise from chromosomal translocations involving YAP1 or WWTR1 (encoding TAZ) as in epithelioid hemangioendothelioma, another fusion gene‐driven soft‐tissue tumor (Errani et al, 2011; Tanas et al, 2011, 2016; Antonescu et al, 2013). The gene discussed is WWTR1; the disease is epithelioid hemangioendothelioma.
