As TAZ (the common name of the protein encoded by WWTR1 and not to be confused with Tafazzin whose gene name is TAZ) and its paralog YAP (encoded by YAP1) are the transcriptional effectors of the Hippo pathway (Zheng & Pan 2019), the discovery of these gene fusions in EHE suggested a new potential role for YAP and TAZ fusion proteins in cancer. The gene discussed is YAP1; the disease is cancer.
