While leiomyosarcoma was the most common diagnosis, there was no clear unifying theme, and none showed sclerosing epithelioid fibrosarcoma-like histology as in YAP1–KMT2A fusion-positive sarcomas or small round blue cell-like histology in VIM–KMT2A fusion-positive sarcomas. This evidence concerns the gene YAP1 and sarcoma.
