Another study comparing uterine leiomyoma and leiomyosarcoma found that a small percentage (3 out of 56) of leiomyoma cases showed a RAD51B fusion (with HMGA2, NCOR2, and NUDT3), and one of these cases with RAD51B::NUDT3 fusion is reported here in detail [18]. The gene discussed is NUDT3; the disease is leiomyosarcoma.
