Expression-based clustering of cells for the patient-1 tumor sample resolved two HGSOC cell clusters, with fusion RAPGEF5::AGMO evident in tumor cells largely clustered separately from cells expressing SMG7::CH507-513H4.1 and GS1-279B7.2::GNG4, potentially reflecting tumor heterogeneity (Fig. 8A,B). The gene discussed is RAPGEF5; the disease is neoplasm.
