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 Figure 6a,b). This evidence concerns the gene GNG4 and neoplasm.
