  • Clinical management of SCG is currently drawn from experience with intracranial gliomas. Our results identify unique molecular features of SCG suggesting an underlying biology distinct from intracranial gliomas.
  • In SCG, H3F3A mutations are exclusive to high grade while BRAF fusions are exclusive to low grade; SCG rarely harbor canonical intracranial alterations such as IDH1, EGFR or MGMTme; and SCG have greater penetration of DCs with less penetration of monocytes.
  • We provide a biological explanation for limited effectiveness of current therapies in SCG with potential implications for chemotherapy, targeted and immunotherapy. Our work underscores the need for investigations dedicated uniquely to SCG
