No significant difference was observed in the frequency of amplification of these genes in primary and secondary glioblastomas or in glioblastomas with and without IDH1 mutations, suggesting that amplification of PDGFRA, KIT and KDR may be implicated in the pathogenesis of a small fraction of both subtypes of glioblastoma.
