摘要: Mutations in the genes encoding isocitrate dehydrogenase (IDH) 1/2 have been detected a significant proportion of diffuse gliomas and small fraction acute myeloid leukemia (AML) cases. Recently, an examination various types mesenchymal tumor, IDH1/2 mutations were only found cartilaginous tumors including central conventional periosteal enchondromas/chondrosarcomas. The frequency was 56%, IDH1 R132C mutation, which is not common or AML, accounted for 40% these mutations. In this study, we investigated mutation status intracranial chondrosarcomas chordomas, are morphologically similar affect regions cranial cavity. Of 13 analyzed, six (46.1%) displayed (the predominant type R132C). Also, IDH2 (R172S) observed one case. Conversely, none ten chordomas analyzed any Our data suggest that could be valuable distinguishing from chordomas.
