Previous genomic analyses of glioblastoma have identified some molecular markers, including epidermal growth factor receptor (EGFR), platelet-derived growth factor receptor alpha (PDGFRA), vascular endothelial growth factor (VEGF), insulin-like growth factor 1 (IGF-1), P53 and isocitrate dehydrogenase 1 (IDH1), and X-linked alpha thalassemia mental retardation syndrome gene (ATRX) [3, 4]. The gene discussed is IDH1; the disease is glioblastoma.
