Various molecular aberrations of gliomas harbor valuable information for diagnosis, prognosis, or prediction, specifically comprising the combined loss of chromosome arms 1p and 19q, TP53 mutation, the incidence of isocitrate dehydrogenase 1 (IDH1) mutation, and the amplification of epidermal growth factor receptor (EGFR) and copy number aberrations of chromosomes 7 and 10 [3–6]. Here, EGFR is linked to glioma.
