The more relevant molecular markers incorporated in glioma classification are IDH mutations, 1p19q deletion, MGMT promoter methylation, TERT promoter mutations, ATRX loss of function mutations, and p53 loss of function mutations and mutations in isocitrate dehydrogenase 1 and 2 genes (IDH1/2 m) (Louis et al., 2016). This evidence concerns the gene TERT and glioma.
