Moreover, neocortical WHO grade 3 gliomas exhibited higher rates of TERT promoter mutation and 1p/19q co-deletion (TERT promoter-mutant: 66.7% vs. 12.5%, p < 0.05; 1p/19q-codeleted: 66.7% vs. 12.5%, p < 0.05) (Figure 3c) (Table 4). The gene discussed is TERT; the disease is central nervous system cancer.
