Validated sequencing results for 32 LGGs showing mutations in IDH1, ATRX, and TP53.1p/19q status, astrocytoma transcriptional subclass [21], and ALT FISH results are also shown along with patient age, primary/recurrent tumor status, and pathological diagnosis. WT: wild type, A: astrocytoma, O: oligodendroglioma, OA: oligoastrocytoma, II: WHO grade II, III: WHO grade III, NB: neuroblastic, EPL: early progenitor-like, PG: preglioblastoma. The gene discussed is TP53; the disease is neoplasm.
