In our analysis we found that TP53 was mutated in 4,250/12,531 (34%) of the TCGA cancer samples and 898/1,457 (61%) of cell lines, with some cancer types showing strong mutational frequency (such as ovarian, lung, and glioblastoma) and others much less so (Figures S2A and S2B). The gene discussed is TP53; the disease is glioblastoma.
