Figure 3: Identification of novel candidate driver genes.

From: Comprehensive molecular profiling of lung adenocarcinoma

Figure 3

a, GISTIC analysis of focal amplifications in oncogene-negative (n = 87) and oncogene-positive (n = 143) TCGA samples identifies focal gains of MET and ERBB2 that are specific to the oncogene-negative set (purple). b, TP53, KEAP1, NF1 and RIT1 mutations are significantly enriched in samples otherwise lacking oncogene mutations (adjusted P < 0.05 by Fisher’s exact test). c, Co-mutation plot of variants of known significance within the RTK/RAS/RAF pathway in lung adenocarcinoma. Not shown are the 63 tumours lacking an identifiable driver lesion. Only canonical driver events, as defined in Supplementary Fig. 9, and proposed driver events, are shown; hence not every alteration found is displayed. d, New candidate driver oncogenes (blue: 13% of cases) and known somatically activated drivers events (red: 63%) that activate the RTK/RAS/RAF pathway can be found in the majority of the 230 lung adenocarcinomas.
