Diagram of pie charts showing the frequency of RAS gene mutations in selected human cancers. The overall frequency of all RAS mutations found in each cancer subtype is indicated in parentheses (%), with specific percentage of each RAS gene that is mutated indicated with the pie charts. Data were compiled from the Cancer Cell Line Encyclopedia (CCLE) Exit Disclaimer; the International Cancer Genome Consortium (ICGC) Exit Disclaimer; and The Cancer Genome Atlas Data Portal (TCGA). The data are also available on the table below titled “Frequency of RAS Gene Mutations.”
