RAS mutations are frequently found in cancer (∼24% of all cancers) (Stalnecker and Der 2020), where the K-RAS gene is mutated in approximately 17% of all cancer types (46,213 mutant samples/272047 samples tested), N-RAS gene is mutated in ∼5.1% (7,926 mutant samples/154172 samples tested), and H-RAS in ∼2.3% (2,404 mutant samples/106318 samples tested) (as reported in the Catalog of Somatic Mutated in Cancer, COSMIC database, v94, in August 2021). The gene discussed is KRAS; the disease is cancer.
