Thus, mutated (m) KRAS represents a cancer driver oncoprotein, and KRAS codon 12 mutations are frequently found in pancreatic ductal adenocarcinomas (PDACs), colorectal adenocarcinomas (CRCs), and non-small-cell lung cancers (NSCLCs) [14–16]. The gene discussed is KRAS; the disease is pancreatic ductal adenocarcinoma.
