What is the KRAS gene?

KRAS is a gene that forms a protein in cell signaling pathways that control cell growth, cell maturation, and cell death. The natural, unaltered form of the gene is known as wild-type KRA. The mutated form of KRA is found in pancreatic cancer. These changes can cause cancer cells to grow and spread throughout the body. Knowing whether a patient's tumour has a wild type or a mutated KRA gene can help in planning cancer treatment. (Sources: cancer.gov )
