KRAS mutation
One of the most common cancer-driving mutations, found in lung, colon, and pancreatic cancers.
What it is
A KRAS mutation is a change in the KRAS gene, which is a set of instructions inside our cells. This gene helps control cell growth and division. When the KRAS gene is mutated, it can send incorrect signals, leading to uncontrolled cell growth and cancer.
How it works
In normal cells, the KRAS gene helps control cell growth by sending signals to other parts of the cell. When a KRAS mutation occurs, these signals can get mixed up, leading to cells growing and dividing too quickly. This can lead to the formation of tumors and cancer. In some cases, the mutation can also make cancer cells resistant to certain treatments.
Why it matters
Understanding KRAS mutations is important because they are found in many types of cancer, including lung, colon, and pancreatic cancer. Knowing whether a cancer has a KRAS mutation can help doctors choose the best treatment options. It can also help researchers develop new treatments that target this specific mutation.
