acquired mutation


uh-KWY-erd myoo-TAY-shun


A mutation (change) in DNA that starts in one cell of the body after a person is born. This mutation is then passed on to any new cells that arise from that cell. In some cases, acquired mutations can lead to cancer. This is different from inherited mutations, which are present at birth and in almost all the cells of the body. Acquired mutations are not passed on to children.
