Mutation

Similar term(s): gene mutation, genetic mutation, chromosomal mutation.

Any permanent change in the DNA of a cell.

Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.

Mutations can be harmful, beneficial, or have no effect. If they occur in cells that make eggs or sperm, they can be inherited; if mutations occur in other types of cells, they are not inherited.

Certain mutations may lead to cancer or other diseases.
