What is a Gene Mutation?
A gene mutation is a change in an organism’s genetic material. Gene mutations can occur for a variety of reasons, and have a range of effects, from benign to malignant. Benign mutations in genetic material explain why people look very different, for example, while cancer is caused by malignant genetic mutations. Using genetic testing, doctors and researchers can identify individual points in an organism’s DNA where a gene mutation has occurred, and learn more about the process of mutations.
