Genes that normally restrain cell growth but, when missing or inactivated by mutation, allow cells to grow uncontrolled.: Definition from: Office of Rare Diseases at the National Institutes of Health
A tumor suppressor gene directs the production of a protein that is part of the system that regulates cell division. The tumor suppressor protein plays a role in keeping cell division in check. When mutated, a tumor suppressor gene is unable to do its job, and as a result uncontrolled cell growth may occur. This may contribute to the development of a cancer.: Definition from: Talking Glossary of Genetic Terms from the National Human Genome Research Institute
