PTEN Mutation Associated Tumors

The PTEN (phosphatase and tensin homolog) gene typically provides the body with instructions for making a protein that acts as a tumor suppressor by telling cells when they should stop growing and dividing. When there is a mutation in this gene, it can cause a number of health conditions, including Bannayan-Riley-Ruvalcaba syndrome and Cowden syndrome, which are often considered together as PTEN hamartoma tumor syndrome.
