Approximately 80% of families with the features of Li-Fraumeni Syndrome (LFS) have an identifiable change (mutation) in the TP53 gene. TP53 is a tumor suppressor gene, which means that it encodes a protein that helps keep cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in TP53 result in a defective protein that is unable to carry out its normal role. This leads to the development of the many different types of tumors found in LFS.
