People with TP53 mutations have Li-Fraumeni syndrome (LFS). TP53 is often also called by its older name “p53.”. 3. Cancer risks. WebDefinition. p53, also known as a tumour suppressor protein, is a gene that codes for a protein found in the nucleus of all cells in the body that helps regulate normal cell growth and multiplication. It is also plays a critical role in suppressing tumours by inhibiting the division and growth of cells whose DNA has been damaged.
