<p>A <b>tumor suppressor gene</b> (<b>TSG</b>), or <b>anti-oncogene</b>, is a <a href="page.php?w=gene">gene</a> that regulates a <a href="page.php?w=cell_%28biology%29">cell</a> during <a href="page.php?w=cell_division">cell division</a> and <a href="page.php?w=Self-replication">replication</a>. When a tumor suppressor gene is <a href="page.php?w=Mutation">mutated</a>, it results in a loss or reduction in its function. In combination with other genetic mutations, this could allow the cell to grow abnormally. The <a href="page.php?w=Loss-of-function_mutation">loss of function</a></p><p>
