WebA tumor suppressor gene ( TSG ), or anti-oncogene, is a gene that regulates a cell during cell division and replication. [1] If the cell grows uncontrollably, it will result in cancer. When a tumor suppressor gene is mutated, it results in a loss or reduction in its function. WebCancer is caused by the malfunction of genes that regulate cell proliferation.
