Universal tumor suppressor associated with many cancer types

Gene Overview

The TP53 gene is well-known tumor suppressor gene that has been implicated in many cancer types. (Wang, et al. 2018) The TP53 protein product is involved in regulating the cell cycle pathway and can prevent replication if cell damage has occurred. (Hampp, et al. 2016) Deletions, LOH, and loss of function (LOF) mutations have been associated with TP53. These alterations often confer a poor prognosis [CITE] and chemoresistance [CITE].
