Cancer Category/Type
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 [1]. The TP53 protein product is involved in regulating the cell cycle pathway and can prevent replication if cell damage has occurred [2]. Deletions, LOH, and loss of function (LOF) mutations have been associated with TP53. These alterations often confer a poor prognosis and chemoresistance.
