Tumor protein p53 (TP53) is a gene that codes for a tumor suppressor protein, cellular tumor antigen p53. The protein regulates expression of genes involved in cell cycle arrest, apoptosis, senescence, DNA repair, and changes in metabolism (Gene 2014). In cancer, TP53's normal roles are not fulfilled, leading to cell survival, DNA damage, and cell proliferation. TP53 is the most frequently mutated gene in cancer; it is mutated in about half of all cancers (Genetics Home Reference 2014). TP53 is most frequently mutated in ovarian, colon, and esophageal cancers, although it is significantly mutated in many other cancer types (COSMIC).

TP53 is altered in 39.49% of all cancers with non-small cell lung carcinoma, colorectal adenocarcinoma, breast carcinoma, ovarian neoplasm, and pancreatic exocrine neoplasm having the greatest prevalence of alterations [3].

The most common alterations in TP53 are TP53 Mutation (51.27%), TP53 Missense (37.33%), TP53 c.1-c.137 Missense (37.33%), TP53 c.142-c.212 Missense (37.33%), and TP53 c.217-c.1178 Missense (37.33%) [3].
