If the DNA damage can’t be repaired, TP53 prevents the cell from dividing and tells the cell to die. When the TP53 gene is mutated, it causes cells with damaged DNA to grow and divide out of control. TP53 gene mutations are common and happen in more than 50% of all cancers. WebMar 23, 2024 · Improperly functioning p53 genes allow cancer to spread faster and become more resistant to treatment.
