Since its discovery in 1997, the p73 gene has attracted much attention from researchers. Studies have shown that, p73 and p53 protein has a very similar structure and function, but there is a difference between the two 犤 2 犦. The expression level of p73 gene and allele in different types of tumor cells are not the same. Although there is polymorphism in the coding region of p73 gene, so far no tumor has been found
