Mutations of the p53 gene represent the most common genetic alterations in human cancer. Several reports have focused on p53 polymorphisms as risk factors in lung cancer, in particular at codon 72 of exon 4, encoding either an arginine (Arg72R) or a proline (Pro72P) amino acid. Polymorphisms at codon 72 of the p53 gene were determined using a PCR-RFLP-based method. We analysed the relationship ...
