TP53 and gastric carcinoma: PCR-Taqman assays identified the Arg/Pro genotype of the p53 codon 72 polymorphism in 140 patients with gastric carcinoma from the GanSu province in China, where the GC incidence is high, and the p53 codon 72 Pro carrier genotype with H. pylori infection was consistently higher in GC groups than controls [57].
