The method of a polymerase chain reaction in the mode of “real time” with hybridizationaly-fluorescent detection carried out the analysis
of distribution of polymorphisms of genes p53 by G215C, p21 A1026G and G369C at patients with the gastric carcinoma and healthy donors. It
is established that an allele of C, genotypes of CC and GC of polymorphisms G215C of gene p53 and gene G369C p21, an allele of A and genotypes
of AA and GA of polymorphism of A1026G of gene p21 statistically are associated with the risk of carcinogenesis gastric.
