To search for new targets of therapy, it is necessary to reconstruct the gene network of the disease, and identify  the interaction of genes, proteins, and drug compounds. Using the online bioinformatics tools we have analyzed  the current data set related to the metabolism of xenobiotics, mediated by the N-acetyltransferase 2 (NAT2) gene.  The study of allelic polymorphism of the NAT2 gene has a prognostic value, allowing to determine the risk of a number  of oncological diseases, the degree of increased risk due to smoking and exposure to chemical carcinogens, including  drugs. The aim of this study was to determine the frequencies of two important “slow” variants of the NAT2 gene  (NAT2*5, rs1801280 and NAT2*7, rs1799931), which significantly affected the rate of xenobiotic acetylation among  the indigenous Nenets population of Northern Siberia. The obtained frequencies of polymorphic variants  among the Nenets occupy an intermediate value between those for Europeans and Asians, which might indicate  specific features of adaptation. We present a model of the distribution of two polymorphic variants of the NAT2 gene  involved in the biotransformation of xenobiotics to study the characteristics of their metabolism in the indigenous  inhabitants of Yamal.
