The results of the research on the polymorphism of DNA reparation genes in miners and workers of asbestos cement plants with the occupationally determined respiratory pathology are presented in the article.

Objective: We studied the distribution of the genotype frequencies of XRCC1 (rs25487) and XRCC3 (rs861539) genes in miners and workers of asbestos cement plants for the identification of the markers of the risk of the development of bronchopulmonary pathology.

Materials and methods: The workers of asbestos-cement plants and miners were engaged in the study. The real-time polymerase chain reaction was used to determine the genotypes of DNA reparation genes.

Results: It was established that the XRCC1*AA genotype was associated with the risk of bronchopulmonary pathology in the population of workers of the asbestos-cement plants and miners of Ukraine. The protective role of the genotype XRCC1*GA in relation to the risk of developing bronchopulmonary system diseases in workers of asbestos-cement plants in Ukraine has been established.
