Introduction. The most common among occupational diseases in Ukraine are diseases of the bronchopulmonary system. In the structure of harmful and dangerous workrelated and occupational factors there are available diseases, which can cause disorders in the system of DNA repair and inducing mutagenesis.
Purpose of the study was to investigate the distribution of frequencies of alleles and genotypes of the repair gene XPD (rs799793) in patients with pathology of the bronchopulmonary system in workers of dusty professions at cement enterprises and coal mines of Ukraine.
Materials and methods. The study covered two categories of workers: workers of the cementconcrete enterprises of Ukraine (n = 92) and coal miners (n = 98). A realtime polymerase chain reaction method was used to determine genotypes of the XPD gene (rs799793). The results were statistically processed using programs of Orion 7.0, Statistica, and Excel 2000. Results. The frequencies of genotypes of XPD gene (rs799793) were established in occupational groups of miners and workers of the cement industry of Ukraine. The OR value of the minor allele XPD*Asn in workers of the cement enterprises indicated the correlation of disorders in the excitatory repair system of nucleotides with the risk of bronchopulmonary pathology development (OR = 1.34, 95 % CI: 0.69–2.59), whereas the dominant XPD*Asp allele promoted a protective actiont for its carriers (OR = 0.75, 95 % CI: 0.39–1.44). When studying the frequencies of genotypes of the XPD gene (rs799793) it is established that the XPD*Asn/Asn genotype is associated with a risk of the bronchopulmonary pathology and the inhibition of the efficiency of the excision repair of nucleotides in the population of workers at Ukrainian cement plants (OR = 2.15, 95% CI: 1.71–2.70, p ≤ 0.01, c2 = 6.35). Conclusions. As a result of the molecular genetic study of polymorphism of the XPD gene (rs799793) it was established that the XPD*Asn/Asn genotype was associated with the risk of developing the bronchopulmonary pathology and suppressing the efficiency of the excision repair of nucleotides in the population of workers at cementconcrete enterprises of Ukraine. Among the employees of the asbestocement enterprises the carriers of allele XPD*Asn promoted the increased risk of development of the bronchopulmonary pathology, and the carriage of allele XPD*Asp caused a protective actiont on development of the above pathology.
