Breast cancer (BC) refers to multifactorial polygenic diseases that occur as a result of the combined interaction of genetic and environmental factors. Glutathione-mediated detoxification is of key importance in ensuring the resistance of body cells to the damaging effect of xenobiotics.</p><p><bold>Objective</bold>: to study the prevalence of deletion polymorphisms of the GSTM1 and GSTT1 genes and to establish their influence on the formation of cancer risk in patients with BC in the Primorye region (Russia).</p><p><bold>Materials and methods</bold>. The study involved 176 women with BC, aged 23 to 79 years (mean age 48 ± 13 years) and 66 conditionally healthy individuals without cancer. The detection of deletion (null) genotypes of the GSTM1 and GSTT1 was carried out using multiplex PCR followed by analysis of the melting curves of the reaction products.</p><p><bold>Results</bold>. The frequency of GSTT1-0 genotype among BC patients was higher than in the control group (14.77 % versus 6.06 %), significantly exceeding the indicators in the control group by more than 2.5 times (p &lt;0.1), indicating an association between the carriage of the GSTT1-0 genotype and the risk of developing BC. At the same time, the frequencies of the GSTM1-0 genotype in the study groups were comparable; no statistically significant association with the risk of developing BC was found.</p><p><bold>Conclusions</bold>. Homozygous deletion of GSTT1 (GSTT1-0) can potentially be considered as a low-penetrant risk factor for developing BC in the population of Primorye region.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Рак молочной железы (РМЖ) относится к мультифакториальным полигенным заболеваниям, реализующимся в результате сочетанного взаимодействия генетических и средовых факторов. Ключевое значение в обеспечении устойчивости клеток организма к повреждающему действию ксенобиотиков имеет глутатион-опосредованная детоксикация.</p><p><bold>Цель работы</bold> – изучение распространенности делеционных полиморфизмов генов <italic>GSTM1</italic>, <italic>GSTT1</italic> и установление их влияния на формирование онкологического риска у пациенток с РМЖ в Приморском крае.</p><p><bold>Материалы и методы</bold>. Обследовано 176 женщин с диагнозом РМЖ в возрасте от 23 до 79 лет (средний возраст – 48 ± 13 лет) и 66 условно здоровых лиц без злокачественных новообразований. Детекцию делеционных («нулевых») генотипов <italic>GSTM1</italic> и <italic>GSTT1</italic> осуществляли с помощью мультиплексной полимеразной цепной реакции с последующим анализом кривых плавления продуктов реакции.</p><p><bold>Результаты</bold>. Частота «нулевого» генотипа <italic>GSTT1</italic> среди больных РМЖ была выше, чем в группе контроля (14,77 % против 6,06 %), превышая показатели в группе контроля более чем в 2,5 раза (<italic>p</italic> &lt;0,1), что указывает на связь между носительством генотипа <italic>GSTT1</italic>-0 и риском развития РМЖ. В то же время частота встречаемости генотипа <italic>GSTM1</italic>-0 в исследуемых группах была сопоставимой, статистически значимой ассоциации с риском развития РМЖ не выявлено.</p><p><bold>Выводы</bold>. Гомозиготная делеция <italic>GSTT1</italic> (<italic>GSTT1</italic>-0) потенциально может рассматриваться как низкопенетрантный фактор риска развития РМЖ в популяции в Приморском крае.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>genetic polymorphism</kwd><kwd>GSTT1, GSTM1 genes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>генетический полиморфизм</kwd><kwd>гены <italic>GSTT1</italic>, <italic>GSTM1</italic></kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Malignant tumors in Russia in 2018 (incidence and mortality).
