Despite the significant progress in investigation of genetic susceptibility to cancers, there are still unclear questions in the field of molecular epidemiology. Numerous new data obtained using modern sequencing technologies require large case/control studies in different populations.</p><p><bold>The study objective</bold> – to investigate the prevalence of <italic>BRCA1</italic>*c.5161C&gt;T mutation in unselected breast, ovarian and prostate cancer patients from Bashkortostan.</p><p><bold>Materials and methods</bold>. In the presented study, the prevalence of the <italic>BRCA1</italic>*c.5161C&gt;T mutation was assessed in breast cancer, ovarian cancer and prostate cancer patients (n = 696). The study cohorts includes individuals of Tatar and Bashkir ethnic origin living in Bashkortostan Republic.</p><p><bold>Results</bold>. The <italic>BRCA1</italic> mutation c.5161C&gt;T was detected in patients with breast cancer, ovarian cancer and prostate cancer in individuals of Tatar ethnic origin with a frequency of ~1,3 % (6/449), but not in Bashkirs. This mutation was also detected in two individuals of control group (2/700). We conclude that the contribution of the <italic>BRCA1</italic> mutation c.5161C&gt;T to hereditary breast, ovarian and prostate cancers, is likely to be small in Bashkortostan Republic.</p><p><bold>Conclusion</bold>. Further research will be required to investigate whether this mutation also plays a role in other populations of Turkic origin.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. На основании многочисленных эпидемиологических и лабораторных исследований в области молекулярной эпидемиологии достигнуты существенные успехи в изучении генетической предрасположенности злокачественных новообразований, но еще остается ряд нерешенных вопросов. Применение современных технологий секвенирования позволило получить новые данные, которые необходимо проанализировать с использованием популяционного подхода с вовлечением в работу больших по численности исследуемых групп.</p><p><bold>Цель исследования</bold> – оценить частоту мутации <italic>BRCA1</italic>*c.5161C&gt;T у пациентов с раком молочной, железы, яичников и предстательной железы, проживающих в Республике Башкортостан.</p><p><bold>Материалы и методы</bold>. В представленной статье проанализирована встречаемость мутации <italic>BRCA1</italic>*c.5161C&gt;T у пациентов с раком молочной железы, яичников и предстательной железы татарской и башкирской этнической принадлежности, проживающих в Республике Башкортостан (n = 696).</p><p><bold>Результаты</bold>. Мутация <italic>BRCA1</italic>*c.5161C&gt;T встречается у пациентов татарской этнической принадлежности с раком молочной железы, яичников и предстательной железы примерно в 1,3 % случаев (6/449); у пациентов-башкир она не обнаружена. Данная мутация также определена в контрольной выборке (2/700). Полученные результаты не подтверждают высокую частоту мутации <italic>BRCA1</italic>*c.5161C&gt;T у башкир.</p><p><bold>Заключение</bold>. В перспективе необходимы дальнейшие исследования для оценки частоты распространения данного варианта в других популяциях, населяющих Волго-Уральский регион России.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>ovarian cancer</kwd><kwd>prostate cancer</kwd><kwd>genes</kwd><kwd>mutation</kwd><kwd>genetic predisposition</kwd><kwd>ethnic</kwd><kwd><italic>BRCA1</italic></kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>рак яичников</kwd><kwd>рак предстательной железы</kwd><kwd>ген</kwd><kwd>мутация</kwd><kwd>генетическая предрасположенность</kwd><kwd>этническая принадлежность</kwd><kwd><italic>BRCA1</italic></kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was carried out within the framework of the state assignment of the Ministry of Education and Science of Russia (No. AAAAA16-116020350032-1), the Program for the development of Bioresource collections (No. 007-030164/2), and also with the use of the equipment of the Biomika Collective Use Center and the Unique scientific installation “KODINK”.</funding-statement><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России (№ АААА-А16-116020350032-1), Программы развития биоресурсных коллекций (№ 007-030164/2), а также с использованием оборудования Центра коллективного пользования «Биомика» и Уникальной научной установки «КОДИНК».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ferlay J., Colombet M., Soerjomataram I. et al.
