В исследование включено 106 больных РМЖ из Национального центра онкологии им. В.А. Фанарджяна (Ереван, Республика Армения) и 117 пациенток с РМЖ и РЯ армянского происхождения, которые были направлены в НМИЦ онкологии им. Н.Н. Петрова (Санкт-Петербург) из нескольких онкологических диспансеров России (Краснодар, Сочи, Пятигорск). Анализ кодирующих последовательностей генов BRCA1 и BRCA2 выполнялся методом таргетного высокопроизводительного секвенирования.</p></sec><sec><title>Результаты</title><p>Результаты. В группе больных РМЖ из Еревана выявлено 16/106 (15 %) носительниц патогенных вариантов BRCA1/2 (BRCA1: n=9, BRCA2: n=7). Единственной повторяющейся мутацией оказался нонсенс-вариант BRCA1 c.5444G&gt;A [W1815X], составляющий 44 % всех выявленных патогенных аллелей. У пациенток армянского происхождения из России патогенные варианты BRCA1/2 были обнаружены у 16/117 (14 %) человек (BRCA1: n=6, BRCA2: n=10). В группе пациенток с РМЖ доля образцов с мутациями составила 13 %, а у больных РЯ – 19 %. 75 % патогенных аллелей были представлены пятью повторяющимися мутациями: BRCA1 c.2649_2650insGGCA, BRCA2 c.2808_2811delACAA, BRCA1 c.4065_4068delTCAA, BRCA2 c.9027delT и BRCA2 c.8437G&gt;T [G2813X]. Показано независимое происхождение патогенного варианта BRCA2 c.2808_2811delACAA у пациенток армянского и неармянского происхождения.</p></sec><sec><title>Заключение</title><p>Заключение. Спектр мутаций BRCA1/2 у пациенток армянского происхождения из Еревана и южных регионов России имеет существенные различия, что следует учитывать при разработке диагностических программ.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to compare the spectra of pathogenic BRCA1 and BRCA2 variants in patients with hereditary breast cancer (BC) and ovarian cancer (OC) from two groups of ethnic Armenians: Yerevan and cities of southern Russia.</p><sec><title>Material and Methods</title><p>Material and Methods. 106 BC patients from the V.A. Fanardjian National Centre of Oncology (Yerevan, Republic of Armenia) and 117 BC and OC patients of Armenian origin who were referred to the Petrov National Medical Centre of Oncology (St. Petersburg, Russia) from several cancer centers of Russia (Krasnodar, Sochi, Pyatigorsk) were included into the study. The coding sequences of BRCA1 and BRCA2 genes were analyzed by the method of targeted high-throughput sequencing.</p></sec><sec><title>Results</title><p>Results. Pathogenic variants of BCRA1 and BCRA2 genes were detected in 16/106 (BRCA1: n=9, BRCA2: n=7; 15%) BC patients from Yerevan. The only recurrent mutation was the BRCA1 nonsense variant c.5444G&gt;A [W1815X], accounting for 44% of all pathogenic alleles identified. In patients of Armenian origin from Russia, pathogenic BRCA1/2 variants were detected in 16/117 (14%) individuals (BRCA1: n=6, BRCA2: n=10). The proportion of samples with mutations was 13% in the group of BC patients and 19% in the group of OC patients. 75% of pathogenic alleles were represented by five recurrent mutations: BRCA1 c.2649_2650insGGCA, BRCA2 c.2808_2808_2811delACAA, BRCA1 c.4065_4068delTCAA, BRCA2 c.9027delT and BRCA2 c.8437G&gt;T [G2813X]. The independent origin of the pathogenic BRCA2 c.2808_2808_2811delACAA variant in Armenian and non-Armenian patients was shown.</p></sec><sec><title>Conclusion</title><p>Conclusion. A significant difference in the spectrum of BRCA1/2 mutations between Armenian patients from Yerevan and patients from southern regions of Russia was found. This should be taken into account when developing diagnostic programs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>рак яичника</kwd><kwd>наследственный опухолевый синдром</kwd><kwd>эффект родоначальника</kwd><kwd>молекулярно-генетическое исследование</kwd><kwd>молекулярная онкология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>ovarian cancer</kwd><kwd>hereditary cancer syndrome</kwd><kwd>founder effect</kwd><kwd>molecular genetics</kwd><kwd>molecular oncology</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантом РНФ [21-75-30015].</funding-statement><funding-statement xml:lang="en">This work was supported by the Russian Science Foundation [grant number 21-75-30015].</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sokolenko A.P., Sokolova T.N., Ni V.I., Preobrazhenskaya E.V., Iyevleva A.G., Aleksakhina S.N., Romanko A.A., Bessonov A.A., Gorodnova T.V., Anisimova E.I., Savonevich E.L., Bizin I.V., Stepanov I.A., Krivorotko P.V., Berlev I.V., Belyaev A.M., Togo A.V., Imyanitov E.N.
