Внедрению же в клиническую практику фармакогенетического тестирования в определенном регионе должны предшествовать популяционно-генетические исследования. Цель исследования: Цель исследования состояла в анализе популяционно-генетической структуры популяций русских, татар и башкир, проживающих в Республике Башкортостан, по аллельным вариантам генов GSTM1, GSTT1, GSTP1, CAT, GPX1, NQO1. Материалы и методы: Материалом для исследования послужили образцы ДНК русских (N=640), татар (N=462) и башкир (N=192), проживающих в Республике Башкортостан. ДНК выделяли из образцов цельной венозной крови стандартным методом фенольно-хлороформной экстракции. Генотипирование проводили с помощью ПЦР, ПЦР-ПДРФ.&amp;nbsp; Статистическую обработку результатов выполняли с помощью пакета программ MS Office Excel 2003, STATISTICA v.6.0.&amp;nbsp; и программы Haploview 4.2. Результаты: Выявлены существенные межэтнические различия по распределению частот аллелей полиморфных маркеров генов GSTM1 (Del), GSTP1 (rs1695) и NQO1 (rs1800566). Установлено сходство популяций русских, татар и башкир по распределению частот аллелей полиморфных маркеров генов GSTT1 (Del), CAT (rs1001179). Анализ данных с привлечением литературных сведений показал сходство изученных популяций с населением Европы по спектру частот аллелей и генотипов полиморфных маркеров генов GSTM1(Del), GSTT1 (Del), NQO1 (rs1131341), с населением Азии по спектру частот аллелей и генотипов гена GSTP1 (rs1695). Заключение: Распределение частот аллелей полиморфных маркеров генов GSTM1 (del), GSTP1 (rs1695l) и NQO1 (rs1800566) имеет существенные межэтнические различия.&amp;nbsp; Распределение частот аллелей полиморфных маркеров генов GSTT1, CAT, GPX1 в популяциях русских, татар и башкир сходно.</p></abstract><trans-abstract xml:lang="en"><p>Background:&amp;nbsp;The ideal dose of drugs varies widely among patients, mainly due to genetic factors. Introduction to clinical practice of pharmacogenetic testing in a certain region should be preceded by population-genetic studies. The aim of the study:&amp;nbsp;To determine the prevalence of the most common allelic variants of GSTM1, GSTT1, GSTP1, CAT, GPX1, NQO1 in a representative sample of the three ethnic groups (Russians, Tatars, and Bashkirs) from the Republic of Bashkortostan (Russia), and to compare the results with existing data for other populations. Materials and methods:&amp;nbsp;The genotypes were determined in 1294 DNA samples of healthy unrelated individuals, representatives of three ethnic groups (Russians (N=640), Tatars (N=462) and Bashkirs (N=192)). The gene polymorphisms were examined using PCR and PCR-RLFP methods. Results:&amp;nbsp;The analysis of the GSTM1 (Del), GSTP1 (rs1695), and NQO1 (rs1800566) allele and genotype frequencies revealed significant differences among healthy residents of the Republic of Bashkortostan of different ethnicities.&amp;nbsp;Distribution of allele and genotype frequencies of the GSTT1 (Del), CAT rs1001179) genes were similar in Russians, Tatars, and Bashkirs. The analysis of literature data showed similarity of ethnic groups with the population of Europe in alleles and genotypes of polymorphic markers of the GSTM1 (Del), GSTT1 (Del), NQO1 (rs1131341) genes. The distribution of alleles and genotypes of the GSTP1 (rs1695l) gene were similar of the studied ethnic groups with the population of Asia are shown. Conclusion:&amp;nbsp;The frequency distribution of the alleles of polymorphic markers of the GSTM1 (del), GSTP1 (rs1695l) and NQO1 (rs1800566) genes has significant interethnic differences. The frequency distribution of the alleles of the polymorphic markers of the GSTT1, CAT, GPX1 genes in the populations of Russians, Tatars and Bashkirs is similar.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфные маркеры</kwd><kwd>гены ферментов антиоксидантной защиты</kwd><kwd>этнические группы</kwd><kwd>фармакогенетика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>genes of antioxidant protection</kwd><kwd>polymorphic markers</kwd><kwd>ethnic group</kwd><kwd>ecological genetics</kwd><kwd>metabolism</kwd></kwd-group></article-meta></front><back><ack><p>Исследование частично поддержано Российским фондом фундаментальных исследований (проекты №17-44-020735, №18-015-00050); биологический материал (ДНК) для исследования взят из коллекция биологических материалов человека ИБГ УФИЦ РАН, поддержанной&amp;nbsp;программой биоресурсных коллекций ФАНО&amp;nbsp;России (соглашение №007-030164/2); работа выполнена с использованием оборудования ЦКП &amp;quot;Биомика&amp;quot; и УНУ &amp;quot;КОДИНК&amp;quot; (ИБГ УФИЦ РАН).</p></ack><ref-list><title>Список литературы</title><ref id="B1"><mixed-citation>&amp;nbsp;</mixed-citation></ref><ref id="B2"><mixed-citation>Клиническая фармакология: учебник / под ред.
