The investigators analyzed 32 virus subtype A samples obtained in 2002-2007. Polymorphism at the codons associated with IN resistance to chemicals was observed in 7 virus variants. The found substitutions had a pattern of genetic polymorphism and were unassociated with resistance in 6 patients with the test subtype A population. At the same time, minor RAL resistance mutation was revealed in 1 (3.1%) virus variant while the similar mutations in the subtype G population were about 10%.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены данные изучения генетического полиморфизма гена pol, кодирующего вирусную интегразу (ИН), популяции ВИЧ-1 субтипа А, циркулирующей на территории Липецкой области. В работе исследовали 32 образца вируса субтипа А, полученных за период 2002-2007 гг. Полиморфизм в кодонах, связанных с формированием устойчивости ИН к химиопрепаратам, наблюдали у 7 вариантов вируса. У 6 пациентов исследуемой популяции обнаруженные замены имеют характер генетического полиморфизма и не связаны с устойчивостью. При этом только у 1 (3,1%) варианта вируса выявлена минорная мутация устойчивости к RAL, в то время как аналогичные мутации в популяции субтипа G составляют около 10%.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Raltegravir</kwd><kwd>Elvitegravir</kwd><kwd>genetic polymorphism</kwd><kwd>HIV infection</kwd><kwd>integrase</kwd><kwd>subtype A</kwd><kwd>subtype G</kwd><kwd>raltegravir</kwd><kwd>elvitegravir</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>генетический полиморфизм</kwd><kwd>ВИЧ-инфекция</kwd><kwd>интеграза</kwd><kwd>субтип А</kwd><kwd>субтип G</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Гафарова И.
