The most common mutations are deletions of one or more exons (about 70 % of cases), which disrupt the reading frame and lead to the synthesis of a shortened and non-functional dystrophin protein, which causes the breakdown of skeletal muscle fibers (rhabdomyolysis) and progressive muscle weakness. The disease clinically manifests at the age of 2–5 years and rapidly progresses to the loss of the ability to walk independently by 8–12 years and death in the second or third decade of life due to respiratory and cardiac failure.</p> <p>The authors present Russian experience in the use of a gene therapy drug for the treatment of Duchenne muscular dystrophy using the exon skipping method, exemplified by the only registered drug of this class in Russia for Duchenne muscular dystrophy therapy – viltolarsen (Viltepso®).</p></abstract><trans-abstract xml:lang="ru"><p>Прогрессирующая мышечная дистрофия Дюшенна – наиболее тяжелая форма наследственных миопатий у мальчиков, вызванная мутациями в гене <italic>DMD</italic>, расположенном на X-хромосоме в локусе Xp21.2–p21.1 и кодирующем белок дистрофин. Наиболее частыми мутациями являются делеции одного или нескольких экзонов (около 70 % случаев), нарушающие рамку считывания и приводящие к синтезу укороченного и нефункционального белка дистрофина, что вызывает распад скелетно-мышечных волокон (рабдомиолиз) и прогрессирующую мышечную слабость. Заболевание клинически манифестирует в возрасте 2–5 лет и быстро прогрессирует до потери способности к самостоятельной ходьбе к 8–12 годам и летального исхода на втором-третьем десятилетии жизни вследствие дыхательной и сердечной недостаточности.</p> <p>Авторы представляют российский опыт применения генотерапевтического препарата в лечении прогрессирующей мышечной дистрофии Дюшенна за счет пропуска 53-го экзона (экзон-скиппинг) на примере единственного зарегистрированного в России препарата этого класса – вилтоларсена (Вилтепсо®).</p></trans-abstract><kwd-group xml:lang="en"><kwd>Duchenne muscular dystrophy</kwd><kwd>DMD</kwd><kwd>exon skipping</kwd><kwd>antisense oligonucleotide</kwd><kwd>Viltepso®</kwd><kwd>viltolarsen</kwd><kwd>exon 53</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>прогрессирующая мышечная дистрофия Дюшенна</kwd><kwd>DMD</kwd><kwd>экзон-скиппинг</kwd><kwd>антисмысловой олигонуклеотид</kwd><kwd>Вилтепсо®</kwd><kwd>вилтоларсен</kwd><kwd>экзон 53</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">Kayukov I.G., Smirnov A.V., Emanuel V.L.
