В этой работе описаны клинические наблюдения миотонической дистрофии 2 типа с манифестацией в возрасте до 18 лет. По мнению авторов, ознакомление с представленными случаями будет способствовать совершенствованию знаний об особенностях фенотипических проявлений и ранней диагностике этой патологии.</p></abstract><trans-abstract xml:lang="en"><p>Myotonic dystrophy type 2 is a multisystem neurodegenerative disorder with an autosomal dominant inheritance pattern, traditionally considered to have an onset in the 3rd or 4th decade of life. This paper describes clinical cases of myotonic dystrophy type 2 manifested before age of 18. The authors suppose that reviewing these cases will contribute to improved understanding of the phenotypic manifestations and early diagnosis of this disorder.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миотоническая дистрофия 2 типа</kwd><kwd>экспансия в гене СNBP</kwd><kwd>клинические проявления миотонической дистрофии 2 типа в детском возрасте</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myotonic dystrophy type 2</kwd><kwd>CNBP gene expansion</kwd><kwd>clinical manifestations of myotonic dystrophy type 2 in childhood</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ricker K., Koch M.C., Lehmann-Horn F. et al.
