DM1 is clinically manifested by a combination of myotonia, progressive atrophy of skeletal muscles, and the multisystemic character of the disorder, severity of which correlates with the CTG tract length. DM1 is characterized by anticipation that is manifested in the worsening and more early onset of the disease in each succeeding generation, especially when inherited from clinically affected mothers. Using clinical observation of a family with two cases of advansed DM1 forms as an example, it was demonstrated that clinical, electromyographic, and molecular genetic examinations of all first-degree relatives (parents, siblings, children) are required for the correct prognosis and genetic counseling.</p></abstract><trans-abstract xml:lang="ru"><p>Дистрофическая миотония 1 типа (ДМ1) – аутосомно-доминантное заболевание, связанное с экспансией тринуклеотидных CTG-повторов в гене миотонинпротеинкиназы (DMPK). Клинически ДМ1 проявляется сочетанием миотонии, прогрессирующей атрофии скелетной мускулатуры и полисистемным характером поражения, тяжесть которых коррелирует с длиной CTG-тракта. Для ДМ1 характерна антиципация, проявляющаяся утяжелением и более ранним дебютом болезни в каждом последующем поколении, особенно при наследовании от клинически больных матерей. На примере клинического наблюдения семьи с двумя случаями развернутых форм ДМ1 показана необходимость проведения клинического, электромиографического и молекулярно-генетического исследований всем родственникам первой степени родства (родители, сибсы, дети) для корректного прогноза заболевания и проведения медико-генетического консультирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mmyotonic dystrophy type 1</kwd><kwd>DMPK gene</kwd><kwd>CTG repeat expansion</kwd><kwd>anticipation</kwd><kwd>myotonic discharges</kwd><kwd>decrement of M-response amplitude</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дистрофическая миотония 1-го типа</kwd><kwd>ген DMPK</kwd><kwd>экспансия CTG-повторов</kwd><kwd>антиципация</kwd><kwd>миотонические разряды</kwd><kwd>декремент амплитуды М-ответа</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Гаусманова-Петрусевич И.
