Спинальная мышечная атрофия 5q (СМА 5q) — самое частое аутосомно-рецессивное наследственное нервно-мышечное заболевание, для диагностики которого используют молекулярно-генетические исследования, позволяющие подтвердить только СМА 5q. Клиническая картина и результаты параклинических исследований могут перекрываться с наследственными первично-мышечными заболеваниями, затрудняя диагностику и отдаляя применение патогенетического лечения при СМА 5q.</p><p>Описание клинического случая. Приведено клиническое описание 10 больных с СМА 5q в возрасте от 3 мес до 25 лет с разной степенью выраженности проксимального тетрапареза, атрофией скелетной мускулатуры и угнетением сухожильных рефлексов. У 3 больных в возрасте до 2 лет с миогенным паттерном при игольчатой электромиографии (иЭМГ) в латеральной мышце бедра и у 7 больных старше 2 лет с повышением уровня креатинфосфокиназы (КФК) сыворотки крови ошибочно проводили поиск наследственных первично-мышечных заболеваний на протяжении периода от 1 мес до 12 лет. После медико-генетического консультирования на основании темпов течения заболевания и клинических признаков заподозрена и подтверждена СМА 5q.</p></sec><sec><title>Заключение</title><p>Заключение. При вялом проксимальном тетрапарезе в сочетании с миогенным паттерном при иЭМГ у детей раннего возраста или в комбинации с повышением КФК при позднем дебюте на первой линии необходимо проводить дифференциальную диагностику с СМА 5q в связи с возможностью патогенетического лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Spinal muscular atrophy 5q (5q SMA) is the most frequent autosomal recessive hereditary neuromuscular disease. Molecular genetic testing is used for SMA diagnosis, and it can confirm only 5q SMA. The clinical findings and results of paraclinical studies may overlap with hereditary primary-muscular diseases making the diagnosis difficult and delaying the administration of pathogenetic treatment for 5q SMA.</p><p>Clinical case description. Clinical description of 10 patients with 5q SMA aged from 3 months to 25 years with different severity of proximal tetraparesis, skeletal muscular atrophy and tendon reflexes depression is given. 3 patients under 2 years of age with myogenic pattern at needle electromyography (nEMG) in lateral vastus muscle and 7 patients over 2 years of age with increased levels of creatine phosphokinase (CPK) in blood serum were mistakenly diagnosed for inherited primary-muscular diseases for the period from 1 month to 12 years. After the genetic counselling based on the disease course and clinical findings we suspected and later confirmed 5q SMA.</p></sec><sec><title>Conclusion</title><p>Conclusion. In case of flaccid proximal tetraparesis associated with myogenic pattern at nEMG in young children or with increased CPK levels at late manifestation it is crucial to perform differential diagnosis of 5q SMA since there are options of pathogenetic therapy. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>спинальная мышечная атрофия</kwd><kwd>СМА 5q</kwd><kwd>ген SMN1</kwd><kwd>игольчатая ЭМГ</kwd><kwd>КФК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spinal muscular atrophy</kwd><kwd>5q SMA</kwd><kwd>SMN1 gene</kwd><kwd>needle EMG</kwd><kwd>CPK</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The article was funded by Johnson &amp; Johnson.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kolb SJ, Kissel JT.
