Анализируются данные литературы и предложения Международной рабочей группы по диагностике альфа-маннозидоза. Представлены результаты обследования 15 больных с альфа-маннозидозом в возрасте от 1 года до 12 лет. Диагноз установлен на основании совокупности фенотипических признаков и крайне низкой активности лизосомального фермента альфа-маннозидазы в лимфоцитах периферической крови. У 14 пробандов проведена молекулярно-генетическая верификация диагноза. Установлено, что для всех наблюдавшихся нами больных был типичен гурлер-подобный фенотип, более легкий, чем при синдроме Гурлер. По тяжести заболевания дети были разделены на 2 группы: тяжелая (1 ребенок) и среднетяжелая (14 детей) формы. Болезнь имела прогредиентное течение.</p><p>Разработанная и зарегистрированная в странах Европы ферментозаместительная терапия препаратом велманаза альфа (рекомбинантная альфа-маннозидаза человека), в России, к сожалению, пока не применяется из-за отсутствия регистрации. Ранняя диагностика и раннее начало заместительной ферментная терапии — наилучший способ максимально ограничить прогрессирование заболевания, а эффективное медико-генетическое консультирование способствует его профилактике.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to a rare (orphan) disease from the group of lysosomal storage diseases — alpha-mannosidosis, associated with the accumulation of mannose-containing oligosaccharides in the tissues and cells of the body. The authors analyze the literature data and proposals of the International working group for the diagnosis of alpha-mannosidosis. The article presents the examination results of 15 patients with alpha-mannosidosis aged from 1 to 12 years. The diagnosis was based on the combination of phenotypic traits and extremely low activity of the lysosomal enzyme of alpha-mannosidase in peripheral blood lymphocytes. The molecular genetic verification of the diagnosis was performed in 14 probands. The authors found that all the patients under observation had a typical Hurler-like phenotype, lighter than patients with Hurler syndrome. The children were divided into 2 groups according to the severity of the disease: severe (1 child) and moderate (14 children) forms. The disease had a progressive course.</p><p>The enzyme replacement therapy with velmanase alpha (recombinant human alpha-mannosidase), developed and registered in the European countries, is not used in Russia due to the absence of registration. Early diagnosis and early start of enzyme replacement therapy is the best way to limit the progression of the disease, and effective genetic counseling helps to prevent it.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>редкие (орфанные) болезни</kwd><kwd>лизосомные болезни накопления</kwd><kwd>альфа-маннозидоз</kwd><kwd>клинические проявления</kwd><kwd>ген MAN2B1</kwd><kwd>заместительная ферментная терапия</kwd><kwd>велманаза альфа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>rare (orphan) diseases</kwd><kwd>lysosomal storage diseases</kwd><kwd>alpha-mannosidosis</kwd><kwd>clinical manifestations</kwd><kwd>MAN2B1 gene</kwd><kwd>enzyme replacement therapy</kwd><kwd>velmanase alpha</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках финансирования Госзадания «Анализ клинико-генетического полиморфизма инвалидизирующих моногенных заболеваний у детей для прогнозирования их течения и определения молекулярных мишеней для оптимизации лечения» АААА-А18-118051790107-2</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of state Funding «Analysis of clinical and genetic polymorphism of disabled monogenic diseases in children to predict their course and identify molecular targets for optimizing treatment» АААА-А18-118051790107-2</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">Malm D., Nilssen O.
