Альфа-маннозидоз — это ультраредкое аутосомно-рецессивное заболевание из группы лизосомных болезней накопления, вызванное мутацией в гене MAN2B1. Патогенные нуклеотидные замены и структурные перестройки в данном гене приводят к дефициту фермента кислой альфа-маннозидазы, участвующей в деградации олигосахаридов. Болезнь характеризуется мультисистемным поражением и хроническим прогрессирующим течением.</p><p>Описание клинического случая. Клинический случай привлек внимание поздней диагностикой заболевания у мальчика, проживающего в мегаполисе. У ребенка имеются классические клинические проявления заболевания: характерный фенотип, деформация позвоночника, задержка моторного и речевого развития, снижение слуха, гепатомегалия, спленомегалия, пупочная и паховая грыжи. Несмотря на задержку речевого развития и частые повторные отиты, пациент до 4,5 лет не был направлен к сурдологу для обследования. Интересным фактом представляется наличие у ребенка врожденной катаракты, в связи с чем он был оперирован 2 раза.</p></sec><sec><title>Заключение</title><p>Заключение. Врожденная катаракта является одним из ранних признаков данного заболевания. Из 8 пациентов с альфа-маннозидозом, наблюдающихся в нашем учреждении, трое имели врожденную катаракту. Вероятно, такие больные должны быть направлены к генетику для раннего исключения альфа-маннозидоза. Поздняя диагностика, прогрессирующий характер заболевания привели к ранней инвалидизации пациента. В связи с появлением ферментозаместительной терапии крайне важным является своевременное выявление этих пациентов с целью улучшения качества их жизни и увеличения выживаемости.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Alfa-mannosidosis is ultra-rare autosomal recessive lysosomal storage disease caused by the mutation in the MAN2B1 gene. Pathogenic nucleotide variants and structural changes in this gene lead to acid alpha-mannosidase deficiency, this enzyme is involved in oligosaccharides degradation. This disease is characterized by multisystem involvement and chronic progressive course.</p><p>Clinical case description. The clinical case attracted our attention due to the late disease diagnosis in a boy living in a metropolis. The child has classic clinical manifestations of the disease: typical phenotype, spinal deformity, developmental speech and motor delays, hearing loss, hepatomegaly, splenomegaly, umbilical and inguinal hernias. Despite developmental speech delay and frequent recurrent otitis, the patient has not been referred to surdologist examination until the age of 4.5 years. Intriguing fact is the presence of congenital cataract that was the reason for surgery twice.</p></sec><sec><title>Conclusion</title><p>Conclusion. Congenital cataract is one of the early manifestation of this disease. 3 out of 8 patients with alfa-mannosidosis observed in our centre had congenital cataract. We assume that such patients should be referred to genetics for the early exclusion of alpha-mannosidosis. Late diagnosis and progressive course of the disease led to early disability of the patient. Nowadays, as enzyme replacement therapy is available, it is crucial to identify these patients timely in order to improve their quality of life and increase survivability.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>альфа-маннозидоз</kwd><kwd>клинический случай</kwd><kwd>тугоухость</kwd><kwd>деформация позвоночника</kwd><kwd>атаксия</kwd><kwd>врожденная катаракта</kwd><kwd>задержка речевого развития</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alfa-mannosidosis</kwd><kwd>clinical case</kwd><kwd>hearing loss</kwd><kwd>spinal deformity</kwd><kwd>ataxia</kwd><kwd>congenital cataract</kwd><kwd>developmental speech delay</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Отсутствует</funding-statement><funding-statement xml:lang="en">Not specified</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">Ockerman PA, Lund MD.
