Клинические проявления заболевания обусловлены накоплением специфических цитоплазматических «амилоидных включений», состоящих из полиглюкозанов (аномально разветвленная молекула гликогена). Полиглюкозаны, или тельца Лафора, обнаруживают в головном мозге, гепатоцитах печени, скелетных и сердечной мышцах, в протоках потовых желез, коже. Диагноз устанавливается на основании наличия сенсорных зрительных, генерализованных тонико-клонических и миоклонических эпилептических приступов, прогрессирующей деменции и атаксии, обнаружения специфических телец Лафора при биопсии потовых желез, данных генетического тестирования.</p><p>В статье описан клинический случай болезни Лафора, вызванный мутацией в гене EPM2A (лафорин) с дебютом в возрасте 11 лет с фокальных сенсорных зрительных приступов с дальнейшим присоединением генерализованных тонико-клонических и миоклонических приступов, прогрессированием двигательных нарушений в виде атаксии и нарушения походки, поведенческих и когнитивных нарушений. Представленный клинический случай демонстрирует необходимость проведения дополнительных исследований, таких как биопсия, генетическое тестирование для диагностики заболеваний, протекающих с резистентными эпилептическими приступами, прогрессирующими двигательными и когнитивными нарушениями.</p></abstract><trans-abstract xml:lang="en"><p>Lafora disease is a hereditary, autosomal recessive progressive myoclonus epilepsy caused by mutations in the EPM2A (laforin) and EPM2B (malin) genes, with no substantial genotype-phenotype differences between the two. Clinical manifestations of the disease are determined by the accumulation of specific cytoplasmic “amyloid inclusions” consisting of polyglycosans (an abnormally branched glycogen molecule). Polyglycosans, or Lafora bodies, are typically found in the brain, hepatocytes of the liver, skeletal and cardiac muscles, in the ducts of sweat glands, and in the skin. The diagnosis is made following visual, generalized tonic-clonic and myoclonic seizures, progressing dementia, cerebellar ataxia, detection of specific Lafora bodies during sweat gland biopsy and data of genetic testing.</p><p>The article describes a clinical case of Lafora disease in a patient with disease onset at 11 years old caused by the mutation in the EPM2A (laforine) gene with focal sensory visual seizures with subsequent generalized tonic-clonic seizures, progressive motor impairments in the form of ataxia and gait abnormality as well as behavioral and cognitive disorders. The presented clinical case demonstrates the need for additional research, such as biopsy and genetic testing, for diagnosing diseases proceeding with resistant epileptic seizures and progressive motor and cognitive impairments. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>прогрессирующая миоклоническая эпилепсия</kwd><kwd>мутация в генах EPM2A и EPM2B</kwd><kwd>тельца Лафора</kwd></kwd-group><kwd-group xml:lang="en"><kwd>progressive myoclonus epilepsy</kwd><kwd>EPM2A and EPM2B genes mutations</kwd><kwd>Lafora bodies</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">Minassian B.A., Lee J.R., Herbrick J.A. et al.
