The earliest signs of the disease were observed as isolated psychoneurological symptoms (mainly as polymorphic extrapyramidal and cerebellar disorders). Neither clinical, nor laboratory, nor sonographic signs of liver pathology were detected. Liver pathology was revealed only during special examination by elastography. The diagnosis was verified by molecular genetic testing (detecting mutations in the <italic>АТР</italic><italic>7В</italic> gene). Challenges of timely recognizing HLD and the modern potential of diagnosing the disease using the laboratory and instrumental techniques are discussed.</p></abstract><trans-abstract xml:lang="ru"><p>Представлено описание случая гепатолентикулярной дегенерации (ГЛД) у пациента 27 лет. Заболевание дебютировало в виде изолированной психоневрологической симптоматики (главным образом, полиморфные экстрапирамидные и мозжечковые расстройства). Каких-либо клинических, лабораторных или ультразвуковых признаков поражения печени обнаружено не было. Выявить патологию печени удалось лишь при специальном исследовании с помощью с помощью эластографии. Диагноз был подтвержден молекулярно-генетическим методом (выявление мутаций в гене <italic>АТР7В</italic>). Обсуждаются сложности своевременного распознавания ГЛД и современные возможности лабораторно-инструментальной диагностики заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hepatolenticular degeneration</kwd><kwd>movement disorders</kwd><kwd>diagnosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гепатолентикулярная дегенерация</kwd><kwd>двигательные расстройства</kwd><kwd>диагностика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Vyalova N.V., Proskokova T.N., Khelimskiy A.M.
