Мукополисахаридоз I типа (МПС I) заболевание, известное более 100 лет. Появление новых подходов к терапии МПС I ставит перед врачом необходимость четкого разграничения подтипов заболевания для эффективного и рационального использования методов лечения. Описание клинического случая. Девочка Б. с ранним дебютом МПС I в неонатальном периоде. Симптомы поражения опорно-двигательного аппарата: приведение переднего отдела стоп и дисплазия тазобедренных суставов. При дальнейшем наблюдении в возрасте 6 мес выявлены задержка линейного роста, пупочная грыжа и экссудативный отит. Психомоторное развитие до года — с темповой задержкой. К 1,5 годам огрубление черт лица, что в совокупности с ортопедическими проблемами, экссудативным отитом и наличием пупочной грыжи послужило поводом для диагностики мукополисахаридоза. Диагноз «мукополисахаридоз, тип I» был установлен на основании данных клинической картины, энзимодиагностики — выраженного снижения активности лизосомного фермента альфа-L-идуронидазы (0,26 мкмоль/л/ч; референсные значения от 1,96) и данных молекулярно-генетического обследования — наличия патогенного варианта с.208C&gt;T (Gln70Ter) в экзоне 2 и нуклеотидного варианта неизвестного клинического значения с.1524G&gt;C (p.Glu508Asp) в экзоне 10 гена IDUА в компаунд-гетерозиготном состоянии. При инструментальном обследовании по данным эхокардиографии выявлены особенности строения митрального клапана и минимальная аортальная недостаточность. По данным ультразвукового исследования органов брюшной полости — признаки гепатомегалии, гидрокаликоза, пиелоэктазии справа, размеры почек меньше возрастных норм. Проведена магнитно-резонансная томография органов брюшной полости — картина простых кист почек. Заключение. Особенностью данного клинического случая является сложность дифференциальной диагностики между тяжелой формой МПС I — синдромом Гурлер и более мягкой формой — синдромом Гурлер – Шейе. Наличие у пациентки, по данным молекулярно-генетического обследования, частого патогенного варианта с.208C&gt;T (Gln70Ter) в гене IDUA, ассоциированного с тяжелым течением заболевания, и нуклеотидного варианта с неопределенной клинической значимостью с.1524G&gt;C (p.Glu508Asp) требует дообследования — проведения функционального анализа ранее не описанного варианта для установления его влияния на функцию белка, что поможет более точно установить форму заболевания и спрогнозировать тяжесть его течения. Уникальным для данного случая является сочетание МПС I и поликистоза почек у пробанда.</p></abstract><trans-abstract xml:lang="en"><p>Background. Mucopolysaccharidosis type I (MPS I) is a disease known for over 100 years. Implementation of new management approaches for MPS I requires from doctor to clearly differentiate subtypes of this disease for the effective and rational use of treatment methods. Clinical case description. Girl B. with early MPS I onset during the neonatal period. Symptoms of musculoskeletal system damage were the following: feet adduction and hip joints dysplasia. Further follow-up at the age of 6 months has shown linear growth retardation, umbilical hernia, and exudative otitis. Psychomotor development up to 1 year of age was delayed. Coarse facial features by the age 1.5 years along with orthopedic problems, exudative otitis, and umbilical hernia led to mucopolysaccharidosis diagnosis. The diagnosis of mucopolysaccharidosis type I was established according to clinical findings, enzyme diagnostics (significant decrease in lysosomal enzyme alpha-L-iduronidase activity — 0.26 μmol/l/h; reference values from 1.96), and molecular genetic testing (pathogenic variant c.208C&gt;T (Gln70Ter) in exon 2 and nucleotide variant of unknown clinical value c.1524G&gt;C (p.Glu508Asp) in exon 10 of IDUA gene in compound heterozygous state). Echocardiography has revealed structural changes in the mitral valve and minimal aortic insufficiency. Abdominal ultrasound has revealed signs of hepatomegaly, hydrocalycosis, right-side pyelectasia, kidneys’ sizes lesser than the age norms. Abdominal magnetic resonance imaging has shown simple kidney cysts. Conclusion. The major feature of this clinical case is the complexity of differential diagnosis between the severe form of MPS I, Hurler syndrome, and milder form, Hurler–Scheie syndrome. Molecular genetic testing has revealed the presence of the frequent pathogenic variant c.208C&gt;T (Gln70Ter) in the IDUA gene associated with severe disease course and nucleotide variant c.1524G&gt;C (p.Glu508Asp) with undefined clinical significance, thus, additional examination is necessary. Functional analysis of the novel variant is required to establish its role in protein function. It will help more precisely determine the disease form and predict its severity. Combination of MPS I and polycystic kidney disease in the proband is unique case.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мукополисахаридоз I типа</kwd><kwd>синдром Гурлер</kwd><kwd>синдром Гурлер – Шейе</kwd><kwd>дифференциальная диагностика</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mucopolysaccharidosis type I</kwd><kwd>Hurler syndrome</kwd><kwd>Hurler–Scheie syndrome</kwd><kwd>differential diagnosis</kwd><kwd>clinical case</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Отсутствует.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>Not declared.</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">Mucopolysaccharidosis Type I: Search results in PubMed Central (PMC).
