В основе развития патологии лежат варианты в гене NPHP1 (гомозиготные или компаундгетерозиготные), ответственном за структуру и функционирование белка нефроцистина-1 в первичной ресничке. Средний возраст начала терминальной стадии хронической почечной недостаточности при ювенильной форме нефронофтиза 13 лет. Пациенты с нефронофтизом редко обращают внимание на первые характерные клинические проявления заболевания, такие как полиурия и полидипсия, гипостенурия, анемия, что приводит к поздней диагностике заболевания на стадии хронической почечной недостаточности. В статье представлено клиническое наблюдение пациентки 14 лет с манифестацией нефронофтиза 1-го типа с полиурии и полидипсии, гипостенурии. Данное наблюдение демонстрирует начальные проявления и прогрессирование хронической болезни почек у пробанда 14 лет с ювенильным нефронофтизом 1-го типа вследствие мутации гена NPHP1 (хроническая болезнь почек С3Б).</p></abstract><trans-abstract xml:lang="en"><p>Nephronophthisis type 1, juvenile (OMIM 256100) is a rare ciliopathy with an autosomal recessive type of inheritance, which is the most common genetic cause of terminal chronic renal failure in children and young adults. The development of this pathology is caused by mutations in the NPHP1 gene (homozygous or compound heterozygous), responsible for the structure and function of the nephrocystin-1 protein in the primary cilium. The average age of onset of end-stage kidney disease in the juvenile form of nephronophthisis is 13 years. Patients with nephronophthisis rarely pay attention to the first characteristic clinical manifestations of the disease, such as polyuria and polydipsia, hyposthenuria, anemia, which leads to late diagnosis of the disease at the stage of chronic renal failure. The article presents a clinical observation of a 14-year-old female patient with manifestation of nephronophthisis type 1 with polyuria and polydipsia, hyposthenuria. Our observation demonstrates the initial manifestations and progression of chronic kidney disease (chronic kidney disease stage 3B) in a 14-year-old proband with juvenile nephronophthisis type 1 due to a mutation in the NPHP1 gene.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>нефронофтиз</kwd><kwd>хроническая почечная недостаточность</kwd><kwd>цилиопатия</kwd><kwd>нефроцистин</kwd><kwd>кисты почек</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>nephronophthisis</kwd><kwd>chronic renal failure</kwd><kwd>ciliopathy</kwd><kwd>nephrocystin</kwd><kwd>kidney cysts</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">Srivastava S., Sayer J.A.
