Пациент 17 лет с предположительным диагнозом дистрофия сетчатки. Проведено полное клиническое обследование, включая лабораторные и инструментальные исследования, и секвенирование клинического экзома методом высокопроизводительного секвенирования.Результаты. У пациента выявлены дегенерация фоторецепторной части сетчатки, нормальное моторное и психоречевое развитие, хроническая болезнь почек 2 стадии, мелкие кисты почек и морфологические изменения, характерные для нефронофтиза 1. При молекулярно-генетическом исследовании выявлена делеция всего гена NPHP1 в гомозиготном состоянии, что позволило провести дифференциальную диагностику с заболеваниями со схожими клиническими проявлениями и подтвердило у пациента диагноз синдром Сениора-Локена 1. Анализ сегрегации в семье показал, что у матери выявлена та же делеция в гетерозиготном состоянии. Отец недоступен для исследования.Заключение. Для успешной диагностики наследственных заболеваний со значительной генетической гетерогенностью необходимо применение методов NGS. Для подтверждения делеций и установления точных границ перестройки необходимо полногеномное секвенирование.</p></abstract><trans-abstract xml:lang="en"><p>Aim: to clarify the diagnosis using a thorough study of the clinical picture and molecular genetic diagnostic methods in a complex clinical case of a combination of retinal pathology and kidney disease.Methods. A 17-year-old patient with a presumptive diagnosis of retinal dystrophy had a complete clinical examination, including laboratory and instrumental studies. Сlinical exome sequencing by NGS (next-generation sequencing).Results. The patient was diagnosed with retinal hypoplasia, normal motor and psychomotor development, stage 2 chronic kidney disease, small kidney cysts and morphological changes characteristic of nephronophthisis1. A deletion of the entire NPHP1 gene in a homozygous state was detected, which allowed for differential diagnosis with diseases with similar clinical manifestations and confirmed the diagnosis of Senior-Loken syndrome 1 in the patient. Analysis of segregation revealed that the mother carried the same deletion in a heterozygous state while the father was not available for analysis.Conclusion. For successful diagnostics of hereditary diseases with significant genetic heterogeneity, it is necessary to use NGS methods. To confirm deletions and establish the exact boundaries of the rearrangement, it is necessary to conduct whole-genome sequencing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>NPHP1</kwd><kwd>Senior-Loken 1</kwd><kwd>нефронофтиз 1</kwd><kwd>генетическая гетерогенность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>NPHP1</kwd><kwd>Senior-Loken 1</kwd><kwd>nephronophthisis 1</kwd><kwd>genetic heterogeneity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства образования и науки России для ФГБНУ МГНЦ.</funding-statement><funding-statement xml:lang="en">The work has been funded by the state assignment of the Ministry of Science and Higher Education of the Russian Federation.</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">OMIM. https://omim.org/ (дата обращения 14.03.2025)</mixed-citation><mixed-citation xml:lang="en">OMIM. https://omim.org/ (дата обращения 14.03.2025)</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Antignac C., Arduy C.
