Диагностика СЦА8 затруднена из-за клинической гетерогенности наследственных атаксий и ограничений стандартных методов. Цель работы − оценить эффективность полного секвенирования генома (ПСГ) короткими прочтениями в диагностике СЦА8 и описать клинические случаи. В исследование включены пациенты с подозрением на наследственную атаксию. ПСГ выполнено на платформе DNBSEQ-T7 с последующим биоинформатическим анализом, включая STRipy для детекции экспансий повторов. Выявлены три семьи с патогенными CTG-экспансиями в гене ATXN8OS. Результаты подтверждают литературные данные о вариабельной пенетрантности и влиянии материнской передачи на тяжесть фенотипа. ПСГ продемонстрировало высокую эффективность в диагностике СЦА8, позволяя одновременно анализировать множество локусов.</p></abstract><trans-abstract xml:lang="en"><p>Spinocerebellar ataxia type 8 (SCA8) is a rare autosomal dominant disorder caused by CTG repeat expansions in ATXN8OS/ATXN8 genes. Diagnosis of SCA8 is challenging due to clinical heterogeneity of hereditary ataxias and limitations of traditional methods. The aim of this work was to evaluate the efficacy of WGS for diagnosing SCA8 and to describe clinical cases. Patients with suspected hereditary ataxia were included. WGS was performed on the DNBSEQ-T7 platform, followed by bioinformatic analysis including STRipy for repeat expansion detection. Three families with pathogenic CTG expansions in ATXN8OS were identified. Results align with published data on variable penetrance and the influence of maternal transmission on phenotypic severity. WGS demonstrated high diagnostic efficacy for SCA8, enabling simultaneous analysis of multiple loci.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спиноцеребеллярная атаксия 8-го типа</kwd><kwd>СЦА8</kwd><kwd>ATXN8OS</kwd><kwd>экспансия тринуклеотидных повторов</kwd><kwd>полногеномное секвенирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spinocerebellar ataxia type</kwd><kwd>SCA8</kwd><kwd>ATXN8OS</kwd><kwd>trinucleotide repeat expansion</kwd><kwd>whole-genome sequencing</kwd><kwd>WGS</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания Министерства науки и высшего образования.</funding-statement><funding-statement xml:lang="en">The study was carried out on the state assignment of the Ministry of Science and Higher Education.</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">Cleary J.D., Subramony S.H., Ranum L.P.W.
