Despite our extensive knowledge regarding <italic>IDH</italic> mutations in intracranial tumors, mutations of this gene in spinal cord astrocytomas remain poorly understood. In this study, we report on five cases of identified mutations in the <italic>IDH1</italic> gene in spinal cord astrocytoma cells, two of which are unique, as they have never been previously described in CNS gliomas.</p></abstract><trans-abstract xml:lang="ru"><p>Низкая частота встречаемости глиом спинного мозга (4.3% в структуре первичных и глиальных опухолей центральной нервной системы) и связанные с этим сложности формирования статистически значимых когорт больных существенно замедляют разработку эффективных подходов к терапии опухолей спинного мозга по сравнению с опухолями головного мозга. Несмотря на существенный багаж знаний о мутациях гена <italic>IDH </italic>в интракраниальных опухолях, крайне мало известно о мутациях этого гена в астроцитомах спинного мозга. В настоящем исследовании мы сообщаем о пяти мутациях в гене <italic>IDH1, </italic>выявленных в клетках астроцитомы спинного мозга, две из которых, впервые описанные в глиомах центральной нервной системы, являются уникальными.</p></trans-abstract><kwd-group xml:lang="en"><kwd>IDH1</kwd><kwd>IDH2</kwd><kwd>spinal cord astrocytoma</kwd><kwd>NGS</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>IDH1$, IDH2$ астроцитома спинного мозга</kwd><kwd>NGS</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">РФФИ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Research</institution></institution-wrap></funding-source><award-id>18-29-01042</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Huse J.T., Aldape K.D. // Clin.
