При проведении таргетного панельного секвенирования был выявлен описанный ранее патогенный вариант c.272A&gt;C (p.D91A, rs80265967) в 4-м экзоне гена SOD1. Варианты в данном гене являются частой причиной развития наследственных форм бокового амиотрофического склероза (БАС, MIM #105400). Сочетание клинической картины БАС с мозжечковой атаксией является крайне редким феноменом, а случаев обнаружения данной мутации у пациентов с мозжечковой атаксией ранее описано не было. Представленное клиническое наблюдение и данные литературы расширяют представления о генетическом и фенотипическом «перекресте» наследственных атаксий и болезней двигательного нейрона. В настоящее время проводится активная разработка препаратов для генной терапии SOD1- БАС, в том числе с использованием антисмысловых олигонуклеотидов, направленных на подавление экспрессии гена SOD1. В связи этим необходимо включать исследование гена SOD1 в алгоритмы диагностики наследственных мозжечковых атаксий при наличии характерного клинического фенотипа.</p></abstract><trans-abstract xml:lang="en"><p>We report a clinical case of the patient with a rare phenotype presented by progressive cerebellar ataxia in combination with upper and lower motor neuron involvement. Target panel sequencing revealed the previously described pathogenic mutation c.272A&gt;C (p.D91A, rs80265967) in the 4th exon of the SOD1 gene. Mutations in this gene are a common cause of the hereditary forms of amyotrophic lateral sclerosis (ALS, MIM #105400). The combination of ALS with cerebellar ataxia is an extremely rare, and cases of association of this mutation with cerebellar ataxia have not been previously described. The presented clinical observation and literature data expand the understanding of the genetic and phenotypic “overlap” of hereditary ataxias and motor neuron diseases. The development of drugs for SOD1-ALS gene therapy, including the use of antisense oligonucleotides aimed at suppressing SOD1 gene expression, is currently underway. In this regard, it is necessary to include the study of the SOD1 gene in the algorithms for diagnosing hereditary cerebellar ataxia in the presence of a characteristic clinical phenotype.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спиноцеребеллярная атаксия</kwd><kwd>боковой амиотрофический склероз</kwd><kwd>болезнь двигательного нейрона</kwd><kwd>ген SOD1</kwd><kwd>клиническая картина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spinocerebellar ataxia</kwd><kwd>amyotrophic lateral sclerosis</kwd><kwd>motor neuron disease</kwd><kwd>SOD1 gene</kwd><kwd>clinical presentation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России для ФГБНУ «Научный центр неврологии»</funding-statement><funding-statement xml:lang="en">The research was carried out within the state assignment of 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">Nuzhnyi, E.P., Abramycheva, N.Y., Safonov, D.G. et al.
