Заболевание может проявляться только мозжечковыми нарушениями или их сочетанием с симптомами поражения других структур ЦНС. Современная классификация СЦА основана на этиологическом принципе: форма болезни определяется на основе гена-причины заболевания. На сегодняшний день известно более 30 генов, мутации которых приводят к доминантным атаксиям. Наиболее частым молекулярным дефектом при СЦА является экспансия тринуклеотидных повторов. Для данной группы болезней описана широкая вариабельность клинической симптоматики, в том числе и у больных членов одной родословной, а, с другой стороны, практически все доминантные атаксии имеют большое сходство клинических проявлений. В работе представлены результаты ДНК-диагностики 335 пробандов с направительным диагнозом « спиноцеребеллярная атаксия » и членов их семей с использованием новой медицинской технологии «Система детекции в одной пробирке частых мутаций генов ATXN1, ATXN2, ATXN3 при спиноцеребеллярных атаксиях».</p></abstract><trans-abstract xml:lang="en"><p>Spinocerebellar ataxias (SCAs) are a group of autosomal dominant inherited disorders characterized by progressive cerebellar ataxia and variable findings. SCAs are classified genetically according to a specific mutation or mapped locus, and also based on the clinical data. There are now more than 30 known genes responsible for spinocerebellar ataxia. SCAs are caused by a polyglutamine trinucleotide repeat CAG expansion. The symptoms of SCA are vary in individual patients and even within the same family. The results of the DNA diagnostics 335 probands with Spinocerebellar ataxia and their families, using of the new medical technology «the detection system in one tube, the frequent mutations in ATXN1, ATXN2, ATXN3 genes in spinocerebellar ataxia», are presented in the research.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спиноцеребеллярная атаксия</kwd><kwd>ATXN1</kwd><kwd>ATXN2</kwd><kwd>ATXN3</kwd><kwd>ДНК-диагностика</kwd><kwd>экспансия тринуклеотидных повторов</kwd><kwd>spinocerebellar ataxia</kwd><kwd>ATXN1</kwd><kwd>ATXN2</kwd><kwd>ATXN3</kwd><kwd>DNA diagnostics</kwd><kwd>expansion</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">Иллариошкин С.Н., Руденская Г.Е., Иванова-Смоленская И.А. и др.
