Консультирование семей со случаями наследственной моторно-сенсорной нейропатии является трудной задачей для врача-генетика. В статье приведены клинические, электрофизиологические и молекулярно-генетические данные обследования большой семьи из Самары с аутосомно-доминантной наследственной моторно-сенсорной нейропатией. Всем членам семьи проведен неврологический осмотр по стандартной методике. Электромиографическое обследование проводилось с использованием 4-канального электромиографа «Нейро-МВП», фирмы «Нейрософт» (Россия). Молекулярно-генетическое исследование проводилось методом прямого автоматического секвенирования целевых генов и экзомного секвенирования на секвенаторе IlluminaNextSeq 500 методом парно-концевого чтения (2 x 75 п.н.) с использование набора IlluminaTruSeq® ExomeKit. Причиной НМСН в описываемой семье является ранее описанный в большой семье из Сардинии патогенный вариант c.2047-1G&gt;A в интроне 24 гена LRSAM1 . На сегодняшний день описано всего лишь 20 семей, причиной болезни в которых являются патогенные варианты гена LRSAM1 . Особенностями проявлений наследственной моторно-сенсорной нейропатии типа 2P с доминантным типом наследования является поздний возраст манифестации (на 4-5 декаде жизни), асимметрия поражения нижних конечностей, мягкие клинические проявления и медленное прогрессирование не приводящее к инвалидизации. Единственным адекватным методом молекулярно-генетической диагностики данной формы болезни является высокопроизводительное секвенирование. Генетическое тестирование, направленное на поиск выявленной в данной семье мутации, является единственным способом определения генетического риска и профилактики рождения больных детей при достижении членами семей больных детородного возраста.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Charcot-Marie-Tooth disease is clinical polymorphic and genetic heterogeneity group of peripheral nervous system disorders. Genetic counseling for CMT-families is a difficult problem for the doctor. Materials and methods. Autosomal dominant CMT-family from Samara was observed by сlinical, electrophysiological and molecular-genetic methods. Genetic research was performed by direct automatic sequencing of target genes and exome-sequencing on the IlluminaNextSeq 500 sequenator by method of pair and trailer reading (2kh75p.o) about use of the IlluminaTruSeq® ExomeKit set. Results. We identified a splice-site LRSAM1 gene mutation (c.2047-1G&gt;A, p.Ala683ProfsX3). Today only 20 families with LRSAM1 mutations are described. The clinical features in this family is the late age of manifestation (on 4-5 decade of life), asymmetry of atrophy, the weak clinical manifestations and the slow. Conclusion. Genetic diagnostics for this CMT should be carried out by the NGS-methods. Genetic testing is the only way to determine the status of family members for the purpose of planning pre-conception prevention.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наследственная моторно-сенсорная нейропатия</kwd><kwd>LRSAM1</kwd><kwd>экзомное секвенирование</kwd><kwd>Charcot-Marie-Tooth disease</kwd><kwd>exome-sequencing</kwd><kwd>LRSAM1</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">Carr AS, Polke JM, Wilson J et al.
