К настоящему времени известен ряд наследственных заболеваний, за возникновение которых ответственны гетерозиготные мутации в гене DYNC1H1. Считается, что формирование разнообразных клинических проявлений обусловлено различным влиянием мутаций на функцию его белкового продукта. Результаты. Представлены клинико-генетические характеристики российских больных с двумя вариантами заболеваний - спинальной мышечной атрофии с преимущественным поражением нижних конечностей (СМАНК) и умственной отсталости тип 13 (УО13) в сочетании с пороками развития головного мозга и эпилепсией - обусловленных вновь выявленными мутациями в гене DYNC1H1. Заключение. Полученные результаты подтверждают гипотезу о том, что мутации, нарушающие аминокислотную последовательность хвостового домена динеина приводят к возникновению СМАНК, а моторного домена – к УО13. Выраженная генетическая гетерогенность УО и СМАНК, отсутствие специфических клинических маркеров и мажорных мутаций в гене DYNC1H1, а также в других генах, ответственных за возникновение этих групп заболеваний обуславливает необходимость в качестве основного метода их диагностики использовать секвенирование экзома или генома с анализом ДНК больного и его родителей.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. To date, DYNC1H1 gene mutations are known for large number of hereditary diseases. It is believed that different mutations have variable effects to protein function and, accordingly, to various clinical manifestations. Results. There are a clinical and genetic characteristics of two Russian patients with two types of diseases: spinal muscular atrophy with predominant lesion of the lower extremities (SMALED) and non-syndromic mental retardation type 13 (MR13) in combination with a brain malformations and epilepsy due to newly identified mutations in the DYNC1H1 gene. Conclusion There is some evidence in support of the hypothesis that the amino acid sequence changing in the tail domain of dynein lead to the appearance of SMALED, and in the motor domain lead to MR13. Exome or genome sequencing are required as the main method for their diagnosis due to the high genetic heterogeneity of non-syndromic MR and SMALED, the lack of specific clinical markers and hotspot mutations in the DYNC1H1 gene.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спинальная мышечная атрофия с преимущественным поражением ног</kwd><kwd>умственная отсталость 13-го типа</kwd><kwd>динеин</kwd><kwd>секвенирование экзома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spinal muscular atrophy with predominant lesion of the legs</kwd><kwd>mental retardation type 13</kwd><kwd>dynein</kwd><kwd>exome sequencing</kwd><kwd>SMALED</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study had no sponsorship.</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">Van der Vleuten A.J., van Ravenswaaij-Arts C.M., Frijns C.J. et al.
