Полиморфизм клинических проявлений в группе НДМ обусловливает необходимость дифференциальной диагностики хлорных и натриевых миотоний путем молекулярно-генетического анализа. Целью данной работы является описание спектра мутаций гена SCN4A у пациентов из РФ с натриевыми миотониями. У 13 (54%) пациентов выявлены мутации в гене SCN4A . Пять из выявленных мутаций не описаны в литературе: c.205G&gt;A (p.Gly69Arg), c.638G&gt;A (p.Gly213Asp), c.2003T&gt;C (p.Leu668Pro), c.2017C&gt;G (p.Leu673Val), c.4137G&gt;C (p.Gln1379His). Мутации выявлены у пациентов с диагнозами: миотония Томсена (n = 4), парамиотония Эйленбурга (n = 3), врожденная миотония (n = 2), гиперкалиемическийпаралич (n = 2), гипокалиемический паралич (n = 2). Спектр выявленных в ходе работы мутаций представлен миссенс-заменами, что соответствует данным литературы. Экзоны 12, 13 и 22 гена SCN4A можно считать «горячими», так как мутации в них обусловливают 77% случаев «натриевых» миотоний. Пациентам с диагнозом врожденная миотония и миотоноия Томсена целесообразно проводить молекулярно-генетический анализ гена SCN4A при отсутствии патогенных вариантов в гене CLCN1 .</p></abstract><trans-abstract xml:lang="en"><p>Nondystrophic myotonias are a group of muscle channelopathies. Mutations of CLCN1 and SCN4A genes cause the dysfunction of chloric and sodium ion channels. There are chloric channel myotonias (Thomsen’s and Becker’s types) and sodium channel myotonias (paramyotonia of Eulenburg, HyperkalemicPeriodic paralysis with myotonia, Potassium-aggravated myotonia, Myotonia fluctuans). Patients need in molecular-genetic testing for a right diagnose because some forms of nondystrophic myotonias are very similar. The aim of this work is to describe the spectrum of SCN4A mutations in Russian patients with sodium channel myotonias. The SCN4A mutations were revealed in 13 patients (54%). Five of these mutations were novel: c.205G&gt;A (p.Gly69Arg), c.638G&gt;A (p.Gly213Asp), c.2003T&gt;C (p.Leu668Pro), c.2017C&gt;G (p.Leu673Val), c.4137G&gt;C (p.Gln1379His). All mutations were missense. Mutations in the exons 12, 13 и 22 of SCN4A gene account for 77% causes of sodium channel myotonias. The SCN4A mutations were found in patients with Thomsen’s myotonia (n = 4), paramyotonia of Eulenburg (n = 3), myotonia congenita (n = 2), Hyperkalemic Periodic paralysis (n = 2), Hypokalemic Periodic paralysis (n = 2). It is expediently to make molecular genetic analysis of SCN4A gene for patients with Thomsen’s myotonia and myotonia congenita.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Nondystrophic myotonias</kwd><kwd>paramyotonia of Eulenberg</kwd><kwd>Hyperkalemic Periodic paralysis</kwd><kwd>Hypokalemic paralysis</kwd><kwd>Tomsen’s myotonia</kwd><kwd>SCN4A gene</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">Иванова ЕА, Дадали ЕЛ, Федотов ВП, и др.
