Заболевание характеризуется акинезией плода, приводящей к множественному врождённому артрогрипозу, спастичностью, задержкой моторного и психоречевого развития. СВВ обусловлен наличием точковых мутаций или протяжённых делеций в гене ZC4H2, расположенном на длинном плече Х-хромосомы (Xq11.2). В настоящее время в мире описаны около 100 случаев СВВ.</p><p>В статье приведено описание клинического случая СВВ у девочки 5 лет. Диагноз подтверждён полноэкзомным секвенированием и валидирован методом прямого автоматического секвенирования по Сэнгеру. Исследование неслучайной инактивации Х-хромосомы выполнено методом количественной флуоресцентной метилчувствительной полимеразной цепной реакции GAAA-повтора CpG-островка промотора гена RP2.</p><p>Основными клиническими симптомами в нашем случае являются тугоподвижность крупных и мелких суставов, эквиноварусная деформация стоп, специфические лицевые дизморфии, спастичность и отсутствие самостоятельной ходьбы. Мы выявили de novo вариант с.22_23delAT (p.Met8fs) в гене ZC4H2 в гетерозиготном состоянии. Выявлена неслучайная инактивация Х-хромосомы (XCI = 96,1%).</p><sec><title>Заключение</title><p>Заключение. Клиническая картина заболевания, характер выявленной мутации и данные литературы указывают на наличие Х-сцепленного доминантного типа наследования СВВ у нашей пациентки. Описанный нами случай относится к группе ZC4H2-ассоциированных редких расстройств.</p></sec><sec><title>Участие авторов</title><p>Участие авторов:Кондакова О.Б. — концепция, написание текста, редактирование текста; Кузенкова Л.М. — концепция, редактирование текста; Лялина А.А. — написание текста, редактирование текста; Нежельская А.А. — написание текста, редактирование текста; Давыдова Ю.И. — оформление демонстрационных материалов, написание текста; Гребенкин Д.И. — оформление демонстрационных материалов, написание текста; Жанин И.С. — написание текста, редактирование текста; Алексеева Е.А. — проведение лабораторной молекулярно-генетической диагностики, редактирование текста; Канивец И.В. — проведение лабораторной молекулярно-генетической диагностики, редактирование текста; Пушков А.А. — написание текста, редактирование текста. Все соавторы — утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи.</p></sec><sec><title>Финансирование</title><p>Финансирование.

It is characterized by fetal akinesia, which results in congenital multiplex arthrogryposis, spasticity, and development delay. WWS is caused by the point mutations or extended deletions in the ZC4H2 gene, located on the long arm of the X chromosome (Xq11.2). Currently, about 100 cases have been described.</p><p>We present the case of WWS 5-year girl. DNA diagnostic was performed using full exome sequencing and confirmed by Sanger sequencing. Determination of non-random X-chromosome inactivation was performed by methyl-sensitive PCR of GAAA-repeat RP2 gene. </p><p>The main clinical symptoms in our case are stiffness of large and small joints, specific facial phenotype, spasticity and lack of independent walking. We revealed  heterozygous mutation с.22_23delAT (p.Met8fs) in ZC4H2 gene. Non-random inactivation of the X chromosome was detected (XCI = 96.1%).</p><sec><title>Conclusions</title><p>Conclusions. Clinical symptoms of the disease, the nature of the detected mutation and the literature data indicate to the presence of an X-linked dominant pattern of inheritance of WWS in our patient. We described the case referred to the group of ZC4H2-associated rare disorders.</p></sec><sec><title>Contribution</title><p>Contribution:Kondakova O.B. — concept, writing text, editing text;Kuzenkova L.M. — concept, editing text;Lyalina A.A. — writing text; editing text;Nezhelskaya A.A. — writing text; editing text;Davydova Yu.I. — design of demonstrating materials, writing text;Grebenkin D.I. — design of demonstrating materials, writing text;Zhanin I.S. — writing text, editing text;Alekseeva E.A. — conducting laboratory molecular genetic diagnostics, editing text;Kanivets I.V. — conducting laboratory molecular genetic diagnostics, editing text;Pushkov A.A. — writing text, editing text.All co-authors are responsible for the integrity of all parts of the manuscript and approval of its final version.</p></sec><sec><title>Acknowledgements</title><p>Acknowledgements.
