Ген TUBB4A кодирует мозгоспецифический белок тубулин бета-4А, входящий в состав стенок микротрубочек, которые представляют собой основной компонент цитоскелета. Мутации в гене TUBB4A приводят к снижению стабильности микротрубочек, нарушению их функции поддержания клеточной структуры и транспортной функции. Гипомиелинизирующая лейкодистрофия, тип 6, характеризуется манифестацией в раннем детском возрасте задержкой моторного развития, неустойчивостью походки с нарастанием экстрапирамидных расстройств. Авторы обосновывают необходимость мультидисциплинарного подхода к диагностированию и ведению пациентов данной категории и подчеркивают, что ключевым для диагностики гипомиелинизирующих лейкодистрофий являются современные молекулярно-генетические методы, в частности секвенирование нового поколения.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of long-term dynamics of the clinical and radiological picture of a child with a rare neurodegenerative disease — hypomyelinating leukodystrophy, type 6 (hypomyelinating leukodystrophy with atrophy of the basal ganglia and cerebellum) caused by a de novo mutation in the TUBB4A gene. The TUBB4A gene encodes a brain-specific protein — tubulin beta-4A, being a part of the walls of microtubules, which are the main component of the cytoskeleton. Mutations of the TUBB4A gene decrease the stability of microtubules, violate their functions of maintaining the cellular structure and transportation. Hypomyelinizing leukodystrophy, type 6, is manifested by a delayed motor development, instability of the gait with an increase in extrapyramidal disorders in young children. The authors substantiate the need for a multidisciplinary approach to the diagnosis and management of patients of this category and emphasize that the modern molecular genetic methods, in particular sequencing of a new generation are the key methods in the diagnosis of hypomyelinizing leukodystrophies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>гипомиелинизирующая лейкодистрофия</kwd><kwd>атрофия базальных ганглиев и мозжечка</kwd><kwd>тубулин бета-4А</kwd><kwd>TUBB4A</kwd><kwd>массовое параллельное секвенирование</kwd><kwd>медико-генетическое консультирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>hypomyelinizing leukodystrophy</kwd><kwd>atrophy of the basal ganglia and cerebellum</kwd><kwd>tubulin beta-4A</kwd><kwd>TUBB4A</kwd><kwd>mass parallel sequencing</kwd><kwd>genetic counseling</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">Михайлова С.В., Захарова Е.Ю., Петрухин А.С.
