Дилатационный фенотип кардиомиопатии (ДКМП) представляет собой группу заболеваний миокарда, основными характеристиками которых являются расширение полости левого желудочка и нарушение его сократительной функции. Благодаря значительному прогрессу в области молекулярной генетики в настоящее время идентифицировано свыше 50 генов, обусловливающих развитие первичной формы КМП, причём на долю мутаций гена MYH7 приходится до 50% генетически подтверждённых случаев. Цель исследования — установить клинические и генетические характеристики КМП с дилатационным фенотипом, обусловленной мутациями в гене MYH7, у детей.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В работе проанализированы данные 250 детей с дилатационным фенотипом КМП, обследованных в кардиологическом отделении ФГАУ «НМИЦ здоровья детей» Минздрава России в 2015–2024 гг. Использованы современные методы молекулярно-генетической диагностики и комплексное клинико-инструментальное обследование с оценкой динамики состояния в течение 5 лет.</p></sec><sec><title>Результаты</title><p>Результаты. Изолированная MYH7-обусловленная КМП с дилатационным фенотипом подтверждена у 80 (40,8%) неродственных детей с выявленными каузальными вариантами. Клиническими характеристиками заболевания являются ранний дебют (более 80% случаев на 1-м году жизни), частое сочетание с некомпактным миокардом (85%) и развитие обратного ремоделирования миокарда левого желудочка на фоне лечения. Установлено, что варианты в экзонах 19–23 ассоциированы с тяжёлой митральной недостаточностью, требующей хирургического вмешательства в раннем возрасте. В 3 случаях отмечено редкое сочетание КМП и миопатии.</p></sec><sec><title>Заключение</title><p>Заключение. Исследование подтверждает важную роль вариантов гена MYH7 в развитии КМП у детей. MYH7-обусловленные формы заболевания при своевременно начатой и адекватной медикаментозной терапии характеризуются благоприятным прогнозом, о чём свидетельствует высокая 5-летняя выживаемость (97,4%) пациентов. Проведение молекулярно-генетической диагностики имеет важное значение в верификации диагноза, организации раннего обследования родственников, прогнозировании течения заболевания. Систематизация клинико-генетических характеристик создаёт фундамент для разработки персонализированных подходов к лечению. Междисциплинарный подход к ведению пациентов с КМП и экстракардиальными проявлениями приобретает особое значение.</p><p>Соблюдение этических стандартов.

The dilated cardiomyopathy (DCM) represents a group of myocardial disorders whose primary characteristics are dilation of the left ventricular cavity and impaired systolic function. Thanks to significant progress in the field of molecular genetics, over fifty genes responsible for the primary form of DCM have now been identified, with mutations in the MYH7 gene accounting for up to 50% of all genetically confirmed cases. Objective: to establish the clinical and genetic characteristics of the dilated cardiomyopathy caused by mutations in the MYH7 gene in children.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. This study analyzed data from 250 DCM children examined at the Cardiology department of the National Medical Research Center for Children’s Health of the Ministry of Health from 2015 to 2024. The investigation employed modern molecular genetic diagnostic methods and comprehensive clinical and instrumental examination, with assessment of clinical dynamics over a 5-year period.</p></sec><sec><title>Results</title><p>Results. Isolated MYH7-associated DCM was confirmed in 80 (40,8%) unrelated children with identified causative variants. The clinical characteristics of the disease include early onset (over 80% of cases manifesting within the first year of life), frequent combination with non-compaction of the myocardium (85%), and the development of left ventricular reverse remodeling following treatment.Variants in exons 19–23 were established to be associated with severe mitral regurgitation, requiring surgical intervention at an early age. In 3 cases, a rare combination of cardiomyopathy and myopathy was observed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study confirms the significant role of pathogenic variants in the MYH7 gene in the development of cardiomyopathy in children. MYH7-associated forms of the disease with timely and appropriate drug therapy are characterized by a favorable prognosis, as evidenced by the high 5-year survival rate (97,4%) in patients. Molecular genetic testing is important in verifying the diagnosis, managing an early screening of relatives, and predicting the course of disease. The systematization of clinical and genetic characteristics creates the foundation for the devilment of personalized treatment approaches. A multidisciplinary approach to managing patients with cardiomyopathy and extracardiac manifestations is of particular importance.</p><p>Compliance with ethical standards.
