Заболевание обусловлено гетерозиготными мутациями гена FBN1, который кодирует гликопротеин фибриллин-1, являющийся компонентом эластических микрофибрилл соединительной ткани. На основании обследования взрослых больных высказано мнение, что вариабельность клинического симптомокомплекса синдрома Марфана в значительной степени обусловлена нуклеотидными вариантами гена FBN1.Цель исследования. Сравнительный анализ клинических и генетических данных группы детей с молекулярно-генетически подтвержденным синдромом Марфана. Результаты. Обследование 55 детей показало, что клиническая картина синдрома Марфана характеризуется различными симптомокомплексами. Наиболее тяжелая форма болезни с наличием триады кардинальных признаков (дилатация аорты, эктопия хрусталика, скелетные нарушения) диагностирована менее чем в 1/3 случаев. Более чем у 2/3 пациентов обнаружен неполный симптомокомплекс без отдельных кардинальных проявлений. В соответствии с результатами молекулярно-генетического исследования пациенты были разделены на 2 группы: у 31 ребенка были детектированы мутации гена FBN1, ведущие к гаплонедостаточности, или мутации с потерей функции; у 24 детей выявлены мутации гена FBN1, дающие доминант-негативный эффект. Сравнение клинико-генетических данных пациентов этих двух групп показало, что мутации с потерей функции достоверно (p&lt;0,05) ассоциированы с показателем вовлеченности в патологический процесс соединительной ткани, с более ранней манифестацией патологии органа зрения и при этом с отсутствием эктопии хрусталика.Заключение. Требуется продолжение анализа клинико-генетических взаимосвязей для выработки критериев прогноза течения синдрома Марфана и обоснования медицинского наблюдения пациентов.</p></abstract><trans-abstract xml:lang="en"><p>Marfan syndrome is often found in clinical practice, first of all, by pediatricians, cardiologists, orthopedists, ophthalmologists. The disease is caused by heterozygous mutations of the FBN1 gene. This gene encodes the fibrillin-1 glycoprotein, which is a component of elastic microfibrils of connective tissue. Based on the examination of adult patients with Marfan syndrome, it was suggested that the variability of the clinical symptoms is apparently largely due to the nucleotide variants of the FBN1 gene.Purpose. Comparative analysis of clinical and genetic data of a group of children with molecularly and genetically confirmed Marfan syndrome.Results. Examination of 55 children showed that the clinical picture of Marfan syndrome is characterized by various symptom complexes. The most severe form of the disease with the presence of a triad of cardinal signs (aortic dilatation, ectopia lentis, skeletal disorders) was diagnosed in less than 1/3 of cases. In more than 2/3 of patients, individual cardinal manifestations were absent, making the symptom complex incomplete. According to the molecular genetic results, the patients were divided into 2 groups: 31 children had FBN1 gene mutations leading to haploinsufficiency, or loss-of-function (LoF) mutations; 24 children had FBN1 gene mutations with a dominant negative effect. Comparison of clinical and genetic data of patients of these two groups showed that LoF mutations were significantly (p&lt;0.05) associated with the indicator of involvement in the pathological process of connective tissue, with an earlier manifestation of pathology of the visual organ and at the same time with the absence of ectopia lentis.Conclusion. Further analysis of clinical and genetic relationships is required to develop criteria for predicting the course of Marfan syndrome and substantiating medical observation of patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>синдром Марфана</kwd><kwd>клинические симптомокомплексы</kwd><kwd>ген FBN1</kwd><kwd>LoF-мутации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>сhildren</kwd><kwd>Marfan syndrome</kwd><kwd>clinical symptom complexes</kwd><kwd>FBN1 gene</kwd><kwd>LoF mutations</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">Judge D.P., Dietz H.C.
