Синдром Элерса-Данло (СЭД) представляет собой наследственное заболевание соединительной ткани, чаще всего ассоциированное с мутациями в генах коллагена V типа, однако данные о спектре наследственных нарушений у пациентов из России фрагментарны.</p></sec><sec><title>Цель</title><p>Цель: поиск мутаций в генах коллагена 5 типа у пациентов с СЭД из Республики Башкортостан.</p></sec><sec><title>Методы</title><p>Методы. Использованы образцы ДНК 43 пациентов (средний возраст 28,6±7,44 лет) из 37 семей с СЭД, проживающих на территории Республики Башкортостан.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено пять изменений нуклеотидной последовательности в гене COL5A1 и три – в гене COL5A2. Обнаружены патогенные варианты c.212delС, (p.Pro71ArgfsTer33) и c.4135C&gt;T (p.Pro1379Ser) в гене COL5A1, ранее не описанные в литературе.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Ehlers–Danlos syndrome (EDS) is an inherited connective tissue disorder most commonly associated with mutations in type V collagen genes. However, data on the spectrum of hereditary variants among patients from Russia remain fragmentary.</p></sec><sec><title>Aim</title><p>Aim: to identify mutations in type V collagen genes in patients with Ehlers–Danlos syndrome from the Republic of Bashkortostan.</p></sec><sec><title>Methods</title><p>Methods. DNA samples from 43 patients (mean age 28.6 ± 7.44 years) representing 37 families with Ehlers–Danlos syndrome residing in the Republic of Bashkortostan were analyzed.</p></sec><sec><title>Results</title><p>Results. Five nucleotide sequence alterations were detected in the COL5A1 gene and three in the COL5A2 gene. Pathogenic variants c.212delC (p.Pro71ArgfsTer33) and c.4135C&gt;T (p.Pro1379Ser) in COL5A1 were identified, which have not been previously described in the literature.</p></sec><sec><title>Conclusions</title><p>Conclusions. Mutations were identified in eight unrelated families with EDS from the Republic of Bashkortostan. In total, five nucleotide sequence alterations were found in the COL5A1 gene and three in the COL5A2 gene.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Элерса-Данло</kwd><kwd>секвенирование</kwd><kwd>мутации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ehlers-Danlo syndrome</kwd><kwd>sequencing</kwd><kwd>mutations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № №25-75-00057 (https://rscf.ru/project/25-75-00057)</funding-statement><funding-statement xml:lang="en">This study was supported by the Russian Science Foundation, grant No. 25-75-00057 (https://rscf.ru/project/25-75-00057)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Malfait F., Castori M., Francomano C.A., et al.
