Особый интерес представляет крайне редкий периодонтальный тип, обусловленный вариантами в генах C1R и C1S и характеризующийся, прежде всего, стоматологическими нарушениями, кожными проявлениями и гипермобильностью суставов.</p><p>В работе представлено описание двух семей. В семье Ф. обследованы пробанд — мужчина 35 лет, и его сын 6 лет. У ребёнка отмечались множественные спонтанные гематомы и экхимозы; у отца — претибиальные бляшки, гипермобильность суставов, ранняя потеря постоянных зубов и рецессия дёсен. Полноэкзомное секвенирование выявило ранее не описанный гетерозиготный вариант NM_001733:c.1073G&gt;A (p.Cys358Tyr) в гене C1R.</p><p>В семье Л. пробанд — женщина 44 лет с хроническими артралгиями, гипермобильностью и нестабильностью суставов, частыми инфекционными заболеваниями; у её сына 20 лет аналогичная симптоматика. По результатам секвенирования идентифицирован также ранее не описанный гетерозиготный вариант NM_001733:c.2066A&gt;G (p.Lys689Arg) в гене C1R.</p><p>Представленные наблюдения подчёркивают необходимость раннего генетического тестирования при подозрении на синдром Элерса-Данло и демонстрируют значимость интеграции клинических и молекулярных данных для точной диагностики редких форм заболевания.</p></abstract><trans-abstract xml:lang="en"><p>Ehlers-Danlos syndrome is a group of hereditary connective tissue disorders with pronounced clinical heterogeneity. Of particular interest is an extremely rare periodontal type caused by C1R and C1S gene variants and characterized primarily by dental disorders, skin manifestations, and joint hypermobility.</p><p>This paper describes two families. In family F., the proband, a 35-yearold man, and his 6-year-old son were examined. The child had multiple spontaneous hematomas and ecchymoses. The father had pretibial plaques, joint hypermobility, early loss of permanent teeth, and gingival recession. Whole exome sequencing revealed a previously undescribed </p><p>heterozygous variant NM_001733:c.1073G&gt;A (p.Cys358Tyr) in the C1R gene.</p><p>In family L., the proband, a 44-year-old woman, presented with chronic arthralgia, joint hypermobility and instability, and frequent infectious diseases. Her 20-year-old son has similar symptoms. Sequencing results also identified a previously undescribed heterozygous variant NM_001733:c.2066A&gt;G (p.Lys689Arg) in the C1R gene.</p><p>These observations highlight the need for early genetic testing when Ehlers-Danlos syndrome is suspected and demonstrate the importance of integrating clinical and molecular data for the accurate diagnosis of rare forms of the disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Элерса-Данло</kwd><kwd>периодонтальный тип</kwd><kwd>ген C1R</kwd><kwd>дифференциальная диагностика</kwd><kwd>наследственные дисплазии соединительной ткани</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ehlers-Danlos syndrome</kwd><kwd>periodontal type</kwd><kwd>C1R gene</kwd><kwd>differential diagnosis</kwd><kwd>hereditary connective tissue disorders</kwd><kwd>case report</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">Malfait F, Francomano C, Byers P, et al.
