Rare contiguous COL4A5–COL4A6 alterations cause AS with diffuse leiomyomatosis (AS-DL).</p><sec><title>Case report</title><p>Case report. A 16-year-old male had mild proteinuria, hematuria, hearing loss and myopia since childhood. Estimated glomerular filtration rate was 82.8 mL/min/1.73 m². Kidney biopsy showed segmental mesangial sclerosis; immunofluorescence was negative. Electron microscopy demonstrated diffuse glomerular basement membrane thinning and podocyte foot-process effacement. Two deceased brothers had end stage kidney disease; the mother had hematuria, uterine myoma, and a benign bladder tumor. A diagnosis of X-linked AS was established according to the Flinter criteria and nephroprotective treatment was initiated. Since 2024, the patient had complained of epigastric symptoms. An endoscopy revealed a 2-cm gastric submucosal lesion. A whole-exome sequencing identified a hemizygous missense variant in COL4A5 and a COL4A6 exon 1–2 deletion, confirming AS-DL.</p></sec><sec><title>Discussion</title><p>Discussion. This case demonstrates the co-occurrence of AS-DL and shows that early pedigree assessment, combined with integrated clinicopathologic-genetic evaluation in a multidisciplinary framework, enables a timely diagnosis of atypical familial AS-DL and improves clinical management.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Синдром Альпорта (СА) – наследственная нефропатия, обусловленная мутациями в генах COL4A3, COL4A4 и COL4A5.

У 16-летнего пациента с детства отмечались умеренная протеинурия, гематурия, снижение слуха и миопия. Расчетная СКФ – 82,8 мл/мин/1,73 м2. Биопсия почки: сегментарный мезангиальный склероз; иммунная флюоресценция отрицательна. Электронная микроскопия: диффузное истончение гломерулярной базальной мембраны и слияние ножек подоцитов. Двое братьев с терминальной почечной недостаточностью умерли в подростковом возрасте; у матери – гематурия, миома матки и доброкачественная опухоль мочевого пузыря. Диагноз Х-сцепленного СА установлен по критериям Флинтера; начата нефропротективная терапия. С 2024 года появились эпигастральные жалобы; эндоскопия выявила подслизистое образование желудка размером 2 см. Полногеномное секвенирование обнаружило гемизиготный миссенс-вариант в COL4A5 и делецию экзонов 1–2 COL4A6, что подтвердило СА-ДЛ.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Представленный случай демонстрирует сочетание СА с ДЛ и показывает, что ранний семейный скрининг в сочетании с мультидисциплинарным клиническим, гистопатологическим и генетическим обследованием обеспечивает своевременную диагностику атипичных семейных форм СА-ДЛ и улучшает тактику ведения пациентов.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лейомиома</kwd><kwd>нефритический синдром</kwd><kwd>опухоли матки</kwd><kwd>Х-сцепленные генетические заболевания</kwd><kwd>опухоли гладкой мускулатуры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>leiomyoma</kwd><kwd>nephritic syndrome</kwd><kwd>uterine neoplasms</kwd><kwd>X-linked genetic diseases</kwd><kwd>smooth muscle tumors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки (собственные ресурсы).</funding-statement><funding-statement xml:lang="en">The study had no sponsorship (own resources).</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">Gregorio V., Caparali E.B., Shojaei A., et al.
