Туберозный склероз – орфанное системное заболевание с аутосомно–доминантным типом наследования, характеризующееся образованием опухолевидных доброкачественных узловых гамартом с поражением кожи, нервной системы, сетчатки глаза, почек, сердца, легких. У 50–70 % детей и подростков с туберозным склерозом диагностируют почечный фенотип, чаще в виде ангиомиолипом и кист паренхимы почек. Наличие поражения почек осложняет течение и прогноз туберозного склероза в связи с риском развития острого повреждения почек и прогрессированием хронической болезни почек.ЦЕЛЬ: описать семейный туберозный склероз (ORPHA:805) вследствие патогенной мутации гена TSC2 с аутосомно-доминантным типом наследования.ПАЦИЕНТЫ И МЕТОДЫ. Представлены особенности клинического фенотипа и генотипа туберозного склероза у пробанда – девочки 16 лет и ее отца – мужчины 45 лет. Применены генеалогический, клинический, визуализирующий, функциональный, молекулярногенетический методы исследования. Молекулярно-генетический метод исследования выполнен в лаборатории молекулярной патологии медико-генетического центра ООО «Геномед».РЕЗУЛЬТАТЫ. Пациентке 16 лет в раннем возрасте диагностирован туберозный склероз при наличии 2 больших критериев (1. рабдомиома сердца пренатально и при рождении, 2. кортикальные туберы лобной и теменной области, очаги обызвествления в мозжечке, уменьшение гиппокампа проявляющиеся задержкой речевого развития и эпилепсией с атоническими и генерализованными тоникоклоническими приступами в грудном и раннем возрасте). Проявления почечного фенотипа (увеличение объема почек и паренхиматозные кисты) выявлены в возрасте 6 лет, ангиомиолипомы печени отмечены в 8 лет, почек – в 16 лет. При молекулярно-генетическом исследовании у пробанда идентифицирована патогенная мутация гена TSC2 (c.1052A&gt;G, p.Lys351Arg). Почечная функция у пробанда в возрасте 16 лет соответствует 2 стадии хронической болезни почек (СКФ 84 мл/мин/1,73 м2). Аналогичная мутация выявлена у отца пробанда, имеющего нормальную скорость клубочковой фильтрации (134 мл/мин/1,73 м2), одиночную кисту почки, туберозный склероз диагностирован в возрасте 45 лет по 2 большим критериям (3 околоногтевые фибры и 3 гипопигментированные пятна более 5 мм на коже).ЗАКЛЮЧЕНИЕ. Описаны особенности клинического фенотипа семейного орфанного туберозного склероза вследствие ранее не описанного варианта мутации гена TSC2 у пробанда – девочки и отца.</p></abstract><trans-abstract xml:lang="en"><p>BACKGROUND. Tuberous sclerosis is an orphan systemic disease with an autosomal dominant inheritance characterized by the formation of tumor–like benign nodular hamartomas with lesions of the skin, nervous system, retina, kidneys, heart, and lungs. In 50–70 % of children and adolescents with tuberous sclerosis, the renal phenotype is more often diagnosed in the form of angiomyelitis and kidney parenchymal cysts. The presence of kidney damage complicates the course and prognosis of tuberous sclerosis due to the risk of acute kidney injury and the progression of chronic kidney disease.OBJECTIVE: To describe familial tuberous sclerosis (ORPHA:805) due to a pathogenic mutation of the TSC2 gene with an autosomal dominant type of inheritance.PATIENTS AND METHODS. The features of the clinical phenotype and genotype of tuberous sclerosis in a 16–year-old proband girl and her 45-year-old male father are described. Genealogical, clinical, imaging, functional, and molecular genetic research methods have been applied. The molecular genetic research method was performed in the laboratory of molecular pathology of the medical and genetic center of Genomed.RESULTS. A 16-year–old patient was diagnosed with tuberous sclerosis at an early age in the presence of 2 major criteria (1. rhabdomyoma of the heart prenatally and at birth, 2. cortical tubers of the frontal and parietal regions, foci of calcification in the cerebellum, decreased hypocampus manifested by delayed speech development and epilepsy with atonic and generalized tonic-clonic seizures in infancy and early age). Manifestations of the renal phenotype (increased kidney volume and parenchymal cysts) They were detected at the age of 6 years, liver angiomyolipomas were noted at the age of 8, and kidneys at the age of 16. A molecular genetic study identified a pathogenic mutation of the TSC2 gene in the proband (c.1052AG, p.Lys351Arg). The renal function in proband at the age of 16 years corresponds to stage 2 of chronic kidney disease (GFR 84ml/min/1.73 m2). A similar mutation was detected in Proband's father, who has a normal glomerular filtration rate (134ml/min/1.73 m2), a single kidney cyst, tuberous sclerosis was diagnosed at the age of 45 according to 2 major criteria (3 periarticular fibroids and 3 hypopigmented spots over 5 mm on the skin).СONCLUSION. The features of the clinical phenotype of familial orphan tuberous sclerosis due to a previously undescribed mutation of the TSC2 gene in a proband girl and father are described.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>туберозный склероз</kwd><kwd>дети</kwd><kwd>взрослые</kwd><kwd>ген TSC2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tuberous sclerosis</kwd><kwd>children</kwd><kwd>adults</kwd><kwd>TSC2 gene</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">Caliment A, Van Reeth O, Hougardy Ch et al.
