При этом лишь около 1% случаев СГХС диагностируются в России. Целью данного исследования было определение генетического дефекта в семье с СГХС и проведение ДНК-диагностики у родственников пробанда. Исследование проводили на образцах крови, полученных с информированного согласия пациентов. В работе были использованы методы выделения ДНК из замороженной крови, полимеразная цепная реакция и электрофорез в полиакриламидном геле. Впервые в России был идентифицирован патогенный вариант нуклеотидной последовательности c.683_684insCTG CAAGGACAAATCTGACGA гена рецептора липопротеинов низкой плотности (LDLR) и показана его косегрегация в семье с высоким уровнем холестерина крови. Полученные данные позволяют рассматривать инсерцию c.683_684insCTGCAAGGACAAATCTGACGA как вероятную причину СГХС.</p></abstract><trans-abstract xml:lang="en"><p>Familial hypercholesterolemia (FH) is one of the most common monogenic diseases that leads to the early development of atherosclerosis and is characterized by a poor prognosis. However, only about 1% of FH cases are diagnosed in Russia. The aim of this study was to determine the genetic defect in the FH family and conduct DNA diagnostics in the proband relatives. The study was performed on blood samples obtained with the informed consent of the patients. Polymerase chain reaction and polyacrylamide gel electrophoresis were used. We report c.683_684insCTGCAAGGA CAAATCTGACGA pathogenic variant of the low-density lipoprotein receptor (LDLR) gene for the first time in Russia and demonstrate its cosegregation in a family with high blood cholesterol. The c.683_684in sCTGCAAGGACAAATCTGACGA insertion is considered as a probable cause of FH.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>клинический случай</kwd><kwd>патогенный вариант</kwd><kwd>семейная гиперхолестеринемия</kwd><kwd>сердечно-сосудистые заболевания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>case report</kwd><kwd>pathogenic variant</kwd><kwd>familial hypercholesterolemia</kwd><kwd>cardiovascular disease</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">нет</funding-statement><funding-statement xml:lang="en">none</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">Representatives of the Global Familial Hypercholesterolemia Community, Wilemon KA, Patel J, Aguilar-Salinas C, et al.
