Своевременная диагностика СГХС позволяет проводить профилактику сосудистой патологии. Представлено клиническое наблюдение по выявлению делеции семи нуклеотидов c.925_931del в гене LDLR в семье из Петрозаводска; эта делеция ассоциирована с высоким уровнем общего холестерина плазмы крови и холестерина липопротеинов низкой плотности. Второй вариант нуклеотидной последовательности гена LDLR c.58G&gt;A, обнаруженный в той же семье, не сегрегировал с гиперхолестеринемией. Обнаруженная делеция является причиной СГХС, а проведенный каскадный анализ позволил установить диагноз СГХС у сестры, племянника, дочки и внучки пробанда и исключить этот диагноз у внука.</p></abstract><trans-abstract xml:lang="en"><p>Familial hypercholesterolemia (FH) is one of the most common monogenic diseases in humans, most often caused by defects in the low-density lipoprotein receptor (LDLR) gene. Early diagnosis of FH makes it possible to prevent cardiovascular diseases. We present a case of the detection of a seven-nucleotide deletion c.925_931del in the LDLR gene in a family from Petrozavodsk. This deletion is associated with high levels of total plasma cholesterol and low-density lipoprotein cholesterol. The second variant of the nucleotide sequence of the LDLR gene c.58G&gt;A, detected in the same family, did not segregate with hypercholesterolemia. The detected deletion is the cause of FH, and the conducted cascade analysis made it possible to establish a diagnosis of FH in the sister, nephew, daughter and granddaughter of the proband and to rule out this diagnosis in the grandson.</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 diseases</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнялось в рамках государственного задания Министерства науки и высшего образования РФ: НИР № FGWG-2022-0009</funding-statement><funding-statement xml:lang="en">We are grateful to the management of the Institute of Experimental Medicine for conducting a molecular genetic study at the institute</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">Meshkov AN, Ershova AI, Kiseleva AV, et al.
