Образцы 2805 пациентов представлены сухими пятнами крови на тест-бланках из фильтровальной бумаги. Биохимическое исследование активности фермента ЛКЛ проводили по протоколу Гамильтона с использованием 4-метилумбеллиферилпальмитата в качестве субстрата и ингибитора ЛКЛ Lalistat-2. Для построения калибровочной кривой использовали значения серийных разведений 4-метилумбеллиферона. Изменения флуоресценции в лунках регистрировали при волне поглощения 355 нм и излучения 460 нм. Для проведения генетического исследования из сухих пятен крови пациентов со сниженной активностью фермента ЛКЛ проводили секвенирование гена LIPA (NM_001127605) на приборе Illumina MiSeq («Illumina», США).Результаты. В результате проведенного биохимического скрининга на дефицит ЛКЛ среди пациентов из групп высокого риска было обнаружено 20 пациентов со сниженными значениями активности фермента ЛКЛ. Для 17 пациентов был проведен поиск вариантов в гене LIPA методом секвенирования нового поколения. У 9 пациентов были найдены патогенные генетические варианты, обуславливающие снижение активности ЛКЛ и проявление клинических симптомов. В 100 % обнаруженных случаев генетические нарушения в гене LIPA включали однонуклеотидную замену c.894G&gt;A. Вместе с данным вариантом были обнаружены два ранее не описанных варианта (c.35dup и c.176A&gt;G) в компаунд-гетерозиготном состоянии.Выводы. Разнообразие клинических симптомов и широкий диапазон возраста проявления симптомов (в случае болезни накопления эфиров холестерина) обуславливают ошибки при постановке диагноза. Вариант c.894G&gt;A является наиболее распространенным в мире среди пациентов с подтвержденным диагнозом дефицита ЛКЛ и присутствует во всех подтвержденных случаях данного исследования, что позволяет предположить, что данный вариант является превалирующим среди патогенных вариантов в гене LIPA в российской популяции. Статус патогенности обнаруженных ранее не описанных вариантов (c.35dup и c.176A&gt;G) требует дополнительного исследования.</p></abstract><trans-abstract xml:lang="en"><p>Aim: to study the prevalence of lysosomal acid lipase deficiency (Wolman disease and cholesteryl ester storage disease) among high-risk patients using selective biochemical screening.Material and methods. Samples from 2805 patients are collected as dried blood spots on filter paper test forms. Biochemical study of the lysosomal acid lipase (LAL) enzyme activity was carried out according to Hamilton’s protocol of, using 4-methylumbelliferyl palmitate as a substrate and LAL inhibitor Lalistat-2. Changes in fluorescence in the wells were recorded on Wallac 1420 Multilabel Counter analyzer at absorption wavelength of 355 nm and emission wavelength of 460 nm. Sequencing of the LIPA gene (NM_001127605) was carried out on an Illumina MiSeq device (Illumina, USA) from dried blood spots from patients with reduced LAL enzyme activity to define genetic variations. Results. As a result of biochemical screening for LAL deficiency among patients from high-risk groups, 20 patients with reduced values of LAL enzyme activity were found. For 17 patients, search for mutations in the LIPA gene was carried out using NGS. In 9 patients, pathogenic genetic variants were found that led to decrease in LAL activity and the manifestation of clinical symptoms. In 100 % of detected cases, genetic mutations in the LIPA gene included single nucleotide substitution c.894G&gt;A. Along with this mutation, two previously undescribed mutations (c.35dup and c.176A&gt;G) were discovered in a compound heterozygous state.Conclusions. The variety of clinical symptoms and wide range of ages at which symptoms may begin (in the case of cholesteryl ester storage disease) can lead to errors in diagnosis. The c.894G&gt;A variant is the most common variant worldwide among patients with a confirmed diagnosis of LAL deficiency and was present in all confirmed cases in this study, suggesting that this variant is the predominant mutation in the LIPA gene in Russian population. Pathogenicity status of previously undescribed discovered mutations (c.35dup and c.176A&gt;G) needs to be determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дефицит лизосомной кислой липазы</kwd><kwd>болезнь Вольмана</kwd><kwd>болезнь накопления эфиров холестерина</kwd><kwd>лизосомные болезни накопления</kwd><kwd>NGS</kwd><kwd>ген LIPA</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lysosomal acid lipase deficiency</kwd><kwd>Wolman disease</kwd><kwd>cholesteryl ester storage disease</kwd><kwd>lysosomal storage diseases</kwd><kwd>NGS</kwd><kwd>LIPA gene</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Cтатья подготовлена к публикации в рамках выполнения государственного задания Министерства науки и высшего образования Российской Федерации № 1021062812133-0-3.2.2 «Оптимизация методов предикции, профилактики и лечения “больших акушерских синдромов”, а также стратегии родоразрешения у беременных из групп высокого риска с целью улучшения акушерских и перинатальных исходов».</funding-statement><funding-statement xml:lang="en">The article was prepared for publication within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation No. 1021062812133-0-3.2.2 “Optimization of methods for prediction, prevention and treatment of “major obstetric syndromes”, as well as strategies for delivery in pregnant women from high-risk groups, in order to improve obstetric and perinatal outcomes”.</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">Jones S.A., Valayannopoulos V., Schneider E., Eckert S., Banikazemi M., Bialer M., et al.
