В данной работе представлена биохимическая и молекулярно-генетическая характеристика 16 пациентов с ПА, выявленных в Российской Федерации. У большинства обследованных пациентов первые симптомы проявились в первые месяцы жизни, наиболее частые из них: нарушения вскармливания, судороги, мышечная гипотония, угнетение сознания. При биохимическом исследовании (ГХ-МС и МС/МС) у пациентов было выявлено повышение концентрации 3-гидроксипропионой кислоты, метилцитрата, пропионилглицина, C3, глицина, которые являются патогномоничными маркерами этой патологии. В результате молекулярно-генетического анализа в генах PCCA и PCCB было выявлено 6 неописанных ранее вариантов нуклеотидной последовательности (4 варианта в гене PCCA, 2 - в гене PCCB), один из которых (PCCB: c.655-2A&gt;G) имеет высокую частоту (17,2%, 5/29 мутантных аллелей генов PCCA и PCCB) в исследуемой выборке. Локализация миссенс-вариантов и их влияние на структуру белка были продемонстрированы на 3D-модели фермента пропионил-КоА-карбоксилазы. Выявленным вариантам были присвоены критерии патогенности в соответствии с рекомендациями American College of Medical Genetics and Genomics (ACMG).</p></abstract><trans-abstract xml:lang="en"><p>Propionic acidemia is a rare autosomal recessive metabolic disorder, characterized as classic organic acidemia. The article represents biochemical and molecular characterization of 16 patients diagnosed with propionic acidemia in Russia. Symptoms appeared during the first months after birth in most cases. Poor feeding, seizures, hypotonia, lethargy were the most frequent symptoms. Biochemical tests (GC-MS and MS/MS) showed elevated 3-hydroxypropionic acid, methylcitrate, propionylglycine, C3 in patients blood. Six undescribed earlier variants were found as a result of PCCA &amp; PCCB (4 variants - PCCA, 2 - PCCB) genes DNA-tests. Variant c.655-2A&gt;G in PCCB is the most frequent in this group (17.2%). Localization of missense variants and their effect on protein was demonstrated using propionyl-CoA carboxylase 3D model. New variants were classified according to the American College of Medical Genetics and Genomics (ACMG) guidelines.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пропионовая ацидемия</kwd><kwd>биохимия</kwd><kwd>гены PCCA</kwd><kwd>PCCB</kwd></kwd-group><kwd-group xml:lang="en"><kwd>propionic acidemia</kwd><kwd>biochemistry</kwd><kwd>PCCA</kwd><kwd>PCCB</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">Новиков П.В., Николаева Е.А., Боровик Т.Э. и др.
