В ретроспективном кросс-секционном анализе принял участие 31 ребёнок с РАС в возрасте от 3 до 18 лет, у которых изучали генотип CYP2C19, оценивая распределение аллелей и метаболических фенотипов с использованием международных баз данных CPIC и PharmGKB. Результаты показали высокую частоту аллеля CYP2C19*17, связанного с быстрым метаболизмом ИПП, у 32% участников, особенно в подгруппе с генетическими синдромами (42%), тогда как аллель CYP2C19*2, ассоциируемый с медленным метаболизмом, не был выявлен. Гендерное распределение аллеля CYP2C19*17 оказалось равномерным. Эти данные указывают на значительную генетическую гетерогенность метаболизма ИПП у детей с РАС и влияют на клиническую эффективность терапии. Полученные результаты подчеркивают необходимость фармакогенетического тестирования для персонализации дозировок ИПП и повышения эффективности лечения гастроинтестинальных нарушений у данной категории пациентов. Отсутствие аллеля CYP2C19*2 требует дальнейшего изучения. Интеграция генетических данных в клинические протоколы способствует развитию персонализированной медицины и улучшению качества жизни детей с РАС.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to investigate the pharmacogenetic characteristics of proton pump inhibitors (PPIs) metabolism in children with autism spectrum disorder (ASD) based on whole-genome sequencing data and pharmacogenetic testing. A retrospective cross-sectional analysis was conducted involving 31 children with ASD aged 3 to 18 years. CYP2C19 genotyping was performed, assessing allele distribution and metabolic phenotypes using international databases such as CPIC and PharmGKB. The results revealed a high frequency of the CYP2C19*17 allele, associated with rapid PPI metabolism, in 32% of participants, notably higher (42%) in the subgroup with genetic syndromes. The CYP2C19*2 allele, linked to slow metabolism, was not detected. The CYP2C19*17 allele showed an even gender distribution. These findings indicate significant genetic heterogeneity in PPI metabolism among children with ASD, impacting the clinical efficacy of therapy. The data emphasize the necessity of pharmacogenetic testing to personalize PPI dosing and improve treatment outcomes for gastrointestinal disorders in this patient population. The absence of the CYP2C19*2 allele warrants further investigation. Integrating genetic information into clinical protocols supports the advancement of precision medicine and enhances the quality of life for children with ASD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прецизионная медицина</kwd><kwd>фармакогенетика</kwd><kwd>РАС</kwd><kwd>CYP2C19</kwd><kwd>ингибиторы протонной помпы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>precision medicine</kwd><kwd>pharmacogenetics</kwd><kwd>ASD</kwd><kwd>CYP2C19</kwd><kwd>proton pump inhibitors</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">Aron D.C.
