Данные мутации относятся к различным типам - SNP, STR, Ins/Del - поэтому для их определения использованы технологии минисеквенирования и фрагментного анализа. Проведен анализ олигонуклеотидов для амплификации всех локусов в формате одной реакции. Технология минисеквенирования по сравнению с фрагментным анализом потребовала дополнительных этапов пробоподготовки, в связи с чем олигонуклеотиды для локусов с SNP были объединены в отдельный плекс. Для двух созданных плексов оптимизированы одинаковые состав амплификационной смеси и параметры программы ПЦР реакции, разработаны панели «бинов» для интерпретации результатов. Апробация системы подтвердила возможность определения мутаций в девяти локусах с высокой чувствительностью и воспроизводимостью.</p></abstract><trans-abstract xml:lang="en"><p>A multiplex system to detect mutations at loci rs5985, rs1799983, rs5918, rs2243093, rs4673, rs4646994, rs1722009, rs3980933, rs71103505 associated with the development of cardiovascular diseases has been developed. These mutations belong to different types - SNP, STR, Ins/Del - therefore, minisequencing and fragment analysis technologies were used to determine them. Oligonucleotide analysis was performed to amplify all loci in a single reaction format. The minisequencing technology, in comparison with fragment analysis, required additional stages of sample preparation; therefore, oligonucleotides for loci with SNP were combined into a separate plex. For the two plexes created, the same composition of the amplification mixture and parameters of the PCR reaction program were optimized, and “bin” panels were developed to interpret the results. The testing of the system confirmed the possibility of detecting mutations at nine loci with high sensitivity and reproducibility.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>фрагментный анализ</kwd><kwd>минисеквенирование</kwd><kwd>SNP</kwd><kwd>сердечно-сосудистые заболевания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fragment analysis</kwd><kwd>minisequencing</kwd><kwd>SNP</kwd><kwd>cardiovascular disease</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Финансирование работ осуществлялось в рамках Мероприятия 9 НТП Союзного государства «ДНК-идентификация».
