В России данный метод пока не нашел практического применения. Целью работы явился анализ эффективности использования метода HRMA на первом этапе молекулярно-генетической диагностики муковисцидоза у детей. Материал и методы. Представлены результаты валидационного молекулярно-генетического исследования с помощью метода HRMA для 43 контрольных образцов ДНК, полученных у детей с подтвержденным диагнозом «муковисцидоз» и известными мутациями в гене CFTR . Результаты. Специфичность молекулярно-генетической диагностики муковисцидоза с осуществлением метода HRMA на первом ее этапе составила 100 %, чувствительность - 97,3 %. В двух образцах c протяженной делецией во 2-м и 3-м экзонах в гетерозиготном состоянии паттерн плавления был идентичен паттерну для «дикого» типа. Заключение. Высокая эффективность метода HRMA обосновывает возможность его внедрения в практику на первом этапе молекулярно-генетической диагностики муковисцидоза у детей для сокращения времени на проведение исследования, что в абсолютном большинстве случаев позволяет установить тип мутации в гене CFTR . Протяженные делеции/инсерции и сложные перестройки в гетерозиготном состоянии не выявляются с помощью метода HRM. Для определения подобного типа мутаций требуется методика мультиплексной амплификации проб с помощью лигирования.</p></abstract><trans-abstract xml:lang="en"><p>High-resolution melting analysis (HRMA) is promising for preliminary scanning of the nucleotide sequence of the cystic fibrosis transmembrane conductance regulator gene ( CFTR ), which mutations are responsible for the development of cystic fibrosis. In Russia this method has not yet found practical application. The aim of this work was the analysis of the efficiency of the HRMA method at the first stage of molecular diagnostics of cystic fibrosis in children. Materials and methods. In order to validate the new technique for extended molecular genetic analysis we examined 43 control DNA samples obtained from children with confirmed cystic fibrosis diagnosis and known CFTR mutations. Results. The specificity of cystic fibrosis molecular diagnostics with the implementation of the HRMA method was 100 %, the sensitivity was 97.3 %. In two samples with extended heterozygous deletion of the 2nd and 3rd exons melting patterns were identical to the wild type ones. Conclusions. The high efficiency of the HRMA method proves the possibility of its usefulness in clinical practice at the first stage of cystic fibrosis molecular diagnostics in children toward the reduction of the diagnostic search duration. In most cases this method allows to determine CFTR gene mutation type. Long deletions/insertions and complex heterozygous restructurings still cannot be detected using HRMA. Multiplex ligation-dependent probe amplification is required to determine this mutation type.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молекулярная диагностика</kwd><kwd>анализ кривых плавления высокого разрешения</kwd><kwd>муковисцидоз</kwd><kwd>дети</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">Красовский С.А., Каширская Н.Ю., Черняк А.В., Амелина Е.Л., Петрова Н.В., Поляков А.В., Кондратьева Е.И., Воронкова А.Ю., Усачева М.В., Адян Т.А., Степанова А.А., Алимова И.Л., Ашерова И.К., Байкова Г.В., Басилая А.В., Бойцова Е.В., Борисов А.В., Брисин В.Ю., Васильева Е.А., Васильева Т.Г., Водовозова Э.В., Воронин С.В., Гаймоленко И.Н., Голубцова О.И., Горинова Ю.В., Назаренко Л.П., Одинокова О.Н., Гембицкая Т.Е., Никонова В.С., Дьячкова А.А., Сергиенко Д.Ф., Енина Е.А., Ерзутова М.В., Зинченко Ю.С., Зоненко О.Г., Иванова Д.М., Ильенкова Н.А., Кадырова Д.В.
