ДНК была получена из фибробластов больного муковисцидозом согласно общепринятым методикам. Сконструированы праймеры к фрагменту ДНК в 10-м экзоне гена CFTR, в котором локализована одна из часто встречаемых мутаций - F508del, обусловливающая муковисцидоз. С помощью ПЦР-амплификации получен фрагмент ДНК, в котором содержится данная мутация. Электрофорез амплифицированного материала выявил один продукт ДНК размером около 153 пар нуклеотидов. Методом секвенирования по Сэнгеру установлена природа и последовательность нуклеиновых оснований выделенного фрагмента ДНК. Сравнение данных о нуклеотидной последовательности, полученных после секвенирования фрагмента у больного муковисцидозом, с аналогичными данными здорового человека показало наличие мутации на уровне 10-го экзона в положении 1521-1523 кодирующей последовательности гена CFTR, представляющей собой выпадение трех пар нуклеотидов, которая, по общепринятым представлениям, относится к мутации F508del. Анализ данных секвенирования позволил отнести данную мутацию к разряду компаудных гетерозигот.</p></abstract><trans-abstract xml:lang="en"><p>Molecular genetic analysis of DNA patient with cystic fibrosis to determine the nature of mutation to be the reason of this disease. DNA was obtained from fibroblast of given patient according to generally known methods. For that a pair of primers to DNA fragment in 10 exon were a mutation conditioning cystic fibrosis was designed. With help PCR-amplification an amplicon containing desired mutation. The electrophoresis of amplified material one band in DNA of which about 153 nucleotides are contained has shown. The nature and sequence of nucleotides in this fragments were established. A comparison of sequence date for this fragments of cystic fibrosis patient with date of health human has shown existence of mutation on the level of 10 exons at position 1521-1523 of the coding sequence of the CFTR gene, which is the loss of 3 pairs of nucleotides, which, according to conventional ideas, refers to the F508del mutation. The analysis sequence date allowed attribute to compound heterozogotes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аутосомно-рецессивное наследственное заболевание</kwd><kwd>муковисцидоз</kwd><kwd>CFTR</kwd><kwd>мутация F508del</kwd><kwd>компаудная гетерозигота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autosomal recessive hereditary disease</kwd><kwd>cystic fibrosis</kwd><kwd>CFTR</kwd><kwd>F508del mutation</kwd><kwd>compound heterozygote</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность докторам биологических наук Владимиру Евгеньевичу Падутову и Олегу Юрьевичу Баранову (Институт леса НАН Беларуси), а также кандидату биологических наук Станиславу Викторовичу Пантелееву (Институт леса НАН Беларуси) за помощь в анализе экспериментальных данных.</funding-statement><funding-statement xml:lang="en">The authors are grateful to the doctors of biological sciences Vladimir Evgenievich Padutov and Oleg Yuryevich Baranov (Forest Institute of the National Academy of Sciences of Belarus), as well as candidate of biological sciences Stanislav Viktorovich Panteleev (Forest Institute of the National Academy of Sciences of Belarus) for their help in the analysis of experimental data.</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">Identification of the cystic fibrosis gene: cloning and characterization of complementary DNA / R.
