ПАЦИЕНТЫ И МЕТОДЫ. В исследование были включены 98 пациентов с различными генотипами. РЕЗУЛЬТАТЫ. Полученные данные показали частоту развития диабетической нефропатии (ДН) у лиц с ТТ генотипом (0,30) выше по сравнению с пациентами, имеющими генотип СС (0,11) и СТ (0,09) (р&lt;0,05). ЗАКЛЮЧЕНИЕ. Результаты исследования подтверждают, что у пациентов с сахарным диабетом I типа определение ТТ генотипа может быть использовано в качестве одного из критериев прогноза развития ДН в клинической практике.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM of the investigation was a 7-years catamnestic observation of patients with I type diabetes with different allele variants of the methylenetetrahydrofolate reductase (MTHFR) gene. PATIENTS AND METHODS. The investigation included 96 patients with different genotypes. RESULTS. The data obtained  have shown the frequency of the development of diabetic nephropathy (DN) in patients with TT genotype (0.30) to be higher than in patients having genotype ОО (0.11) and CT (0.09) (p&lt;0.05). CONCLUSION. The results of the investigation have confirmed that the genotype TT determination in patients with I type diabetes mellitus can be used as one of criteria of prediction of the development of DN in clinical practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диабетическая нефропатия</kwd><kwd>генетика диабетической нефропатии</kwd><kwd>С677Т полиморфизм  МТГФР</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetic nephropathy</kwd><kwd>diabetic nephropathy genetics</kwd><kwd>C677T MTHFR polymorphism</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">Дедов ИИ, Кураева ТЛ, Петеркова ВА.
