Роль генетических факторов в формировании РМЖ не вызывает сомнений. Цель исследования: Изучить роль высокопенетрантных мутаций в генах BRCA1 и CHEK2 в характере ассоциаций полиморфизма генов матриксных металлопротеиназ (ММР) с РМЖ. Материалы и методы: Для решения поставленной цели исследования были сформированы следующие три выборки: 26 больных РМЖ, имеющие высокопенетрантные мутации в генах BRCA1 (c.5266dup (5382insC), c.68_69del (185delAG), 2080delA) и CHEK2 (I157T)), 332 больных РМЖ без герминальных мутаций в генах BRCA1 (c.5266dup (5382insC), c.68_69del (185delAG), 2080delA, 4153delA), BRCA2 (6174delT) и CHEK2 (I157T) и 746 женщин контрольной группы. В работе изучены десять полиморфизмов пяти генов матриксных металлопротеиназ (MMP1, MMP2,&amp;nbsp;MMP3, MMP8 и MMP9). Анализ ассоциаций проводился методом логистической регрессии. Результаты: Генотип ТТ rs1940475 MMP8 у больных РМЖ, имеющих высокопенетрантные мутации в генах BRCA1 и CHEK2 (3,84%) встречается в 6-7 раз реже в сравнении как с пациентками, не имеющих этих мутаций (22,80% pperm=0,04), так и индивидуумами контрольной группы (26,18% ORcov=0,11 95%CIcov 0,01-0,81 pperm=0,03). Среди больных РМЖ, не имеющих высокопенетрантных мутаций в генах BRCA1 и CHEK2, с заболеванием ассоциирован полиморфизм гена ММР9: rs17576 (ORcov=0,81 pperm=0,03), rs2250889 (ORcov=0,61-0,66 pperm=0,03), rs3787268 (ORcov=2,03 pperm=0,04) и девять различных гаплотипов шести изученных локусов ММР9 (pperm&amp;lt;0,05). Заключение: Полиморфный локус rs1940475 MMP8 связан с риском развития РМЖ у женщин с высокопенетрантными мутациями в генах BRCA1 и CHEK2, а полиморфизм гена ММР9 ассоциирован с заболеванием у женщин, не имеющих данных мутаций</p></abstract><trans-abstract xml:lang="en"><p>Background:&amp;nbsp;Breast cancer (BC) is a malignant breast tumor, which occupies a leading place both in the structure of oncological diseases in women and among the causes of female mortality from malignant neoplasms. The role of genetic factors in the formation of breast cancer is beyond doubt. The aim of the study:&amp;nbsp;To study the role of highly penetrant mutations in BRCA1 and CHEK2 genes in the pattern of associations of matrix metalloproteinase genes (MMP) polymorphism with BC. Materials and methods:&amp;nbsp;To solve the research goal, the following three samples were formed: 26 BC patients with highly penetrant mutations in the BRCA1 (c.5266dup (5382insC), c.68_69del (185delAG), 2080delA) and CHEK2 (I157T)) genes, 332 BC patients without germinal mutations in the BRCA1 (c.5266dup (5382insC), c.68_69del (185delAG), 2080delA, 4153delA), BRCA2 (6174delT) and CHEK2 (I157T) genes and 746 women of the control group. Ten polymorphisms of five matrix metalloproteinase genes (MMP1, MMP2, MMP3, MMP8 and MMP9) were studied. The analysis of associations was carried out by the method of logistic regression. Results:&amp;nbsp;The TT rs1940475 MMP8 genotype in BC patients with highly penetrant mutations in the BRCA1 and CHEK2 genes (3.84%) is 6-7 times less common in comparison with both patients without these mutations (22.80% pperm=0.04) and control group individuals (26.18% ORcov=0.11 95%CIcov 0.01-0.81 pperm=0.03). In BC patients who do not have highly penetrant mutations in the BRCA1 and CHEK2 genes, MMP9 gene polymorphisms are associated with the disease: rs17576 (ORcov=0.81 pperm=0.03), rs2250889 (ORcov=0.61-0.66 pperm=0.03), rs3787268 (ORcov=2.03 pperm=0.04) and nine different haplotypes of the six studied MMP9 loci (pperm&amp;lt;0.05). Conclusion:&amp;nbsp;The rs1940475 MMP8 polymorphic locus is associated with the risk of developing BC in women with highly penetrant mutations in the BRCA1 and CHEK2 genes, and polymorphisms of the MMP9 gene are associated with the disease in women without these mutations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>ММР</kwd><kwd>полиморфизм</kwd><kwd>ассоциации</kwd><kwd>BRCA1</kwd><kwd>CHEK2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>matrix metalloproteinase genes</kwd><kwd>polymorphism</kwd><kwd>associations</kwd><kwd>BRCA1</kwd><kwd>CHEK2</kwd></kwd-group></article-meta></front><back><ref-list><title>Список литературы</title><ref id="B1"><mixed-citation>Gradishar WJ, Anderson BO, Blair SL, et al.
