Выполнено сравнение групп между собой и с группой без мутаций. Для пациенток с мутациями гена CHEK2 были характерны опухоли с более высокой клинической стадией и б?льшим размером, менее характерны опухоли с негативным статусом по рецепторам эстрогена и с двойным негативным рецепторным статусом, чем для пациенток с мутациями гена BRCA1. Подгруппа пациенток с мутацией BRCA1 5382insC отличалась от подгруппы с мутациями BRCA1 300T&gt;G, 4153delA, 185delAG в 3 раза большей частотой присутствия рака молочной железы и/или яичников в семейном анамнезе</p></abstract><trans-abstract xml:lang="en"><p>There has been performed the analysis of the clinico-morphological characteristics of breast cancer in 849 patients, including groups with mutations of the BRCA1, BRCA2 and CHEK2 genes. There has been performed the comparison of the groups with each other and with the group without the mutation. Spread tumors and tumors with higher clinical stage have been more common and tumors with negative estrogen receptor status and double- negative receptor status have been less common for patients with CHEK2 mutations than patients with BRCA1 mutations. The three times greater frequency of the presence of breast cancer and/or ovarian cancer in family history has been difference between the subgroups of patients with a 5382insC mutation and the subgroups with 300T&gt; G, 4153delA, 185delAG mutations of the BRCA1.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>BRCA1</kwd><kwd>BRCA2</kwd><kwd>CHEK2</kwd><kwd>герминальные мутации</kwd><kwd>клинико-морфологические характеристики</kwd><kwd>breast cancer</kwd><kwd>BRCA1</kwd><kwd>BRCA2</kwd><kwd>CHEK2</kwd><kwd>germline mutations</kwd><kwd>clinico-morphological characteristics</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">Breast cancer susceptibility: current knowledge and implications for genetic counselling / T.
