Despite significant advances in the field of early diagnosis and treatment of the disease, the survival rate of patients with this form of oncopathology is still low, which dictates the need for further study of this problem. The aim of the work was to evaluate the role of polymorphic variants <italic>rs13181 </italic>and <italic>rs238406</italic> of the <italic>ERCC2</italic> gene in the development of hereditary and sporadic forms of ovarian cancer in women of different ethnicity from the Republic of Bashkortostan. The material for the study was DNA samples of women with sporadic forms of ovarian cancer (n=182), hereditary forms of ovarian cancer (n=65) and women without cancer at the time of blood sampling (n=292) of various ethnic origins. Genotyping was performed by polymerase chain reaction (PCR) followed by analysis of restriction fragment length polymorphism. As a result of the study, an association of the <italic>rs13181*C</italic> allele of the <italic>ERCC2</italic> gene with the risk of developing hereditary and sporadic forms of ovarian cancer in women of Russian ethnicity was established. An association of the <italic>rs238406*GT</italic> genotype of the <italic>ERCC2</italic> gene with the risk of developing sporadic forms of ovarian cancer was revealed. The data obtained indicate the involvement of the studied polymorphic variants in the pathogenesis of ovarian cancer in our region.</p></abstract><trans-abstract xml:lang="ru"><p>Злокачественные новообразования яичников являются одной из наиболее часто выявляемых опухолей женской репродуктивной системы и одной из ведущих причин смертности от рака у женщин во всем мире. Несмотря на существенные успехи в области ранней диагностики и лечения заболевания процент выживаемости пациенток с данной формой онкопатологии все еще остается низким, что диктует необходимость дальнейшего исследования данной проблемы. Цель работы заключалась в оценке роли полиморфных вариантов <italic>rs13181 </italic>и<italic> rs238406</italic> гена <italic>ERCC2 </italic>в развитии наследственных и спорадических форм рака яичников у женщин различной этнической принадлежности из Республики Башкортостан. Материалом для исследования послужили образцы ДНК женщин со спорадическими формами рака яичников (n=182), наследственными формами рака яичников (n=65) и женщин без онкологических заболеваний на момент забора крови (n=292) различного этнического происхождения. Генотипирование проводили методом полимеразной цепной реакции (ПЦР) с последующим анализом полиморфизма длин рестрикционных фрагментов. В результате проведенного исследования установлена ассоциация аллеля <italic>rs13181*С</italic> гена <italic>ERCC2</italic> с риском развития наследственных и спорадических форм рака яичников у женщин русской этнической принадлежности. Выявлена ассоциация генотипа <italic>rs238406*GT </italic>гена <italic>ERCC2</italic> с риском развития спорадических форм рака яичников. Полученные данные указывают на вовлеченность изученных полиморфных локусов в патогенез рака яичников у женщин в Республике Башкортостан</p></trans-abstract><kwd-group xml:lang="en"><kwd>sporadic ovarian cancer</kwd><kwd>hereditary ovarian cancer</kwd><kwd>nucleotide excision repair</kwd><kwd>associative analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>спорадический рак яичников</kwd><kwd>наследственный рак яичников</kwd><kwd>эксцизионная репарация нуклеотидов</kwd><kwd>ассоциативный анализ</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the program for the development of bioresource collections of the Federal Agency for Scientific Organizations.
