    Abstract:
    Ovarian cancer (OC) is one of the leading cause of cancer death in women. Inherited BRCA1 and BRCA2 mutations strikingly increase OC risk (with lifetime risk estimates ranging at 10-60%). Mutation 1100delC in CHEK2 gene was shown to be associated with breast cancer in women carrying this mutation. Knowledge of the nature and frequency of population-specific mutations in these genes is a critical step in the development of simple and inexpensive diagnostic approaches to DNA analysis. The frequencies of 185delAG, 300T>G, 4153delA, 4158A>G, 5382insC mutations in BRCA1 gene, 695insT and 6174delT mutations in BRCA2 gene and 1100delC mutation in CHEK2 gene were analyzed using biochips in Russian OC patients. We studied 68 women who received a diagnosis of epithelial OC and 19 women with primary multiple tumors involving the ovaries. The 185delAG, 300T>G, 4153delA and 5382insC in BRCA1 gene were identified. The most prevailing mutation was 5382insC in BRCA1 gene (87.5% of all BRCA1 mutations OC patients, 50.0% in patients with primary multiple tumors involving the ovaries). No mutations in BRCA2 and CHEK2 genes were detected.
