Aim of the study. Aim of the study was to estimate the occurrence of pathogenic mutations in the BRCA1 gene in Russian breast cancer patients. material and methods. Complete coding sequence of the BRCA1 gene of 445 early onset breast cancer patients (under 40 years) from Novosibirsk region (Russia) were analyzed by targeted Next generation Sequencing (NgS) using Ion Torrent platform. results. Forty (9%) carriers of various pathogenic mutations were revealed. Thirty five (7,9%) patients carried 5382insC mutation, described earlier as a founder mutation for Slavic population. Five (1.1%) patients carried various pathogenic mutations, namely C61g, 462delCC, E143x, 4153delA, and IVS18+1g>T. besides, 29 genetic variants with no clinical significance or with unknown clinical significance were detected in BRCA1 gene among 445 early-onset breast cancer patients. Conclusions. Data on the frequency of genetic variations in the BRCA1 gene among early-onset breast cancer patients in the Novosibirsk Region (Russia) were obtained. Proportion of the 5382insC mutation is 87.5% of all pathogenic mutations in the BRCA1 gene found in patients.
