Özet

Mutations in two major breast cancer susceptibility genes, BRCA1 and BRCA2, have been identified to be the most important predisposing factors for the development of breast cancer. Thus, BRCA1/2 testing is a well-established method of choice for the assessment of developing breast cancer. Accordingly, here we aimed to report novel BRCA1/2 variations and distribution of previously known mutations and their association with the clinical course of breast cancer disease. A total of 287 breast cancer patients were enrolled from January 2017 through December 2019. Of these patients, 50 of them were identified to be positive for BRCA1/2. Next Generation Sequencing analysis was performed for the screening of exonic and intronic variations of BRCA1/BRCA2 genes. Notably, novel variations of 4448 G > A (Ser1843Asn) in BRCA1, and 982dupA (Thr328AspfsTer) and 7588C > T (Gln2530Ter) in BRCA2 gene were identified. The most common variations in BRCA1 gene were 5152 + 66G > A, 442-34C > T and 5266dupC. In BRCA2 gene, the most common variations were 9097dupA, 67 + 1G > A and 1114A > C. Novel variations of BRCA1 and BRCA2 genes were identified in breast cancer and might be useful predisposing factors in breast cancer diagnosis. © 2020 Elsevier Inc.
