- Description
- Mutation in the BRCA1 gene increases the risk of the person developing breast and/or ovarian cancer. The prevalence and spectrum of large genomic rearrangements (LGRs) varies considerably among different tested populations. In our previous study we described three LGRs in BRCA1 (exons 13-19, exon 17 and exon 22) in Polish families at high risk of breast and ovarian cancer. In this study we analyzed a group of 550 unselected women with ovarian cancer for the three previously identified LGRs. We used a rapid, single-step and closed-tube method: high-resolution melting analysis (HRMA). In this group of unrelated patients diagnosed with ovarian cancer we found three cases with the same deletions of exon 22. This is the first recurrent large deletion in BRCA1 found in Poland. We conclude that screening for the exon 22 deletion in BRCA1 should be included in the Polish BRCA1 genetic testing panel and possibly extended into other Slavic populations.
