Abstract
Familial breast cancer represents 5 to 10% of the total of breast cancer. Three years ago, we undertook the study of the BRCA1 gene infemales with early breast cancer and with familial breast cancer in our Autonomous Community.The Objetives of this study were first to find out what kind of BRCA1 mutations exist in our population, and second to determine if the highprevalence of this cancer in The Barque Population could be due to these mutations.Patients and methods: 149 patients with early breast cancer ( 40 years) and with familial cancer ( 50 years) were studied. The 21 ancodingBRCA1 exons were studied by PCR, CSGE and sequencing.Results: Nine mutations were found: two of them don´t produce an amino acid change, a third one lies in the 20 intron and consequently, itshouldn´t aggect the protein processing, and six mutations were missence mutations.Conclusions: These preliminary results show a 6.04% frequency of mutations in our Community, which is similar to that reported by otherauthors.
