Translocation WebOf the 54 patients with a strong family history, 40 patients (74%) accepted the genetic test. Thirteen deleterious mutations (11 in BRCA1 and 2 in BRCA2) were identified (33%). Twenty-three of 283 patients (8%) without a strong family history underwent genetic testing and two deleterious mutations in BRCA1 were identified (9%).
