BRCA1 mutation research in ovarian and breast cancer 17q21-linked families has yielded a large number of germline sequence variations. Somatic mutations have been uncommonly reported. We screened 81 probands with primary ovarian, peritoneal, or fallopian tube carcinoma for BRCA1 mutations. The study group was intentionally biased by the inclusion of 29 probands with a family history of ovarian and/or breast carcinoma, 13 probands diagnosed on or before age 45, seven individuals with a metachronous breast cancer and 51 tumors with BRCA1 LOH. Tumor and/or germline DNA was screened by modified techniques of single-strand confirmation polymorphism analysis, and abnormal banding patterns were sequenced to confirm mutations. Twenty-one (25.9%) BRCA1 sequence variations were identified. Eight mutations were somatic including seven null mutations. Apart from classical hereditary ovarian/breast cancer, a family history of ovarian/breast cancer defines a subset of ovarian cancer individuals with a significant likelihood of either a germline or a somatic BRCA1 gene sequence variation.
