摘要
Two cancer susceptibility genes, BRCA1 on chromosome 17q12-21 and BRCA2 on chromosome 13q12-13, are thought to be responsible for similar to 80% of families containing multiple cases of early-onset female breast cancer. Germline mutations of BRCA1 are also associated with ovarian cancer and mutations of BRCA2 are associated with an increased risk of male breast cancer, ovarian cancer, prostate cancer and pancreatic cancer. The recent isolation of both genes should make possible the identification of the genetic defect that predisposes affected individuals to breast and ovarian cancer and might lead to the use of genetic information for predictive testing.
