Abstract

The hereditary breast cancer syndrome accounts for up to 10% of all breast cancers and is characterised by a high level of genetic heterogeneity. Two major susceptibility genes, BRCA1 and BRCA2, have been identified to date, and are thought to be responsible for as many as 80% of all hereditary breast cancers. The risks associated with predisposing mutations in these genes are high, even if they may vary among families. The phenotype also varies (breast, ovarian and other cancers) and may be partly influenced by the location of the mutation within the gene sequence. While little is known regarding BRCA2 biological function, recent studies on BRCA1 suggest that it is probably involved in DNA recombination and/or repair processes.
