The cause of Li-Fraumeni syndrome, a rare group syndrome of familial cancers, has recently been identified. Patients with this inherited condition are highly susceptible to specific neoplasms, including early-onset breast cancers. The available evidence links Li-Fraumeni syndrome to inherited mutations of the tumor suppressor gene p53. Moreover, somatically acquired p53 mutations and gene deletions are common feature in breast cancer of sporadic origin. These findings suggest that germline p53 mutations are important in familial and, possibly sporadic, breast tumors. We have therefore screened lymphocyte DNA from 19 unrelated bilateral cancer patients for germline p53 mutations in exons 5, 6, 7 and 8. We have however detected no germline mutations by means of the single-strand confirmation polymorphism technique in any of the lymphocyte DNAs examined and conclude that p53 mutations are not generally involved in bilateral breast cancer.
