We have screened for germline TP53
mutations in Finnish BRCA1
mutation-negative families. This study represents the largest survey of the entire protein-encoding portion of TP53
, and indicates that mutations are only found at conserved domains in breast cancer families also meeting the criteria for Li-Fraumeni/Li-Fraumeni-like syndrome, explaining only a very small additional fraction of the hereditary breast cancer cases. © 2001 Cancer Research Campaign http://www.bjcancer.com
