[Germ-line mutations of the BRCA1 gene in northeastern France].
Thirty-seven breast/ovarian or breast-only cancer families selected on a regional basis have been analyzed for mutations at BRCA1. By combining direct sequence analysis and protein truncation test, mutations were detected in 14 families (38%). We found seven different mutations, two of which have not been described before. Mutations at BRCA1 were present in 60% of breast/ovarian and 32% of breast-only cancer families. Mutations were frequent in families with at least one breast cancer case before age 40 (44%) and/or one bilateral breast cancer case (54%). Two mutations, namely 3600del11 and G1710X, are frequent in the population native from northeastern France. Oriented BRCA1 analysis should facilitate carrier detection in breast and/or ovarian cancer families stemming from this French area.
