Abstract excerpt
Mutations of the human BRCA1 and BRCA2 genes encoding tumor suppressors have been implicated in inherited predisposition to breast and other cancers. Disruption of the homologous mouse genes Brca1 and Brca2 by targeting showed that they both have indispensable roles during embryogenesis, because nullizygous embryos become developmentally retarded and disorganized, and die early in development. In Brca1 mutants,...
