One-hit effects and cancer.
This perspective on Bellacosa et al. (beginning on p. 48 in this issue of the journal) discusses the important biology of microscopically normal tissues in carriers of germ-line BRCA1 or BRCA2 mutations. The work of Bellacosa et al. is an important step toward discerning which pathways may be altered when one BRCA allele is inactivated.
