All germ-line BRCA1 mutations identified to date have been inherited, suggesting the possibility of a large "founder" effect in which a certain mutation is common to a well-defined population group and can, in theory, be traced back to a common ancestor. Given the complexity of mutation screening for BRCA1, these common mutations may simplify the methods required for mutation screening in certain populations.
