Decreases in the cost of DNA sequencing have enabled substantial progress in fields ranging from archaeology and evolution to basic biomedical science. Concomitantly, there have been calls for routine genome-scale sequencing of healthy individuals in hopes of discovering clinically important information. For example, discovery of a high risk of breast and ovarian cancer due to a BRCA1/2 mutation can enable aggressive surveillance or risk-reducing surgery.
