stages. Here we have reviewed studies that suggest these are important avenues for exploration, and we provide examples of studies that have begun to address these kinds of questions. We note that these new areas of study will present their own challenges, as well. Like gene identification studies, large sample sizes will be necessary, and replication across studies will be critical. However, ultimately, this information will enable us to develop more informed, tailored prevention and intervention efforts; it is the prevention extension of personalized medicine. In our excitement over the potential of genetics to develop more effective and tailored treatment, we must not forget its potential to also inform the prevention of disorders.
