Jordan, B. D. (1998). "Genetic Susceptibility to Brain Injury in Sports: A Role for Genetic Testing in Athletes." The Physician and Sportsmedicine 26(2): Barry Jordan discusses the role of genetic information in sport, specifically considering what might be the legal entitlements of sports organisations, if there were a test for specific kinds of genetic predisposition. The example he considers is susceptibility to brain injury and whether this might be a basis for prohibiting certain people from participating in sports like boxing.

More moderate uses of this information can include alerting atheltes to potential risks, more effective monitoring for an athlete's safety, or rule changes to reduce risk.

However, it is necessary to take into account the ethical and legal implications of such knowledge. Should sports organisations be entitled to access such knowledge or can an athlete expect for it to remain private?
