Genetic testing leads to ethical minefield

December 7, 2007

As genetic tests multiply and become widely available, more people face a vexing question: If I discover I have a genetic mutation linked to a serious illness, am I obliged to tell family members who share my DNA?

Some experts see genetic information as an individual’s possession, akin to property, that should remain under his or her control. Others think it’s more like a joint bank account with multiple signers, and each party — family members with a common genetic heritage — should have access. (Chicago Tribune.com)
