California Considers DNA Privacy Law

California lawmakers are weighing a bill aimed at protecting their state's citizens from surreptitious genetic testing but scientists are voicing their growing concerns that, if passed, such a law would have a costly and damaging effect on research.

The bill, dubbed the Genetic Information Privacy Act, would require an individual’s written consent for the collection, analysis, retention, and sharing of his or her genetic information—including DNA, genetic test results, and even family disease history.
