Narrator: This is Science Today. Taking advantage of the great strides made in the field of genetics, researchers at the University of California, San Francisco have tracked genes that can predict an individual's response to antidepressants. Dr. Steven Hamilton, a psychiatrist and human geneticist, led the study.
Hamilton: We've taken advantage of a U.S. and NIH-funded clinical trial in which four thousand people were taking a single antidepressant in order to determine what is the best approach for dealing with depression and what we've been able to do is get DNA from about two thousand of these people, allowing us to analyze the DNA to determine whether there's some differences between people who are taking anti-depressants that can predict or influence whether they're going to respond to these drugs or not.
Narrator: Hamilton says this information can help patients suffering from depression receive the best treatment.
Hamilton: Hopefully, we can move this forward by having some sort of predictive test that says that the likelihood that you'll respond or not respond is higher.
