How genetic testing may spot disease risk

Wall Street Journal, May 4, 2010

The tests, now taking off at a number of leading research hospitals, remain controversial amid debate over whether the information they yield will lead to improved outcomes and justify the additional cost. But a study surrounding a healthy 41-year-old man with some family history of heart disease illustrates how genetic testing can lead to early treatment and may stave off heart problems, the Wall Street Journal reports.
