San Francisco—The discovery of gene mutations linked to cancer or other serious illnesses has paved the way to genetic testing to determine if an individual, typically someone from a high-risk family, carries a flawed gene.
A positive genetic test may help patients by alerting them to the need for screening or preventive measures. But many people who are good candidates may be reluctant to undergo testing because they fear that insurers and employers will use genetic information to discriminate against them.
