Beware accuracy of mail-in genetic tests

“The Perfect 46” is a coming movie in which people are routinely tested to find an ideal genetic partner with whom to create a child. In the real world, things are almost as far-out. Some companies can screen and alert you to DNA variants that might combine with your partner's to produce an offspring with a rare, single-gene disease, such as cystic fibrosis. Others look for genetic indications that you could develop a disease down the road, so you can make decisions about prevention or medical treatment.
