In DNA, a Scary Crystal Ball
"Your life expectancy hasn't changed," the doctor told him. Then came the bad news. During the course of three stories, science writer John Lauerman met with Harvard scientists, genetic counselors and members of his family on a journey to discover the promise and perils of genetic testing -- his own. Seeking clues to his future health, Lauerman showed how DNA sequencing is helping doctors diagnose and treat diseases, and he identified coming breakthroughs in the genome industry. Four months after he gave blood for a new type of DNA test, Lauerman's health became part of the story when he learned he has a rare gene variant linked to "cancer-like" diseases. Now he must confront his medical future.
