When a stranger can gain access to someone's entire genetic code by picking up a used coffee cup, it presents a whole new thicket of concerns about privacy and security.
Actually, we're already there, though we're still in the early stages of what's shaping up, after all the years of hype, as a genuine revolution. Just take a look at Rob Stein's recent series on the $1,000 genome to see how far we've come and where we're headed.
Sara Terry's first clue that something was wrong with her son, Christian, came just three weeks after he was born.
"We went to check on him, just like any parents go and check on their kids just to make sure they're breathing," says Terry, 34, of Spring, Texas. "And we found him in his crib, and he wasn't breathing. He was blue."
She and her husband were horrified. They rushed Christian to the hospital and learned he had several medical problems.
Beau Gunderson's fascinated by what he might learn from his DNA.
"I'm curious about what makes me tick, essentially," says Gunderson, 29, who writes code for a Silicon Valley startup.
So Gunderson has signed up for every genetic test he's been able to afford. And he can't wait for the price of getting his entire genetic code — his genome — to drop to about $1,000, as many are predicting is imminent.
"Yeah, if the price does drop — to a thousand bucks for example — I might pay that. That's a good personal price point for me," Gunderson said.
