All hail Khan!

Congratulations to Razib Khan, the noted genetics blogger, on the birth of his son. Born just last week, Razib’s son is already making the news:

An infant delivered last week in California appears to be the first healthy person ever born in the U.S. with his entire genetic makeup deciphered in advance.

Razib, a graduate student at a lab at UC Davis in California, had some genetic material from his in-womb son from a fairly standard CVS test.

When Khan got the DNA earlier this year, he could have ordered simple tests for specific genes he was curious about. But why not get all the data? “At that point, I realized it was just easier to do the whole genome,” he says. So Khan got a lab mate to place his son’s genetic material in a free slot in a high-speed sequencing machine used to study the DNA of various animal species. “It’s mostly metazoans, fish, and plants. He was just one of the samples in there,” he says.

The raw data occupied about 43 gigabytes of disk space, and Khan set to work organizing and interpreting it. He did so using free online software called Promethease, which crunches DNA data to build reports—noting genetic variants of interest and their medical meaning. “I popped him through Promethease and got 7,000 results,” says Khan.

Promethease is part of an emerging do-it-yourself toolkit for people eager to explore DNA without a prescription. It’s not easy to use, but it’s become an alternative since the FDA cracked down on 23andMe.

Craig Venter was the first person to have his genome sequenced, that was in 2007. Now, just seven years later, costs have fallen by a factor of 10,000.  Personal genome sequencing is going to become routine regardless of the FDA.
