Thanks to genetic testing, I now know that If it were biologically possible to have a baby with Mark Henderson, Science Editor of the Times, that baby would be certain to have wet earwax.
And he or she would definitely not have cystic fibrosis. Science!
This is all in aid of a session at the UK Conference of Science Journalists exploring the world of genetic testing, hosted by Mark, Daniel Macarthur from Genomes Unzipped and others. As part of the session, various journalists were offered the chance to get their genes tested for free by one of the three leading companies providing such services. I had a brief chat to Daniel about it, got his recommendations, and signed up. Four days later, a testing kit from 23andme arrived on my desk. I knew that 23andme had recently swapped some samples in a technical blunder but after reading Daniel’s blog, I was convinced that it was unlikely to happen again. If it did, I would enjoy finding out that I was secretly a black woman.
An hour later, I had delivered a dollop of my finest sputum into the tube they provided… and realised that I was only about a third of the way up to the fill-line. Doing this in the middle of the office was not a smart move. Ten further minutes later, and to a crescendo of laughter from my colleagues, the tube was full, sealed in a biohazard bag (I try not to take this as an indictment of my breath) and sealed in a Fed-ex envelope. Four weeks later, the results arrived. The whole process couldn’t have been simpler.
In fact, it was perhaps too easy. Signing up to the 23andme site, verifying the code on my testing kit and preparing the sample took little more than an hour. I had to read and agree to documents that reassured me about the privacy of my information and provide consent to analyse my samples. The same documents warn about the possible psychological consequences of finding out your data and the limtiations of the resulting information (more on these later; meanwhile, I’ve uploaded the full consent form to Posterous so you can see it for yourself). Nonetheless, I was well aware of these risks. I could have found out that I have substantially high odds of developing life-threatening diseases. I could have discovered that I’m not actually related to my parents. This is not a bottle one can re-cork.
