The
Economist has a short series of articles on consumer DNA testing:
"What lies within" (The personal genetic-testing industry is under fire, but happier days lie ahead)
"Reading genes" (Alas, a DNA test probably won’t reveal your future. But a crackdown on consumer genetics is unwise)
"The part where I find out that I may get fat" (What our science correspondent found out about herself when she tried commercial gene testing)
"The part where I find out the government doesn't like what I'm doing"
(My own piece on this topic is available at PajamasMedia: "
Should You Be Allowed to Know What’s in Your DNA?")
