In the past decade, DNA sequencing has gotten really, really cheap, paving the way for an onslaught of direct-to-consumer genetic testing companies that purport to offer the answers to everything from what wine you might like to the type of exercise optimised for your body.
For an initial fee of $US80 ($[AU]101), the company [Helix] sequences what’s known as the exome, the 20,000 or so most important genes of the human genome. […] Customers can then pick and choose what pieces of information they might like from their genome, purchasing third-party DNA apps from the Helix store.
