It’s clear from recent progress that DNA sequencing will soon become commonplace in medical care – it already is widely used in biomedical research. DNA sequencing costs have dropped and will soon be at $1,000 or less for an entire human genome. The cost of interpreting that data is being debated but it will no doubt drop as well. There are some important things that need to happen before sequencing for medical use can become commonplace. I’ll discuss a couple of the most critical ones below.
