We Have Learned Nothing from the Genome - Craig Venter

Ain't that the truth? Full interview here:

"
PIEGEL: The genome project hasn't just raised hopes -- but also worries. Do you understand those concerns?
Venter: Yes. There are two groups of people. People either want to know the information or they prefer to live like an ostrich with their head in the sand, not knowing anything. The fear is based on the ill-founded belief that those who know the DNA sequence also know every aspect of life. This nonsense has been spread by the same geneticists who were afraid of the commercialization of this stuff. From the time of the first few discoveries of gene defects -- Huntington's disease, for example, everybody thought that if you knew your genome, you would know when you would die and what you would die from. That is nonsense.

PIEGEL: So the significance of the genome isn't so great after all?
Venter: Not at all. I can tell you from my own experience. I put my own genome on the Internet. People had the notion this was the scariest thing out there. But what happened? Nothing.
SPIEGEL: And what about the fears about the abuse of gene data through insurers or employers, for example? Do you see that as sheer hysteria?
Venter: Abuse is not a question of whether the data is available. It is an issue of laws. You can't do anything to change the availability of genetic data. Look at this bottle that you have touched -- that's all I need to obtain your entire genetic information.
SPIEGEL: How much would you be able to learn about us by doing so?
Venter: If anything, we don't really know how to read the genome and it can't tell us very much right now. So what's the ethical debate about?
SPIEGEL: The decoding of your personal genome has so far revealed little more than the fact that your ear wax tends to be moist.
Venter: That's what you say. And what else have I learned from my genome? Very little. We couldn't even be certain from my genome what my eye color was. Isn't that sad? Everyone was looking for miracle 'yes/no' answers in the genome. "Yes, you'll have cancer." Or "No, you won't have cancer." But that's just not the way it is.
SPIEGEL: So the Human Genome Project has had very little medical benefits so far?
Venter: Close to zero to put it precisely.
SPIEGEL: Did it at least provide us with some new knowledge?
Venter: It certainly has. Eleven years ago, we didn't even know how many genes humans have. Many estimated that number at 100,000, and some went as high as 300,000. We made a lot of enemies when we claimed that there appeared to be considerably fewer -- probably closer to the neighborhood of 40,000! And then we found out that there are only half as many. I was just in Stockholm for the 200th anniversary of the Karolinska Institute. The first presentation was about the many achievements the decoding of the genome has brought. Then I spoke and said that this century will be remembered for how little, and not how much, happened in this field.
SPIEGEL: Why is it taking so long for the results of genome research to be applied in medicine?
Venter: Because we have, in truth, learned nothing from the genome other than probabilities. How does a 1 or 3 percent increased risk for something translate into the clinic? It is useless information.
SPIEGEL: Do you think there will be a time when you can extract all this information to yield real medical results?
Venter: For that to happen we need a lot more information: Information about your body's chemistry, your physiology, your complete medical history, your brain and your entire life. We would need to do that a million times on different people and correlate that data with their genetic information.

Finally I think, the answer to this question is most important to subside the overblown expectations, paranoia and the future snake oil salesmen:

"SPIEGEL: Will that lead in the end to the kind of personalized medicine that genetic researchers have always touted? Each person would get his or her own personal treatment that is tailored precisely to that person's genetic make-up?
Venter: That was another one of these silly naïve notions that was out there. It's not, 'Oh, we know your genome, we're going to make this drug for you.' That will never happen. It is more important that you use the information in the genome about your personal risks and reduce them through intelligent behavior."

The genetic revolution expect's intelligent behavior from us but irony is we are expecting miracle's from the geneticists. Intelligent behavior makes it less interesting in the world longing for cognitive fluency, right?
