A new study analyzed the DNA of an entire family of four for the first time. The study was made possible by cheap sequencing from Calif.-based Complete Genomics, which offers sequencing for a mere $5,000 per genome.  (Source: ABC News)
Someday soon your family might be able to get its genome sequenced too

The Institute for Systems Biology (ISB) and the University of Luxembourg have published an intriguing new study in the journal Science, in which they detail the genome sequencing and analysis of a family of four humans.  The sequencing marks the first time a family of four has had their genomes sequenced, and follows many individual sequencing projects over the last decade.

David Galas, PhD, a corresponding author on the paper who works at the ISB, says the work offers a glimpse of how family genome sequencing could aid in identification and understanding of disease.  He states, "We were very pleased and a little surprised at how much additional information can come from examining the full genomes of the same family.  Comparing the sequences of unrelated individuals is useful, but for a family the results are more accurate. We can now see all the genetic variations, including rare ones, and can construct the inheritance of every piece of the chromosomes, which is critical to understanding the traits important to health and disease."

Currently, genome sequencing prices have been plummeting thanks to better techniques and equipment.  In 2007, the cost was around $1M USD -- in 2008 Applied Biosystems of Foster City, California sequenced the genome of a Nigerian man for only $60,000.  In 2009, Complete Genomics, based in Mountain View, California, claimed it could read entire human genomes for $5,000.  

Nonetheless, the number of complete genomes sequenced remains relatively low.  The X Prize foundation has offered a $10M USD reward to the first person or firm that can sequence 100 human genomes in less than 10 days for less than $10,000 each.

The new sequencing project at the ISB emphasizes the benefits of sequencing for the masses.  ISB and the University of Luxembourg actually partnered with Complete Genomics to complete the sequencing.

The sequencing allowed the identification of genes related to two genetic disorders that the children had -- Miller syndrome, a rare craniofacial disorder, and primary ciliary dyskinesia (PCD), a lung disease.  In the case of Miller's syndrome, the sequencing allowed the number of candidate genes (genes that might cause the disorder) to be reduced to four.

ISB President Leroy Hood, MD, PhD, comments, "An important finding is that by determining the genome sequences of an entire family one can identify many DNA sequencing errors, and thus greatly increase the accuracy of the data.  This will ultimately help us understand the role of genetic variations in the diagnosis, treatment, and prevention of disease."

Another exciting result from the study is the first direct measurement of the intergenerational mutation rate.  The researchers found that the rate works at half the rate predicted by researchers, hinting at a potentially slower pace of human microevolution.  

Concludes Professor Galas, "This estimate could have implications for how we think about genetic diversity, but more importantly the approach has the potential to increase enormously the power and impact of genetic research.  Our study illustrates the beginning of a new era in which the analysis of a family's genome can aid in the diagnosis and treatment of individual family members. We could soon find that our family's genome sequence will become a normal part of our medical records."

Understanding (and eventually adjusting) the human genome will indisputably be the number one technological advance of the next century. For mitigating and curing disease, and improving health, happiness, and even eventually lifespan, progress here is key.

When they can increase lifespan, will we then be required to work longer before retirement? How fast will the population increase once we can cure so many diseases?

For every upside, there is usually a downside to be dealt with. I'm not saying I hope it doesn't happen, I would like to be around when we can finally have space travel and such, but just asking the questions that need to be asked.

No one is legally required to work. The government simply won't provide for you until you reach a certain age.

"How fast will the population increase once we can cure so many diseases?"

In nations such as Japan, Russia, Germany, Poland, Hungary...population is decreasing, not increasing. In other nations, the old 1960s zero-population-growth fallacy is luckily dying away. More people is, in general, a good thing, not bad.

In any case, the notion that its better to let sick people die than cure them, just to control population growth, is rather horrifying.

That's eugenics... a policy developed by the progressives in the early 1900's and co-opted by the nazi's. Its probably also why a lot of people are a little worried about the government running health care in this country.

I'd be even more worried about the health insurance/pharma companies running health policy.

You shouldn't take what Glenn Beck says seriously, he has an agenda and currently it's going after progressives. Eugenics wasn't a Progressive invention.

I don't know what Glenn Beck may have said on the subject, but your history is quite wrong. Eugenics sprang out of Social Darwinism and the Progressive Movement..the same folks who advocated replacing laissez faire capitalism with the "managed capitalism" we have in the US today.

The Progressives claimed that Eastern Europeans (the primary source of US immigration at the time) had defective genes. With a wealth of data and scientific reports, they claimed they would 'solve the problem' through sterilization of individuals with defective germ plasm, and lead us to a new era of 'scientific management' of human problems.

So please, don't attempt to rewrite history to fit your political goals.

I'm not trying to rewrite history, I said it wasn't a progressive invention and I stand by that, there might have been progressives supporting it at one time or another, but so did someone very much to the right(Hitler) if I had a political agenda I would say it was a conservative invention, I don't believe that either, so please don't put words in my mouth.

"there might have been progressives supporting it at one time or another..."

Progressives were the originators of the movement, and the first to promote Eugenics as a serious alternative. Don't shy away from the facts because you don't like them.

"...but so did someone very much to the right(Hitler)"

Hitler was not "very much to the right". His initial power base was populist: workers unions and the lower middle class, and his early campaign platform was predicated on socialized control of big business and finance, centralized planning, and other standard elements of liberal philosophy. Strip away some of the militant nationalism, and Hitler's rhetoric was identical to the progressive movements in the US and Europe at the time.
