Dear Jane, Here is a web page detailing the budget: http://www.ornl.gov/TechResources/Human_Genome/project/budget.html As pointed out on this page, the figure of $3 billion covering 1990-2003 does not just mean the sequencing of the human genome, but also a broad array of scientific activities related to genomics. There have been a number of benefits, and most of the benefits will show up in the future. Some of these benefits include: 1. The scientific value of the sequence of the human and model organism genomes, which will have a fundamental impact on medicine and biological science for decades to come (see below). 2. The scientific and industrial value of a sequencing project of this scale. This project created a market for sequencing technologies, creating advances in speed and scale that might not have happened otherwise. It is comparable to what military contracts did for the semiconductor industry in the 1970s. 3. The training and career opportunities provided for many people in science. This project trained a new generation of young scientists to work in a way that their older colleagues could not possibly imagine. 4. An infusion of funding into Ethical, Legal, and Social Issues. A small part (3-5%) of the funding for this project funded studies in ELSI. The people doing this work had an opportunity to explore the social impact of the project; the scholars involved had a wonderful opportunity to develop their careers in a field that is often very short of funding. Please see: http://www.ornl.gov/TechResources/Human_Genome/elsi/elsi.html Let me expand a bit on the scientific impact of this project. When the project was first proposed, many in the scientific community were reluctant to see the project undertaken. The cost was unprecedented, there were many unknowns, and the value of the information was debated. Now that the sequence is essentially finished, it is clear with hindsight that these concerns were unfounded. The project was finished ahead of time and under budget. In order to demonstrate the feasibility and to develop technologies, the genomes of several other model organisms were sequenced. These included yeast, the fruit fly Drosophila, the nematode C. elegans, the mouse, and other species that are on the way. This will allow a complete catalog of all human genes and the comparative analysis of the equivalent genes in laboratory organisms. The argument at the outset was not whether we should sequence the genome, but whether we should wait until it was cheaper. There was also some concern that funding of this project would deplete funding for other biological research. To some extent, this concern was addressed by using some of the human genome project funding for work on model organisms. The practical impact of this project will transform medicine. Up to this point, most drugs were discovered by looking for natural substances that had pharmacologic effects and making many chemical look-alikes. There was no knowledge of the targets of these drugs. We are now in an era where drugs will be designed rationally, by looking for targets in the human genome and developing small molecules to affect them. As the cost of sequencing continues to fall, it is conceivable that individual patients will have parts of their genomes sequenced in order to determine how their own genetic individuality affects drug response. Many people experience severe reactions to particular drugs because of genetic variation in drug metabolism genes. Gene therapy will certainly also become more widespread. The generalized advance in sequencing technology spurred by the human genome project has had other benefits. The rice genome was recently sequenced; other plant genomes will follow. This will allow tremendous advances in agriculture. Several agriculturally important animal genomes are also going to be sequenced. None of this is funded by the human genome project, but it has benefited from it. Consider also the SARS epidemic. The complete SARS genome was sequenced within a few weeks of the reports of the first outbreak. To address your original question the project was funded using taxpayer money through NIH and the Department of Energy (which has experience managing large projects). You also ask whether the money could have been better spent on other things. This is a matter of opinion, and is not really a scientific question. First, it is possible that we might have carried out another large scientific project with a $3 billion price tag. Such a project would have to have practical impact that Congressman and the general public could understand. What if, for example, we asked a group of ten of the best physicists in the country to come up with a $3 billion project. They might propose building a huge particle accelerator, plan an extraordinary series of unmanned space missions, build a radio telescope on the far side of the moon, whatever. How could we pitch this project to the general public? It is very easy for people to understand the impact of biomedical science. It is not so easy to understand what the benefits of advances in our understanding of the universe would be. The consequence of this is that they don't get big projects unless they have political appeal, such as the Space Station. For the sake of comparison, NASA's annual budget is around $3 billion, most of which goes to the Space Shuttle and Space Station. It is also a fair question whether we should have spent $3 billion on something outside of science. In round numbers there are just over 250 million people in the United States. That's $12 per person. We could have mailed everyone a gift certificate to Amazon.com and told them to educate themselves, but we certainly couldn't have provided health insurance to the 40 million people in this country who don't have it. We might have used $3 billion to reduce the national debt, but since it is $6.4 trillion as I write this, that wouldn't have much of an impact.
