The Human Genome Project, Then and Now

An early advocate of the sequencing of the human genome reflects on his own predictions from 1986.

Walter Bodmer, along with Walter Gilbert, a 1980 Nobel laureate in chemistry and a Harvard University professor, wrote opinions advocating for a project to sequence the human genome in the premier issue of The Scientist magazine, published October 20, 1986.

In The Scientist’s first issue, Walter Bodmer, then Research Director at the Imperial Cancer Research Fund Laboratories in London, and later the second president of the Human Genome Organisation, wrote an opinion about the potential of a Human Genome Project (HGP). Now, more than a decade after the first draft genome was published, he reflects on the accuracy of those 1986 predictions.

In 1986 Bodmer predicted: the human genome would allow the characterization of ?…10,000 or so basic genetic functions…?In 2011 Bodmer says: "The '10,000 or so basic genetic functions' were not to be equated to genes, but to clusters of genes with related functions, and was not far off the mark. Now, however, we know that multiple splice products and considerable numbers of nonprotein coding, yet functional, sequences greatly extend the potential complexity of the human genome beyond the bare count of some 20,000–25,000 genes."

1986: ?Given a knowledge of the complete human gene sequence, there is no limit to the possibilities for analyzing and understanding…essentially all the major human chronic diseases…?2011: "Now, with next-generation sequencing, one can even identify a mutant gene in a single appropriate family."

1986: “The project will provide information of enormous interest for unraveling of the evolutionary relationships between gene products within and between species, and will reveal the control language for complex patterns of differential gene expression during development and differentiation.” 2011: “This has been achieved because, as expected, the HGP generated a huge amount of information on other genomes. However, only now is the challenge of the genetics of normal variation, including, for example, in facial features which are clearly almost entirely genetically determined, being met. Next, perhaps, will come the objective genetic analysis of human behavior.”

1986: ?The major challenge is to coordinate activities of scientists working in this field worldwide.?2011: "Collaboration has proved to be fundamental to the success of the Human Genome Project, which set the stage for global cooperation and, most importantly, open exchange and availability of new DNA sequences, and, more generally, large data bases of information."

1986: “The project will include…development of approaches for handling large genetic databases.”2011: “As predicted, there have been major developments in the ability to handle large databases. Accompanying this have been new approaches to data analysis using, for example, Markov Chain Monte Carlo simulations that are hugely computer intensive.

The most surprising, and certainly not predicted development, has been the extraordinary rate of advance first in the techniques for large scale automated genotyping, then in whole genome mRNA analysis and finally in DNA sequencing where the rate of reduction in cost and increase in speed of DNA sequencing has exceeded all expectations and has even exceeded the rate of developments in computing. This has, for example, made population based whole genome sequencing more or less a reality.

Perhaps one of the greatest future technological challenges will be to apply these techniques to single cells and to achieve a comparable level of sophistication of cellular analysis, to that we now have for working with DNA, RNA, and proteins.”

1986: “We should call it Project 2000.”2011: “This prediction also came to pass, with a little political license. I am referring to the fact that Bill Clinton and Tony Blair announced the completion of the project on 26th June 2000, while the first proper publication of a (very) rough draft was not till February 2001 and it took several more years until a fully reliable complete sequence became available. The public announcement was no doubt politically motivated with, I am sure, support from the scientists, to promote what was being done and have something to say at the beginning of the new millennium. An intriguing interaction between science and politics, that in contrast for example to the Lysenko episode in the Soviet union, was quite harmless and may even have been of benefit.

It seems that we are still so far from "understanding... essentially all the major human chronic diseases" dispite all the progress in genome sequencing. We have good understanding for some rare conditions resulting from single gene coding errors but our understanding of common chronic diseases remains low - let alone our ability to treat any of these diseases based on genomically informed interventions. Perhaps one could even say that at this stage, when it comes to common chronic diseases, the main learning is that the answer is NOT in our genes. The next wave of enthusiasm is shifting in two directions first to more extensive data in the hope that this will reveal more explanation from the statistics the second is towards epigenetics and what regulates gene expression. But could it be that we're looking in the wrong places and that the cause of these diseases lies eleswhere? Might it have something to do with the way we choose to live and treat our bodies?
