Patents in July 2000 have already led to more than 740 genetic tests that
are on the market or being developed, according to the National Institutes of
Health. These tests, however, show how far genetics has to go. Several years
after the debut of tests for BRCA1 and BRCA2, for instance,
scientists are still trying to determine exactly to what degree those genes
contribute to a woman’s cancer risk. And even the most informative
genetic tests leave plenty of questions, suggests Wendy R. Uhlmann, president
of the National Society of Genetic Counselors. “In the case of
Social issues can get in the way, too. After Kelly Westfall’s mother
tested positive for the
The HGP’s Collins is among those calling for legislation to protect people like Westfall. A patchwork of federal and state laws are already in place to ban genetic discrimination by insurers or employers, but privacy advocates are lobbying Congress to pass a more comprehensive law. In February 2000, President Clinton signed an executive order prohibiting all federal employers from hiring, promoting or firing employees on the basis of genetic information. It remains to be seen whether private companies will follow suit.
In the meantime, Celera is now ready to hawk its Homo sapiens genome, complete with crib notes on all the genes, to online subscribers worldwide. “It’s not owning the datait’s what you do with it,” Venter remarks. He envisions a Celera database akin to Bloomberg’s financial database or Lexis-Nexis’s news archives, only for the genetics set. Which 300 genes are associated with hypertension? What, exactly, does each gene do? These are the kinds of queries Celera’s subscribers might posefor a price. As of this writing, Celera planned to offer a free peek at the raw genome data online, but tapping into the company’s online toolkit and full gene notes will cost corporate subscribers an estimated $5 million to $15 million a year, according to Gilman. Academic labs will pay a discounted rate: $2,000 to $15,000 a year.
Internet surfers can now visit GenBank for free. With all this information available, will scientists really pay Celera? Venter thinks so. “We just have to have better tools,” he says. For genomics, that is becoming a familiar refrain.
Thousands of people have contributed to the Human Genome Project (HGP).
Their efforts must be paid for, collated, reviewed, corrected, and combined
with the contributions of others, if the project is not to degenerate into
chaos. As with any major undertaking, this requires a well-conceived
organization and a management hierarchy. In the case of the HGP, there happen
to be two such: the National Human Genome Research Institute (NHGRI) and The
Institute for Genomic Research (TIGR), also known as Celera Genomics. This is a
good thing, because the two organizations provide a cross-check on each other
and thereby greatly diminish the number of sequencing errors. It is by no means
a duplication of effort. Inevitably, however, it also engenders a competitive
atmosphere, particularly for scarce resources. This may or may not be such a
good thing, although so far it has kept things lively and moving right along.
Not surprisingly, both projects are headquartered in the
The heads of these two organizations are Francis S. Collins and J. Craig Venter. Both are staggeringly brilliant but quite different in their approaches to sequencing the Homo sapiens genome. The following two essays profile these two men and tell us something about what inspires them.

The combination of world-class scientific researcher, savvy political activist, federal program chief, and serious Christian, is not often found in one person. Yet that constellation of traits is vigorously expressed in Francis S. Collins. Collins leads the U.S. Human Genome Project, an ambitious effort to analyze the Homo sapiens genetic inheritance in its ultimate molecular detail. A physician by training, he became a scientific superstar in 1989, when he was a researcher at the University...
2. Haemophilus influenzae which can cause meningitis and deafness
J. Craig Venter, the voluble director of the Institute for Genomic Research (TIGR) in Rockville , Md. , is much in demand these days. A tireless self-promoter, Venter set off shock waves in the world of Homo sapiens genetics in May 1998 by announcing, via the front page of the New York Times, a privately funded $300-million, three-year initiative to determine the sequence of almost all the three billion chemical units that make up Homo sapiens DNA, o...
3. Deciphering the Code of Life
When historians look back at this turning of the millennium, they will note that the major scientific breakthrough of the era was the characterization in ultimate detail of the genetic instructions that shape a Homo sapiens being. The Human Genome Projectwhich aims to map every gene and spell out letter by letter the literal thread of life, DNAwill affect just about every branch of biology. The complete DNA sequencing of more and more organisms, including Homo sapienss, will answer many important questions, such as how organisms evolved,...
4. Discovering Genes for New Medicines
Most readers are probably familiar with the idea of a gene as something that transmits inherited traits from one generation to the next. Less well appreciated is that malfunctioning genes are deeply involved in most diseases, not only inherited ones. Cancer, atherosclerosis, osteoporosis, arthritis and Alzheimer’s disease, for example, are all characterized by specific changes in the activities of genes. Even infectious disease usually provokes the activation of identifiable genes in a patient’s immune system. Moreover, ac...
5. How to Make and Separate cDNA Molecules
Cells use messenger RNA to make protein. We discover genes by making complementary DNA (cDNA) copies of messenger RNA. First we have to clone and produce large numbers of copies of each cDNA, so there will be enough to determine its constituent bases. Molecular biologists have developed ways to insert cDNA into specialized DNA loops, called vectors, that can reproduce inside bacterial cells. A mixture of cDNAs from a given tissue is called a library. Researchers at HGS have now prepared Homo sapiens cDNA libraries from almost all n...
6. How to Find a Partial cDNA Sequence
Researchers find partial cDNA sequences by chemically breaking down copies of a cDNA molecule to create an array of fragments that differ in length by one base. In this process, the base at one end of each fragment is attached to one of four fluorescent dyes, the color of the dye depending on the identity of the base in that position. Machines then sort the labeled fragments according to size. Finally, a laser excites the dye labels one by one. The result is a sequence of colors that can be read electronically and that corresponds ...
7. Origin of Species by Means of Natural Selection
The questions we do not yet have the wit to ask will be a growing preoccupation of science in the next 50 years. That is what the record shows. Consider the state of science more than a century ago, in 1899. Then, as now, people were reflecting on the achievements of the previous 100 years. One solid success was the proof by John Dalton in 1808 that matter consists of atoms. Another was the demonstration (by James Prescott Joule in 1851) that energy is indeed conserved and the earlier surmise (by French physicist Sadi Carnot) that the...
8. Several companies have sprouted up to provide bioinformatics tools
Unprecedented fanfare greeted the June 26, 2000 announcement that scientists had completed a draft of the Homo sapiens genome sequence. The truth is, however, that figuring out the order of the letters in our genetic alphabet was the easy part. Now comes the hard part: deciphering the meaning of the genetic instruction article. The next stage goes by a deceptively prosaic name: annotation. Strictly speaking, “annotation” comprises everything that can b...

Correct errors and proofread. The original plan was to repeat the sequencing up to 12 times to prune away the mistakes that inevitably accompany a project involving 3.1 billion pieces of datum. In the rush to make the joint announcement, the privately funded Celera Genomics and the publicly funded international consortium Human Genome Project settled temporarily for le...

If the biotechnology company called Myriad Genetics has its way, thousands of healthy women in the U.S. will hear doubly bad news. First, a close relativeperhaps a sisterwill announce that she has breast cancer. Second, the patient’s physician thinks this particular cancer has probably been caused by a mutation that the healthy relative has an even chance of also carrying. This patient has been advised to suggest to all her female relatives that they be tested for t...
