NHGRI's near-term goal is to lower the cost of sequencing a mammalian-sized genome to $100,000, which would enable researchers to sequence the genomes of hundreds or even thousands of people as part of studies to identify genes that contribute to cancer, diabetes and other common diseases. Ultimately, NHGRI's vision is to cut the cost of whole-genome sequencing to $1,000 or less, which would enable the sequencing of individual genomes as part of medical care. The ability to sequence each person's genome cost-effectively could give rise to more individualized strategies for diagnosing, treating and preventing disease. Such information could enable doctors to tailor therapies to each person's unique genetic profile.
DNA sequencing costs have fallen more than 100-fold over the past decade, fueled in large part by tools, technologies and process improvements developed as part of the successful effort to sequence the human genome. However, it still costs at least $10 million to sequence 3 billion base pairs the amount of DNA found in the genomes of humans and other mammals.
"These grants will open the door to the next generation of sequencing technologies. There are still many opportunities to reduce the cost and increase the throughput of DNA sequencing, as well as to develop smaller, faster sequencing technologies that meet a wider range of needs," said NHGRI Director Francis S. Collins, M.D., Ph.D. "Dramatic reductions in sequencing costs will lead to very different approaches to biomedical research and, eventually, will revolution
