NHGRI funds development of revolutionary DNA sequencing technologies
NIH-supported work to bolster use of genomic tools in research and medicine.
Researchers today received more than $14 million in grants to develop DNA sequencing technologies that will rapidly sequence a person’s genome for $1000 or less. The National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, awarded the grants to enable the everyday use of DNA sequencing technologies by biomedical researchers and health care providers.
“We are confident that NHGRI grantees will continue to make major breakthroughs in the development of technologies that will eventually lead to the ability to sequence a human genome for $1,000 or less,” said NHGRI Director Eric D. Green, M.D, Ph.D. “As genome sequencing costs continue to decline, researchers and clinicians can increase the scale and scope of their studies. We will continue to fund innovative research to accelerate what is known about the genomic basis of human health and disease.”
During the past decade, DNA sequencing costs have fallen dramatically (see http://genome.gov/sequencingcosts for information on what costs are included in producing a high-quality genome). This has been fueled in large part by tools, technologies and process improvements developed by genomic researchers. In 2004, NHGRI launched programs to accelerate improvements in DNA sequencing technologies and to drive down the cost. In 2009, the program surpassed its initial goal of producing high-quality genome sequences of roughly 6 billion base pairs — the amount of DNA found in humans and other mammals that receive roughly 3 billion bases from each of their parents — for $100,000. Today, the cost to sequence a human genome using ‘next-generation’ DNA sequencing technologies has dipped below $20,000.
“With advances in a ‘third generation’ of DNA sequencing technologies, we’re moving closer to the point when researchers and health care providers can routinely and rapidly screen a person’s, or large numbers of people’s, genome using devices that produce highly accurate data,” said Jeffery Schloss, Ph.D., NHGRI's program director for technology development.
The new grants fund nine teams to develop revolutionary technologies that can meet the $1,000 per human genome sequence goal. The approaches will integrate biochemistry, chemistry and physics with engineering to develop the third generation of DNA sequencing and analysis technologies.
