New NIH/NHGRI grants to harness nanoscale technologies to cut DNA sequencing costs
Date:9/14/2012

Grants of almost $19 million will help to develop technologies to dramatically reduce the cost of DNA sequencing, the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, announced today.

During the past decade, DNA sequencing costs have fallen dramatically (see www.genome.gov/sequencingcosts), fueled by tools, technologies and process improvements developed by genomics researchers. In 2004, NHGRI launched the Advanced DNA Sequencing Technology Program to accelerate improvements in DNA sequencing technologies. By 2009, the program had 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 base pairs from each of their parents for $100,000 each. Today, the cost of sequencing a human genome using these next-generation DNA sequencing technologies has dipped to just under $8,000.

Price is one hurdle in the way of widespread use of genomics in research and clinical care. Speed and accuracy are among other factors. The grants will attempt to address all of these challenges.

"We can now access data we could not dream of getting in 2004 when we started this program tens of thousands of human genome sequences have been generated," said Eric D. Green, M.D., Ph.D., NHGRI director. "And yet, the information we would truly like to get for understanding disease and, eventually, for treating patients, requires much better quality sequence data. That is the direction we would like to go with these grants."

The use of nanoscale devices for sequencing, reflected in many of these projects, is accelerating. To say that nanoscale devices function on a very small scale is an understatement. A human hair is 100,000 nanometers in diameter and a single strand of DNA is 2 nanometers in diameter.
