The National Institutes of Health plans to spend $161.3 million over the next five years to expand the Pharmacogenomics Research Network (PGRN), a nationwide collaborative of scientists focused on understanding how genes affect a person’s response to medicines.

“Thanks to breakthroughs in genome sequencing technologies and our growing understanding of genetic variation among individuals, there has never been a better time to propel the field of pharmacogenomics,” said NIH Director Francis S. Collins, M.D., Ph.D. “Through these studies, we are moving closer to the goal of using genetic information to help prescribe the safest, most effective medicine for each patient.”
