All of Us Research Program Participants Fuel Both Scientific and Personal Discovery
Posted on by Josh Denny, M.D., M.S., All of Us Research Program
The NIH’s All of Us Research Program is a historic effort to create an unprecedented research resource that will speed biomedical breakthroughs, transform medicine and advance health equity. To create this resource, we are enrolling at least 1 million people who reflect the diversity of the United States.
At the program’s outset, we promised to make research a two-way street by returning health information to our participant partners. We are now delivering on that promise. We are returning personalized health-related DNA reports to participants who choose to receive them.
That includes me. I signed up to receive my “Medicine and Your DNA” and “Hereditary Disease Risk” reports along with nearly 200,000 other participant partners. I recently read my results, and they hit home, revealing an eye-opening connection between my personal and professional lives.
First, the professional. Before coming to All of Us, I was a practicing physician and researcher at Vanderbilt University, Nashville, TN, where I studied how a person’s genes might affect his or her response to medications. One of the drug-gene interactions that I found most interesting is related to clopidogrel, a drug commonly prescribed to keep arteries open after a major cardiovascular event, like a heart attack, stroke, or placement of a stent.
People with certain gene variations are not able to process this medication well, leaving them in a potentially risky situation. The patient and their health care provider may think the condition is being managed. But, since they can’t process the medication, the patient’s symptoms and risks are likely to increase.
The impact on patients has been seen in numerous studies, including one that I published with colleagues last year in the Journal of Stroke and Cerebrovascular Disease [1]. We found that stroke risk is three times higher in patients who were poor responders to clopidogrel and treated with the drug following a “mini-stroke”—also known as a transient ischemic attack. Other studies have shown that major cardiovascular events were 50 percent more common in individuals who were poor responders to clopidogrel [2]. Importantly, there are alternative therapies that work well for people with this genetic variant.
Now, the personal. Reading my health-related results, I learned that I carry some of these very same gene variations. So, if I ever needed a medicine to manage my risk of blood clots, clopidogrel would not likely work well for me.
Instead, should I ever need treatment, my provider and I could bypass this common first-line therapy and choose an alternate medicine. Getting the right treatment on the first try could cut my chances of a heart attack in half. The benefits of this knowledge don’t stop with me. By choosing to share my findings with family members who may have inherited the same genetic variations, they can discuss it with their health care teams.
Other program participants who choose to receive results will experience the same process of learning more about their health. Nearly all will get actionable information about how their body may process certain medications. A small percentage, 2 to 3 percent, may learn they’re at higher risk of developing several severe hereditary health conditions, such as certain preventable heart diseases and cancers. The program will provide a genetic counselor at no cost to all participants to discuss their results.
To enroll participants who reflect the country’s diverse population, All of Us partners with trusted community organizations around the country. Inclusion is vitally important in the field of genomics research, where available data have long originated mostly from people of European ancestry. In contrast, about 50 percent of the All of Us’ genomic data come from individuals who self-identify with a racial or ethnic minority group.
More than 3,600 research projects are already underway using data contributed by participants from diverse backgrounds. What’s especially exciting about this “ecosystem” of discovery between participants and researchers is that, by contributing their data, participants are helping researchers decode what our DNA is telling us about health across all types of conditions. In turn, those discoveries will deepen what participants can learn.
Those who have stepped up to join All of Us are the heartbeat of this historic research effort to advance personalized approaches in medicine. Their contributions are already fueling new discoveries in numerous areas of health.
At the same time, making good on our promises to our participant partners ensures that the knowledge gained doesn’t only accumulate in a database but is delivered back to participants to help advance their own health journeys. If you’re interested in joining All of Us, we welcome you to learn more.

Note: Dr. Lawrence Tabak, who performs the duties of the NIH Director, has asked the heads of NIH’s Institutes, Centers, and Offices to contribute occasional guest posts to the blog to highlight some of the interesting science that they support and conduct. This is the 24th in the series of NIH guest posts that will run until a new permanent NIH director is in place.
All of Us: Partnering Together for the Future of Precision Medicine
Posted on by Dr. Francis Collins
Over the past year, it’s been so inspiring to watch tens of thousands of people across the country selflessly step forward for vaccine trials and other research studies to combat COVID-19. And they are not alone. Many generous folks are volunteering to take part in other types of NIH-funded research that will improve health all across the spectrum, including the more than 360,000 who’ve already enrolled in the pioneering All of Us Research Program.
Now in its second year, All of Us is building a research community of 1 million participant partners to help us learn more about how genetics, environment, and lifestyle interact to influence disease and affect health. So far, more than 80 percent of participants who have completed all the initial enrollment steps are Black, Latino, rural, or from other communities historically underrepresented in biomedical research.
This community will build a diverse foundation for precision medicine, in which care is tailored to the individual, not the average patient as is now often the case. What’s also paradigm shifting about All of Us is its core value of sharing information back with participants about themselves. It is all done responsibly through each participant’s personal All of Us online account and with an emphasis on protecting privacy.
All of Us participants share their health information in many ways, such as taking part in surveys, offering access to their electronic health records, and providing biosamples (blood, urine, and/or saliva). In fact, researchers recently began genotyping and sequencing the DNA in some of those biosamples, and then returning results from analyses to participants who’ve indicated they’d like to receive such information. This first phase of genotyping DNA analysis will provide insights into their genetic ancestry and four traits, including bitter taste perception and tolerance for lactose.
Results of a second sequencing phase of DNA analysis will likely be ready in the coming year. These personalized reports will give interested participants information about how their bodies are likely to react to certain medications and about whether they face an increased risk of developing certain health conditions, such as some types of cancer or heart disease. To help participants better understand the results, they can make a phone appointment with a genetic counselor who is affiliated with the program.
This week, I had the pleasure of delivering the keynote address at the All of Us Virtual Face-to-Face. This lively meeting was attended by a consortium of more than 2,000 All of Us senior staff, program leads with participating healthcare provider organizations and federally qualified health centers, All of Us-supported researchers, community partners, and the all-important participant ambassadors.
If you are interested in becoming part of the All of Us community, I welcome you—there’s plenty of time to get involved! To learn more, just go to Join All of Us.

My blog usually celebrates biomedical advances made possible by NIH-supported research. But every August, I like to try something different and highlight an aspect of the scientific world that might not make headlines. This year, I’d like to take a moment to pay tribute to just a few of the many NIH family members around the country who, without pay or fanfare, freely give of themselves to make a difference in their communities.
I’d like to start by recognizing my wife Diane Baker, a genetic counselor who has always found time during her busy career to volunteer. When I was first being considered as NIH director, we had lots of kitchen table discussions about what it might mean for us as a couple. We decided to approach the position as a partnership. Diane immediately embraced the NIH community and, true to her giving spirit, now contributes to some wonderful charities that lend a welcome hand to patients and their loved ones who come to the NIH Clinical Center here in Bethesda, MD.

When most of us come down with a bacterial infection, we generally bounce back with appropriate treatment in a matter of days. But that’s often not the case for people who suffer from common variable immunodeficiency (CVID), a group of rare disorders that increase the risk of life-threatening bacterial infections of the lungs, sinuses, and intestines. CVID symptoms typically arise in adulthood and often take many years to diagnose and treat, in part because its exact molecular causes are unknown in most individuals.
Now, by combining the latest in genomic technology with some good, old-fashioned medical detective work, NIH-funded researchers have pinpointed the genetic mutation responsible for an inherited subtype of CVID characterized by the loss of immune cells essential to the normal production of antibodies [1]. This discovery, reported recently in The New England Journal of Medicine, makes it possible at long last to provide a definitive diagnosis for people with this CVID subtype, paving the way for them to receive more precise medical treatment and care. More broadly, the new study demonstrates the power of precision medicine approaches to help the estimated 25 to 30 million Americans who live with rare diseases [2].
