The advent of whole genome sequencing technology has prompted an explosion in research into how genetics are associated with disease risk. But the vast majority of genetics research has been done on people of European ancestry, and genetics researchers have realized that in order to address health disparities, more needs to be done.

In a new study, Georgia Tech researchers investigated whether 25 rare gene variants known to be associated with inflammatory bowel disease (IBD) play a role in risk for African Americans. While the rare variant associations were recently discovered in individuals of European ancestry, contributing to about 15% of cases, it was unknown if and how those same rare gene variants might affect risk for African Americans.

Led by Greg Gibson, Regents’ Professor and Tom and Marie Patton Chair in the School of Biological Sciences, the study highlights the importance of considering genetic diversity and the mixing of ancestry in genetics research. The findings were published in the journal Genome Medicine.

“Because of major advancements in the last decade, we now know that most diseases are far more complex than we originally thought, in terms of genetics,” said Gibson, who is also director of the Center for Integrative Genomics at Georgia Tech. “Understanding whether genetic differences contribute to health disparities is a major point of focus for current genetics research, and we had an opportunity to test one idea with this study.”

Today, African Americans have a similar prevalence of various types of IBD as European Americans. But progression is often much worse: African Americans are more likely to progress to severe disease requiring colectomies and other major interventions.

Courtney Astore, a Ph.D. student in Gibson’s lab and first author on the paper, wanted to assess whether those same rare variants would have a similar effect on IBD risk in African Americans. In a collaboration with Subra Kugathasan from Emory University and the NIH’s IBD Genetics Consortium, Gibson’s lab had analyzed the complete genome sequences of over 3,000 genomes of African Americans, half with IBD. Astore used that database to conduct her analysis.  

She started by plotting the difference in frequency of the rare variants, and quickly realized that there was a significant reduction in prevalence of the variants in African Americans. Through further computations, she estimated that European ancestry variants actually only made a very small contribution to IBD in African Americans (around 44 additional cases per 100,000 people), fourfold less than Americans of European ancestry.

“Prior to our analysis, we suspected that admixture may play a role in the presence of IBD-associated rare variants in African Americans,” Astore said. “When I saw the differences, that was when I realized that there was something important there that we needed to discover.”

Astore then used a method known as chromosome painting, which is a tool for visualizing where each segment of the genome comes from. She showed that the rare variants found in African Americans were almost always located on segments of European ancestry genomes.

In simple terms, the location of the variants indicated that the genes resulted from admixture — a scientific term for mixing of genetic backgrounds throughout ancestry — which enabled Astore to show that the mutations had arisen outside of Africa, and only began to appear in people of African ancestry over the last dozen generations.

To conclude the study, Gibson and Astore assessed the presence of other rare variants associated with a dozen other diseases, which similarly confirmed that the presence of the variants contributes to African Americans generally through admixture.

The findings are important for several reasons. First, they highlight the value of considering genetic diversity and admixture in all genetics research, and especially when investigating rare variants and their associations with complex disease. While they showed that the European variants were rare in African Americans, there are almost certainly rare variants that contribute to IBD in African Americans that have yet to be discovered and may point to biological mechanisms.

“Doing more genetic studies on diverse populations, and especially those that have admixture, is going to be pivotal for therapeutic discovery,” Astore said.

Precision medicine will eventually be tailored to a person’s genome, which means that in some cases knowing the identity of rare variants will help guide therapy. If that is the case, knowing the context of ancestry will be beneficial. It also means that if more research on diverse ancestry groups isn’t done, then new treatments might not be effective for all people. The team also emphasizes that genetics is not the only factor contributing to risk for complex diseases like IBD, and their study simply highlights that it cannot be assumed that genetic discoveries are risk factors for all people.  

“Our study emphasizes that in order to move in the direction of greater health equity, it is absolutely crucial to do large-scale genetic sequencing for African Americans and all ancestry groups,” Gibson said. “We hope our work will encourage more research on both social determinants of health and the genetics of IBD across ancestries.”

 

Note: The IBD Genetics Consortium, of which Gibson is a part, organized the cohort of African Americans with IBD, and their samples were gathered at institutes across the country, including Emory University, Johns Hopkins University, Rutgers University, Cedars Sinai Los Angeles, and Mt. Sinai New York.

Hundreds of thousands of honeybees make their home atop The Kendeda Building for Innovative Sustainable Design, and it's up to Janelle Dunlap to make sure the hives thrive.  

Dunlap was hired earlier this year as the Urban Honey Bee Project's (UHBP) first-ever beekeeper in residence. Throughout her residency, she'll conduct research into the pollinator's place in our ecosystem and how beekeeping may offer relief to veterans dealing with post-traumatic stress disorder (PTSD), while connecting with the bees through art.  

Dunlap had been gardening for over a decade, but in 2016, when she got the urge to find new ways to engage with nature, she recalled a powerful piece of imagery that shaped her childhood — Wu-Tang Clan's music video for “Triumph” and its depiction of the group's members as a powerful swarm of Africanized killer bees.  

"The political messaging and tying Africanized killer bees in with the stereotypes and the tropes of African Americans in the media, and the way that that was so poetically tied in, visually stuck with me,” she said. “It was the first time I recognized a political message being articulated through art. For that reason, it stuck with me that bees were a form of strong symbolism tied to resilience." 

Living in Charlotte, North Carolina, Dunlap became a certified beekeeper under the Mecklenburg County Beekeepers Association in 2017. She continued practicing as she moved around the country, with stops in Chicago and Denver, eventually landing in Atlanta in 2021. Looking for a way to connect to the local beekeeping community, she attended an April presentation by UHBP Director Jennifer Leavey, who offered Dunlap a chance to get involved at Georgia Tech.  

She now handles the inspection of the hives on The Kendeda Building roof, where she monitors for pests and ensures the bees have proper nutrition to sustain their population through the seasons. The UHBP began in 2012 with the goal of educating the Tech community on the importance of these pollinators within the Atlanta ecosystem and beyond — a charge that Dunlap carries on.  

Over the next year, she will continue working on her sound art project that examines the frequency at which bees “buzz” and how it, along with the responsibilities of beekeeping, is being used by VA hospitals and programs to ease the effects of PTSD. While the science behind the connection is still being explored, beekeeping was recommended more than a century ago — to soldiers returning home from World War I — according to a CNBC profile of Bees4Vets, a nonprofit based in Nevada.  

From the Hive to the Canvas 

Whether it was baking sourdough bread or learning a new language, many people, including Dunlap, took the early days of the Covid-19 pandemic to pick up a new hobby. She began a master's program at the School of the Art Institute of Chicago with the goal of using beeswax in encaustic painting, which uses hot wax mixed with pigments. The use of natural materials collected through her beekeeping practice connects Dunlap to her work.  

“It's a way of tapping into another level of consciousness. It's a way of articulating the noncommunicable relationship between me and the bees. When there's a language gap between people, we try to fill it in with translation, but without a direct way to translate the language or the sensation that I feel from the bees, this allows me to document my practice in an abstract form,” she said.  

By layering the wax and applying heat throughout the process, Dunlap watches the pieces take shape, often with the unpredictability of an active hive, as she says the art “can create itself.” She collects the wax in small amounts, knowing that she can only produce her art if the bees are healthy.  

"It's an eco-conscious practice, making sure I don't use more than I need," she explained. “I love the landscape it creates, and it's all about me creating a direct relationship with my medium and knowing that I earned it by developing a relationship with the bees." 

As Dunlap continues her year-long residency with the UHBP, she intends to help educate the community, both on campus and around the Atlanta area, in the hopes that more prospective beekeepers will explore their curiosity to unlock the full potential of the practice. 

"It's been a practice that keeps unveiling itself to me," she said. "As you get more engaged, you learn there is so much more to it than just the day-to-day hive inspections. There is a lot of beauty to it as well." 

Students at Tech have several ways to get involved with research and beekeeping, including the Living Building Science VIP team, the Beekeeping Club, and various classes and workshops hosted by the UHBP

Please join Provost McLaughlin for a virtual town hall on Tues. Oct. 31 from 11 a.m. to noon. The town hall is open to faculty, staff, and students and will offer a few academic updates, as well as a live Q&A session.

Each year, less than 10 members from the APS DFD community receive this elevation and this year only eight Fellows were selected.

“I am humbled to be elected among my teachers and mentors who have taught me everything I know,” said Hu. “I see that I have a responsibility, like the previous generation of fellows, to represent the subject matter well, make the difficult decisions, and help foster the next generation of fluid mechanics, whatever it may look like.”

Georgia Tech and the College of Sciences community sends its condolences to the family and friends of James (Jim) Reedy, a former professor and chair of the College's former Department of Health & Physical Education. His family held a memorial service on October 23 in Atlanta, Georgia.

Philip Sparling, professor emeritus in the School of Biological Sciences, shared the following message in honor of Reedy:

“Dr. Jim Reedy, a longtime department chair at Georgia Tech, passed away on October 4th at age 85. Recruited in 1978, he led major changes in his unit’s mission and curriculum that included an expansion from physical training classes to courses in lifetime fitness, human anatomy, exercise physiology, and biomechanics. He provided resources to new faculty to develop research programs and transformed the Department of Physical Education & Recreation into the Department of Health & Performance Sciences, a unit within the College of Sciences (today as part of the School of Biological Sciences). He served as chair for 20 years under four different deans (1978-1998). He retired in 2000. Dr. Reedy was a charismatic, passionate, and gifted administrator who had a lasting impact on the GT community.”

James Reedy obituary

James Alan Reedy, beloved husband, father, grandfather and friend passed away peacefully on October 4, 2023, in Atlanta, Georgia. He was 85 years old. Born in Clintwood, Virginia, he was preceded in death by his parents Corbett and Lelia Reedy, loving wife Kay Reedy and sister Nancy Olson. He is survived by his children Jody Reedy Andrade (Billy), Betsy Reedy Sawyer (Ryan), Bryan Dunlap (Kelley), Bo Dunlap (Jill), and Greg Kershner (Leigh). Jim was a proud grandfather to his fourteen grandchildren: Cameron, Grace, Tyler, Eli, Sidney, Paige, Grant, Jackson, Meredith, Eliza, Isabella, Sechaba, Talia and Meti. 

Jim was a graduate of John Marshall High School in Richmond, Virginia and Bridgewater College where he resides in the Hall of Fame for men’s basketball. He earned a master’s degree from Long Beach State and doctorate degree from Vanderbilt University. 

Jim had a strong Christian faith grounded from his youth and his parental teachings. This led to a work ethic that was admired for its integrity and dedication to the field of health and physical education. A life-long educator, he served in many roles including teacher, coach, athletic director and college administrator. He began his career at Bridgewater College and finished at Georgia Tech as department head and professor of the Health and Performance Sciences Department. His influence upon those with whom he taught and mentored lingers to this day. 

Jim enjoyed daily exercise, delicious food, a good old movie, anything sports related and especially time with family. He had a gift for storytelling and could captivate an audience with his humorous tales and poems. Over the past several years, he began to write novels and had several published that relied on the connections he had with people throughout his life. He chose joy daily and his encouraging spirit will be forever missed.
