Breakthrough in Equine Genetics: Researchers Identify Genes Linked to ‘Roaring’ Disorder in Thoroughbreds
In a groundbreaking revelation, researchers at University College Dublin (UCD) and Equinome have identified genetic markers associated with Recurrent Laryngeal Neuropathy (RLN), a debilitating condition affecting up to 18% of Thoroughbred racehorses. Frequently enough referred to as laryngeal hemiplegia or ‘roaring,’ RLN significantly impacts equine performance by impairing upper airway function, leading to reduced airflow and increased breathing effort during exercise.
The study, funded by Research Ireland and conducted in collaboration with a world-leading Thoroughbred training yard, examined over 200 horses-in-training. Researchers employed gold-standard diagnostic methods, including resting and overground exercising upper airway endoscopy, as well as laryngeal ultrasounds, to accurately identify RLN cases.
Using advanced DNA technologies, the team pinpointed a set of genetic markers linked to the disorder. This discovery paves the way for the development of a genetic test capable of identifying horses with a three-times higher risk of developing RLN.“Accurately diagnosing disease using gold-standard methodologies is one of the most meaningful factors in a genetic study,” said project lead Lisa Katz,UCD Professor in Equine Internal Medicine. “Following years of intensive veterinary examination of the horses, it is extremely rewarding to see our research come to fruition.”
Katz emphasized the practical implications of the findings: “Understanding the genetic risk of your horse for roaring can definitely help with early intervention and management. This might include monitoring highly predisposed horses more closely and considering surgical interventions at an earlier stage to improve treatment success.”
The research, published in the peer-reviewed Equine Veterinary Journal, marks a significant step forward in equine health. By enabling early detection and targeted management strategies, this breakthrough could transform the way RLN is addressed in the racing industry.

As the racing industry continues to prioritize equine welfare, this discovery offers hope for improved health outcomes and enhanced performance for Thoroughbreds worldwide.Groundbreaking Research Sheds Light on Roaring Horse Disorder
A team of researchers lead by Emmeline Hill at University College Dublin has unveiled new findings on Recurrent Laryngeal Neuropathy (RLN), commonly known as roaring horse disorder. This condition, which affects the upper airway in horses, has long puzzled veterinarians and breeders. The study, published recently, offers fresh insights into the genetic and physiological mechanisms behind the disorder, perhaps paving the way for improved diagnostics and treatments.
What is Roaring Horse Disorder?
Roaring horse disorder, or laryngeal hemiplegia, is a condition where one or both of the arytenoid cartilages in a horse’s larynx fail to function properly. This leads to a partial or complete paralysis of the vocal cords, causing a distinctive “roaring” sound during exercise. The disorder can severely impact a horse’s performance, especially in racing and other high-intensity activities.
According to Lisa Katz, a co-author of the study, “This research is a significant step forward in understanding the genetic underpinnings of RLN. It opens up new possibilities for early detection and targeted interventions.”
Key findings from the Study
The research team identified specific genetic markers associated with Recurrent Laryngeal Neuropathy, shedding light on why certain horses are more susceptible to the condition. By analyzing DNA samples from affected and unaffected horses, the team discovered variations in genes linked to nerve function and muscle development.
“Our findings suggest that RLN is not just a random occurrence but has a strong genetic component,” said Emmeline Hill. “This could revolutionize how we approach breeding and managing horses prone to this disorder.”
The study also highlighted the importance of early diagnosis. Horses with mild symptoms often go undetected until the condition progresses, leading to irreversible damage. with this new genetic insight, breeders and veterinarians may soon be able to identify at-risk horses before symptoms appear.
Implications for the Equine Industry
The equine industry, particularly in Europe, stands to benefit significantly from this research. Roaring horse disorder is a major concern for thoroughbred breeders, as it can diminish a horse’s value and performance. By incorporating genetic testing into breeding programs, breeders can reduce the prevalence of RLN and produce healthier, more competitive horses.

What’s Next?
The research team plans to expand their study to include a larger sample size and explore potential treatments. “We’re just scratching the surface,” said Lisa Katz. “There’s still much to learn about how these genetic factors interact with environmental influences.”
For horse owners and breeders, this study underscores the importance of staying informed about advancements in equine health. By leveraging genetic testing and early intervention strategies, the industry can mitigate the impact of roaring horse disorder and ensure the well-being of these splendid animals.

Groundbreaking Research on Roaring Horse Disorder: A conversation with Geneticist Emmeline Hill
In a recent breakthrough study, researchers from University College Dublin have identified genetic markers linked to Recurrent Laryngeal Neuropathy (RLN), commonly known as roaring horse disorder. This condition, which affects up to 18% of Thoroughbred racehorses, impairs upper airway function, leading to reduced performance and a distinctive “roaring” sound during exercise. To delve deeper into these findings, we sat down with Dr. Emmeline Hill, a leading geneticist and co-author of the study, to discuss the implications of this groundbreaking research.
Understanding Roaring Horse Disorder
Senior Editor: Dr. Hill, thank you for joining us today. To start, can you explain what roaring horse disorder is and why it’s such a critical issue for the equine industry?
Dr. Emmeline Hill: Absolutely. Roaring horse disorder, or RLN, is a condition where the arytenoid cartilages in a horse’s larynx fail to function properly. This results in partial or complete paralysis of the vocal cords, leading to reduced airflow and a distinctive roaring sound during exercise. it’s particularly problematic for racehorses, as it can severely impact their performance and welfare.
The Genetic Breakthrough
Senior Editor: Your study has identified genetic markers associated with RLN. Can you walk us through the key findings and their significance?
Dr. Emmeline Hill: Certainly. We analyzed DNA samples from over 200 Thoroughbreds and identified specific genetic variations linked to nerve function and muscle progress. These markers are strongly associated with RLN,suggesting a important genetic component to the disorder. This discovery is a game-changer because it allows us to develop a genetic test that can identify horses at a three-times higher risk of developing RLN.
Implications for breeders and Veterinarians
