Gene-edited beagles may offer a future option for people with dog allergies

Scientists at Kindred Companion Sciences have successfully used CRISPR gene editing to create two hypoallergenic beagles, Bailey and Alfie, that do not trigger allergies in individuals like geneticist Matt Walker. The gene editing technique switched off the primary gene responsible for producing allergy-causing proteins in the dogs' saliva and hair. This breakthrough, published in the CRISPR Journal, marks the first successful application of this method in dogs. While it offers a potential future for allergy sufferers to own pets, widespread availability is years away due to the need for long-term health monitoring, commercialization, and affordability. Bioethicists also note potential concerns about discouraging adoption of shelter animals.

Scientists at Kindred Companion Sciences have successfully used CRISPR gene editing to create hypoallergenic beagles, Bailey and Alfie, by switching off the gene responsible for the main allergy-causing protein in dogs. This breakthrough, published in the CRISPR Journal, allows individuals like geneticist Matt Walker, who previously suffered from dog allergies, to interact with the dogs without symptoms. While this development offers hope for millions with pet allergies, it will take years before it's commercially available due to the need for long-term health monitoring and affordability considerations. Experts also note potential concerns about discouraging adoption of shelter animals. The technique has been tested on Walker, whose skin showed no reaction to the gene-edited beagles, unlike other breeds.
