The Future Written in Genetics

We were excited to learn that, in addition to comprehensive genetic screening through Embark and UC Davis, North Carolina State University has developed a new DNA test for a genetic variant associated with hypertrophic cardiomyopathy (HCM) in Golden Retrievers.

Hypertrophic cardiomyopathy, or HCM, is a serious heart disease in which the muscular wall of the heart becomes abnormally thickened. As the disease progresses, the heart becomes less efficient at pumping blood, and affected dogs may develop heart failure, life-threatening heart rhythm abnormalities, or experience sudden death, sometimes at a very young age.

We were pleased to learn that Lilikoi tested negative for this newly identified genetic variant.

Because this is a relatively new test, it is not yet included in many routine genetic screening panels. As new discoveries emerge, however, they become valuable tools that allow breeders to better understand inherited disease and make more informed breeding decisions.

One of the most exciting aspects of modern canine genetics is the ability to identify direct links between specific genes and inherited diseases. While family history, phenotype, and traditional health clearances remain incredibly important, DNA testing provides another layer of understanding. As researchers continue to uncover the genetic basis of disease, breeders are better equipped to make informed decisions that benefit future generations of dogs.

We are incredibly grateful to the scientists and veterinary researchers whose dedication continues to expand our understanding of canine health. Their work gives breeders valuable tools to protect the future of our breed, and we are thankful that this newly identified HCM-associated genetic variant is not part of our breeding program.

Every discovery brings us one step closer to a healthier future for the Golden Retriever.
