The Canine Genetics Centre (CGC) is excited to announce the launch of a new DNA test through Canine Genetic Testing (CAGT) for Retinopathy with Vitamin E Deficiency (RVED) in Cocker Spaniels. Our discovery, made in collaboration with leading veterinary ophthalmologists, could have significant health implications for Cocker Spaniels, and not only those born in the future but potentially some that are alive today.
Previously, diagnosing RVED required an examination by a veterinary ophthalmologist, which involved identifying characteristic pigmented spots on the retina, followed by a blood test to confirm low vitamin E levels. And typically the disease would only be diagnosed at a relatively late stage of the disease process, when a dog’s vision had started to deteriorate.
Our new DNA test enables early identification of dogs with two copies of the RVED mutation. These dogs will develop retinal disease (and possibly neurological signs) if not treated. But if a vitamin E deficiency is confirmed by a veterinary surgeon, then twice daily oral administration of Vitamin E usually restores levels to the normal range and should halt progression of retinal and brain disease.
The power of DNA testing is usually to ensure the health of future generations of dogs The RVED test is different – it could help maintain the health of dogs that are alive now.
A scientific paper is being prepared that will detail these findings, and a DNA test based on this newly identified mutation is available from Canine Genetics Testing. Take the proactive step to ensure your Cocker Spaniel’s health today!
