The AHT do some excellent work. As well as the above, they also do the following, copied from their website:

Hereditary Cataract & Progressive Retinal Atrophy
Funded by the Kennel Club Charitable Trust the canine genetics team are now involved in an exciting project to study the genetics of Hereditary Cataract (HC) and Progressive Retinal Atrophy (PRA) in the Golden Retriever, the American Cocker Spaniel and the Tibetan Spaniel.

We aim to identify the genetic mutations that are responsible for HC in the Golden Retriever and the American Cocker Spaniel and for PRA in the Golden Retriever and the Tibetan Spaniel. We will develop DNA diagnostic tests that breeders can use to eliminate these debilitating diseases from their breeds.

In addition to the 3 breeds listed above we are also investigating the genetics of HC in Australian Shepherds, Siberian Huskies, Large Munsterlanders and any other breeds for which we can collect sufficient DNA samples.

The success of this research will largely depend on the successful collection of DNA from dogs that can usefully contribute to our research. All research is carried out in the strictest confidence and we do not share genetic information about any dog with anybody except that dog’s owner.
