Progressive retinal atrophy (PRA) in dogs is a group of genetically heterogeneous inherited retinal disorders characterized by progressive degeneration and cell death of photoreceptors. GR-PRA1 is a late onset disease (usually at 6 - 7 year) with some individual variation in age of onset, and is inherited in an autosomal recessive manner. Until now, three different mutations were found to cause progressive retinal atrophy (PRA) in Golden Retriever breed: PRA-PRCD, GR-PRA1 and GR-PRA2.

Mutation: SLC4A3 gene
Genetic test: Disease or carrier can be identified by genetic testing at any age. The PCR method used for testing is extremely accurate and allows complete differentiation between affected animals, carriers and healthy dogs.
