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.
