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-PRA 1 usually appears at the age of 6 and leads to vision loss and blindness. It is inherited in an autosomal recessive manner. To date, 3 different mutations that cause PRA have been discovered in Golden Retriever dogs, namely PRA-PRCD, GR-PRA1 and GR-PRA2, of which GR-PRA1 is responsible for more than 60% of all diagnosed cases of PRA.
