Progressive retinal atrophy (GR-PRA1)

Progressive retinal atrophy (GR-PRA1)is a hereditary disease which can be tested with a DNA test. 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.

Inheritance: autosomal recessiveread more

Mutation:  SLC4A3  gene

Genetic test: The method used for genetic testing is extremely accurate and allows complete differentiation between affected animals, carriers and healthy dogs. DNA testing can be done at any age.
