Description: Progressive retinal atrophy (PRA) is a hereditary disease that occurs in many dog breeds and manifests in various clinically unrecognizable forms. The progressive degeneration of the rods and cones in the retina leads to a progressive loss of vision, which results in complete blindness. RCD4 is a form of PRA that was first described by Gordon Setters and later found in several other dog breeds. Gradual degeneration of photoreceptor cells is typical. The mean age of onset is 10 years, cases were observed at the age of 5 to 12 years.

Mutation: c.3149_3150insC in C2orf71 gene
