X-Linked Progressive Retinal Atrophy Type 1
X-linked progressive retinal atrophy type 1 is a degenerative eye disease that affects Samoyed and Siberian Husky dogs. It occurs due to a mutation in the RPGR gene. The condition causes degeneration of the rods and cones in a dog’s retina. Because this is an X-linked condition, female dogs must inherit two copies of the disease to be affected, while male dogs only need to inherit one.
