Details about the disease
Generalised progressive retinal atrophy (gPRA) is a disease of the retina. This tissue, located inside the back of the eye, contains specialised cells called photoreceptors that absorb the light focused on them by the eye’s lens, and converts this light into electrical nerve signals which are then interpreted by the brain as vision. These photoreceptors are divided into two groups; the cones which aid bright light and colour vision, and the rods which facilitate low light or night vision.
Clinical signs
Affected pups begin showing signs of night-blindness by 6 weeks of age, and by 1-2 years of age most affected dogs are completely blind.
How is it inherited?
The disease is described as an autosomal recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.
Which laboratories test for this condition?
Two lists of laboratories that test for PRA (rcd1) can be found below.
