Details about the disease
Progressive retinal atrophy (PRA) is an inherited condition that several breeds of dog are predisposed to. The condition is characterised by bilateral degeneration of the retina, causing progressive vision loss that culminates in total blindness. There is no treatment for PRA, of which several genetically distinct forms are recognised, each caused by a different mutation in a specific gene.
Vision loss and eventual blindness.
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.
