PRA (rcd 1)

Irish setter progressive retinal atrophy is an inherited disease that leads to blindness in affected dogs. The disease is an early onset form of PRA, and affected dogs are often completely blind by one year of age. It is inherited in a simple autosomal recessive fashion. That is, the disease is not related to the sex of the animal and it requires that both copies of the culprit gene be mutant. The disease in Irish setters was first described in the scientific literature in 1949, although its existence was known much earlier than this.
