DNA test - PRA (rcd3)
Progressive retinal atrophy - rcd3
Welsh Corgi (Cardigan)
Details about the disease
PRA-rcd3 (Progressive Retinal Atrophy rod-cone degeneration 3) is an early-onset PRA mutation that causes bilateral degeneration of the retina which causes progressive vision loss, and eventually blindness.
Puppies may show signs of night-blindness by 6 weeks of age. By the age of 1-2 years most affected dogs are completely blind
How it is inherited
The disease is unique to Welsh Corgis (Cardigan) and 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.
