Short description

Progressive Retinal Atrophy (PRA) is a large group of genetic diseases in which the retina gradually degenerates over time, causing a progressive loss of vision.

General information

Progressive Retinal Atrophy (PRA) is a large group of genetic diseases in which the retina gradually degenerates over time, causing a progressive loss of vision. The specific variant of the disorder analysed in this test, Rod–Cone Dysplasia (rdy-PRA) causes a rare form of early-onset blindness.

rdy-PRA in cats is caused by a dominant mutation to the gene CRX. It has been observed in the Abyssinian, Somali and Savannah breeds.
