Informations générales
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. This particular variant of PRA, found in the Lapponian Herder, is caused by a recessive mutation to the gene IFT122.
Caractéristiques cliniques
Affected dogs start gradually losing vision in adulthood, presenting with typical ophthalmological signs of PRA such as hyperreflectivity of the retina. Past 9 years of age, PRA becomes more apparent, and may result in total blindness.
