Progressive Retinaatrophie (PRA-BBS4)

Progressive retinal atrophy is the most common cause of hereditary blindness in dogs. Bardet - Biedl Syndrome 4 (PRA-BBS4) is an inherited recessive ciliopathy described in Puli. BBS4 is one of eight evolutionary proteins, which are essential to cilia on multiple cell types. The symptoms of disease manifest due to disruptions in ciliary growth maintenance and/or function. Progressive retinal atrophy (PRA-BBS4) is characterized by gradual vision loss, because of degeneration of photoreceptor cells in the retina. The degeneration continues until the affected dogs are completely blind. Other symptoms, when the retina deteriorates, include tapetal hyperreflectivity, vascular attenuation, pigmentary changes and atrophy of the optic nerve head.
