Detailed description
The progressive retinal athrophy (PRA) is an inherited eye disorder leading to a degeneration of the photoreceptor cells of the retina. Initially,a loss of function of the rod cells is observed proceeding in night blindness and decreased adaptation of vision. The PRA form which can be explained by the investigated mutation has an onset of about 5 years. The known genetic variant does not explain all PRA cases. So, one assumes that at least one further mutation is involved in PRA genesis.
