In this condition the rods are initially more affected than the cones giving problems with night blindness (nyctalopia). Cones typically break down before rods, which is why sensitivity to light and impaired color vision are usually the first signs of the disorder. The early-stage. Changes in at least two genes cause the X-linked form of the disorder, which is rare. are responsible for providing instructions to create proteins that are necessary for the healthy development and functioning of retinal cells.
