One of the most common effects is the breakdown of rods (cells that detect dim light) and cones (cells that detect light and colour.)
This cause your eyes not to adjust to darkness. Over time it also results in tunnel vision.

Retinitis pigmentosa affects several different genes not just one. The genes it effects are on the X chromosome.
