Gene scan helps identify cause of inherited blindness

Scientists at Washington University School of Medicine in St. Louis have scanned the entire genome of mice for genes that help build photoreceptors, the light-sensing cells of the eye. The results have already helped researchers identify the gene that causes a form of retinitis pigmentosa, a type of inherited blindness in humans.
