Abstract
Mendelian forms of photoreceptor degeneration arise from mutation of any one of hundreds of different genes. We hypothesize that these diverse proximate causes converge on a limited number of deleterious cellular pathways. If so, interdicting one or more of these pathways could provide a more general approach to slowing photoreceptor degeneration, as compared to therapies aimed at replacement of individual defective genes. We have devised a strategy to identify loss of function mutations that slow photoreceptor degeneration in a mouse model of retinitis pigmentosa. We will report our progress toward achieving the goal of performing a global screen in live mice.
