MYO7A and retinal degeneration: Such studies may be possible using vectors that restrict MYO7A expression to either RPE or photoreceptor cells [30] and this would be useful for elucidating whether functional complementation via myosin VIIa expression directed specifically to either cell compartment is sufficient to rescue α-transducin translocation thresholds and light dependent retinal degeneration in shaker1 mice.
