BECN1 and retinal degeneration: Mice deficient in key components of autophagy (Beclin 1 and Atg7) develop severe retinal degeneration upon light exposure19 and bi‐allelic mutations in the autophagy regulator DRAM2 result in development of retinal degeneration with early macular cone photoreceptor involvement, suggesting an important role for autophagy in retinal homeostasis and function.20
