RORA and Stargardt disease: AAV-based systems have also been used to deliver other gene products with potential for STGD1 intervention including vMCO-I (vMCO-010) [37], which confers photosensitivity to the inner retina bypassing degenerated photoreceptors in end-stage Stargardt disease, and RORA (OCU-410ST) [34], which supports photoreceptor function and homeostasis.
