Brand names: LUXTURNA
12.1 Mechanism of Action LUXTURNA is designed to deliver a normal copy of the gene encoding the human retinoid isomerohydrolase RPE65 (RPE65) to cells of the retina in persons with reduced or absent levels of biologically active RPE65. The RPE65 is produced in the retinal pigment epithelial (RPE) cells and converts all- trans -retinol to 11- cis -retinol, which subsequently forms the chromophore, 11- cis -retinal, during the visual (retinoid) cycle. The visual cycle is critical in phototransduction, which refers to the biological conversion of a photon of light into an electrical signal in the retina. Mutations in the RPE65 gene lead to reduced or absent levels of retinoid isomerohydrolase RPE65 activity, blocking the visual cycle and resulting in impairment of vision.
