What is the RPE65 gene responsible for?
What is the RPE65 gene responsible for?
The RPE65 gene provides instructions for making a protein that is essential for normal vision. The RPE65 protein is produced in a thin layer of cells at the back of the eye called the retinal pigment epithelium (RPE).
What protein is RPE65?
Retinal pigment epithelium-specific 65 kDa protein, also known as retinoid isomerohydrolase, is an enzyme of the vertebrate visual cycle that is encoded in humans by the RPE65 gene….

What is Biallelic RPE65 mutation associated retinal dystrophy?
Individuals with biallelic RPE65 mutation-associated retinal dystrophy experience progressive deterioration of vision over time. This loss of vision, often during childhood or adolescence, ultimately progresses to complete blindness.
What chromosome is RPE65 on?
In 1994, the RPE65 gene was mapped to human chromosome 1 (mouse chromosome 3), and was refined to 1p31 by fluorescence in situ hybridization5,8. In 1995, Nicoletti et al. described the human gene structure5. The RPE65 gene contains 14 coding exons5,8 spanning 20 kb and encodes a protein of 533 amino acids5,8–10.
Is Luxturna FDA approved?
In 2017, the US Food and Drug Administration (FDA) approved voretigene neparvovec-rzyl (Luxturna), a gene therapy used to treat a rare form of inherited blindness.
How many people have RPE65 mutation?
It is estimated that between 1,000 and 2,000 individuals in the United States have RPE65-related inherited retinal dystrophy (RPE65-IRD), which includes RPE65-LCA/EOSRD and typical retinitis pigmentosa (RP type 20) [Lloyd et al 2019] (see Genetically Related Disorders).
Is Luxturna permanent?
LUXTURNA has demonstrated sustained efficacy Improvements in functional vision have been sustained for 4 years—with observations ongoing. Follow-up will continue for up to 15 years postadministration.
Is Luxturna a T car?
They’re known as CAR-T therapies. Luxturna is the first of a crop of treatments that target diseases caused by mutations in specific genes, and thus is referred to by many as the first gene therapy in the U.S.
What is the disadvantage of Luxturna?
One major disadvantage of Luxturna is its severely limited therapeutic target, since it is effective only for the 1,000 to 2,000 patients in the United States with the recessive RPE65 mutation. Many more thousands of patients suffering from hereditary retinal degenerative disease do not yet have a viable gene therapy.
Is spark Therapeutics publicly traded?
