Disease Focus
GenSight Biologics currently focuses on severe inherited neurodegenerative diseases of the eye that cause blindness and have limited treatment options.
Leber Hereditary Optic Neuropathy (LHON)
LHON is the world’s most prevalent mitochondrial disease and an important cause of inherited blindness in young adults. Resulting from inherited mitochondrial DNA mutations, LHON causes sudden, usually irreversible vision loss, profoundly impacting a patient’s autonomy and quality of life.
Retinitis Pigmentosa (RP)
RP is the world’s most prevalent inherited retinal disease and a leading cause of visual disability and blindness, often beginning in childhood or adolescence. Resulting from diverse inherited genetic mutations, RP causes progressive, irreversible vision loss, profoundly impacting a patient’s autonomy and quality of life.
