متن کاملPupillometric analysis for assessment of gene therapy in Leber Congenital Amaurosis patients
BACKGROUND Objective techniques to assess the amelioration of vision in patients with impaired visual function are needed to standardize efficacy assessment in gene therapy trials for ocular diseases. Pupillometry has been investigated in several diseases in order to provide objective information about the visual reflex pathway and has been adopted to quantify visual impairment in patients with...
متن کاملHuman retinal gene therapy for Leber congenital amaurosis shows advancing retinal degeneration despite enduring visual improvement.
Leber congenital amaurosis (LCA) associated with retinal pigment epithelium-specific protein 65 kDa (RPE65) mutations is a severe hereditary blindness resulting from both dysfunction and degeneration of photoreceptors. Clinical trials with gene augmentation therapy have shown partial reversal of the dysfunction, but the effects on the degeneration are not known. We evaluated the consequences of...
متن کاملMolecular genetics of Leber congenital amaurosis.
Leber congenital amaurosis (LCA) is the most common inherited cause of blindness in childhood and is characterised by a severe retinal dystrophy before the age of one year. Six genes have been identified that together account for approximately half of all LCA patients. These genes are expressed preferentially in the retina or the retinal pigment epithelium. Their putative functions are quite di...
متن کاملDifferential Proteomics and Functional Research following Gene Therapy in a Mouse Model of Leber Congenital Amaurosis
Leber congenital amaurosis (LCA) is one of the most severe forms of inherited retinal degeneration and can be caused by mutations in at least 15 different genes. To clarify the proteomic differences in LCA eyes, a cohort of retinal degeneration 12 (rd12) mice, an LCA2 model caused by a mutation in the RPE65 gene, were injected subretinally with an AAV vector (scAAV5-smCBA-hRPE65) in one eye, wh...
