Gene augmentation for X-linked retinitis pigmentosa caused by mutations in RPGR.
X-linked retinitis pigmentosa (XLRP) caused by mutations in the RPGR gene is a severe and early onset form of retinal degeneration, and no treatment is currently available. Recent evidence in two clinically relevant canine models shows that adeno-associated viral (AAV)-mediated RPGR gene transfer to rods and cones can prevent disease onset and rescue photoreceptors at early- and mid-stages of d...
متن کاملDisease course of patients with X-linked retinitis pigmentosa due to RPGR gene mutations.
PURPOSE To measure the rates of visual acuity, visual field, and ERG loss in patients with X-linked retinitis pigmentosa due to RPGR mutations and to determine whether these rates differ from those of patients with dominant retinitis pigmentosa due to RHO mutations. METHODS Snellen visual acuities, Goldmann visual field areas (V4e white test light), and 30 Hz (cone) full-field ERG amplitudes ...
متن کاملA retinitis pigmentosa GTPase regulator (RPGR)-deficient mouse model for X-linked retinitis pigmentosa (RP3).
The X-linked RP3 locus codes for retinitis pigmentosa GTPase regulator (RPGR), a protein of unknown function with sequence homology to the guanine nucleotide exchange factor for Ran GTPase. We created an RPGR-deficient murine model by gene knockout. In the mutant mice, cone photoreceptors exhibit ectopic localization of cone opsins in the cell body and synapses and rod photoreceptors have a red...
متن کاملDominant X linked retinitis pigmentosa is frequently accounted for by truncating mutations in exon ORF15 of the RPGR gene.
Retinitis pigmentosa (RP) is a group of progressive hereditary disorders of the retina in which various modes of inheritance have been described. The X linked forms of retinitis pigmentosa (XLRP, MIM 268000) are among the most severe owing to their early onset, leading to significant vision loss before the fourth decade. Five XLRP loci have been localised by linkage: RP2 (MIM 312600), RP3 (MIM ...
متن کاملInner retinal abnormalities in X-linked retinitis pigmentosa with RPGR mutations.
PURPOSE To investigate in vivo the retinal microstructure in X-linked retinitis pigmentosa (XLRP) caused by RPGR mutations as a prelude to treatment initiatives for this common form of RP. METHODS Patients with RPGR-XLRP (n = 12; age range, 10-56 years) were studied by optical coherence tomography (OCT) in a wide region of central retina. Overall retinal thickness and outer nuclear layer (ONL...
