Mitochondrial oxidative phosphorylation in autosomal dominant optic atrophy [PDF]

BMC Biochemistry, 2008
Abstract Background Autosomal dominant optic atrophy (ADOA), a form of progressive bilateral blindness due to loss of retinal ganglion cells and optic nerve deterioration, arises predominantly from mutations in the nuclear gene for the mitochondrial GTPase, OPA1.

Electrophysiological ON and OFF responses in Autosomal Dominant Optic Atrophy [PDF]

Acta Ophthalmologica, 2015
PurposeTo assess the effect of ADOA on the ON and OFF components of the photopic negative response (PhNR).MethodsTwelve participants from 6 families with OPA1 ADOA and 16 age matched controls were recruited. Electrophysiological assessment involved long flash focal (20o) and full field ERGs using red flash (664 nm, 250 msec, 55 cd/m2, 2 Hz) on a rod ...

Solving a 50 year mystery of a missing OPA1 mutation: more insights from the first family diagnosed with autosomal dominant optic atrophy [PDF]

, 2010
Background: Up to the 1950s, there was an ongoing debate about the diversity of hereditary optic neuropathies, in particular as to whether all inherited optic atrophies can be ascribed to Leber's hereditary optic neuropathy (LHON) or represent different ...

A novel AFG3L2 mutation close to AAA domain leads to aberrant OMA1 and OPA1 processing in a family with optic atrophy

Acta Neuropathologica Communications, 2020
Autosomal dominant optic atrophy (ADOA) is a neuro-ophthalmic condition characterized by bilateral degeneration of the optic nerves. Although heterozygous mutations in OPA1 represent the most common genetic cause of ADOA, a significant number of cases ...

Generation of induced pluripotent stem cells from a patient with hearing loss carrying OPA1 c.1468T>C (p.Cys490Arg) variant

Stem Cell Research, 2022
Pathogenic variants of OPA1 have been associated with autosomal dominant optic atrophy (DOA), leading to optic, auditory, and other sensorineural neuropathies and myopathies.

Inhibition of autophagy curtails visual loss in a model of autosomal dominant optic atrophy

Nature Communications, 2020
Autosomal dominant optic atrophy is caused by mutations in the mitochondrial fusion protein OPA1. Here, the authors show that AMPK-induced autophagy depletes mitochondria in axons of retinal ganglion cells and that autophagic inhibition reverses vision ...

Oxidative Stress in Optic Neuropathies

Antioxidants, 2021
Increasing evidence indicates that changes in the redox system may contribute to the pathogenesis of multiple optic neuropathies. Optic neuropathies are characterized by the neurodegeneration of the inner-most retinal neurons, the retinal ganglion cells (

Generation of an induced pluripotent stem cell line BIOi002-A from a patient with autosomal dominant optic atrophy

Stem Cell Research, 2021
Mutations of the OPA1 gene are responsible for over 70% of autosomal dominant optic atrophy patients. Peripheral blood mononuclear cells (PBMCs) were isolated from a 27–year-old patient with heterozygous c.2708_2711delTTAG mutation in the OPA1 gene ...

Spinocerebellar Ataxia Type 2 [PDF]

, 2012
1. Introduction: The autosomal dominant cerebellar ataxias (ADCA) are a clinically, pathologically and genetically heterogeneous group of neurodegenerative disorders caused by degeneration of cerebellum and its afferent and efferent connections.

Mouse Nr2f1 haploinsufficiency unveils new pathological mechanisms of a human optic atrophy syndrome

EMBO Molecular Medicine, 2019
Optic nerve atrophy represents the most common form of hereditary optic neuropathies leading to vision impairment. The recently described Bosch‐Boonstra‐Schaaf optic atrophy (BBSOA) syndrome denotes an autosomal dominant genetic form of neuropathy caused
