Dominant optic atrophy was first described clinically by Batten in 1896 and named Kjer’s optic neuropathy in 1959 after Danish ophthalmologist Poul Kjer, who studied 19 families with the disease. [3] Although dominant optic atrophy is the most common autosomally inherited optic neuropathy (i.e., disease of the optic nerves), it is often ...
Dominant optic atrophy (DOA) in particular has been traced to mutations in the GTPase domain of OPA1, leading to sensorineural hearing loss, ataxia, sensorimotor neuropathy, progressive external ophthalmoplegia, and mitochondrial myopathy.
Dominant optic atrophy is an autosomal dominant disease caused by a defect in the nuclear gene OPA1. A slowly progressive optic neuropathy, dominant optic atrophy, usually presents in the first decade of life and is bilaterally symmetrical.
Paul Kjer is a Danish ophthalmologist who studied a condition in nineteen families that was characterized by infantile optic atrophy along with a dominant inheritance mode. In 1959, the condition was named Kjer's optic neuropathy in his honor. [1]
Bosch–Boonstra–Schaaf optic atrophy syndrome is a rare autosomally inherited condition characterised by developmental delay, intellectual disability and decreased visual acuity. [ 2 ] [ 3 ] [ 4 ] Presentation
The mother was the most affected: her phenotype consisted of additional features her son did not suffer from, including severe vision impairment and bilateral optic nerve atrophy. [ 32 ] The fourth case report was written by Hogewind et al. , whose patients were three affected members of a two-generation Dutch family (two brothers and their ...
Optic atrophy in early childhood, associated with ataxia, spasticity, mental retardation, and posterior column sensory loss Behr syndrome has an autosomal recessive pattern of inheritance . Behr syndrome is characterized by the association of early-onset optic atrophy with spinocerebellar degeneration resulting in ataxia , pyramidal signs ...
Leber hereditary optic neuropathy is a condition related to changes in mitochondrial DNA. Although most DNA is packaged in chromosomes within the nucleus, mitochondria have a distinct mitochondrial genome composed of mtDNA. Mutations in the MT-ND1, MT-ND4, MT-ND4L, and MT-ND6 genes cause Leber hereditary optic neuropathy. [6]
