Leber hereditary optic neuropathy mtDNA mutations in Europe.
Dr Patrick Yu-Wai-Man, an ophthalmologist at Newcastle University, has used a neuroprotective drug called idebenone, which is given orally, to treat a common inherited form of blindness called
Leber hereditary optic neuropathy (LHON).
CONTEXT:
Leber hereditary optic neuropathy (LHON) is a maternally inherited loss of central vision related to pathogenic mutations in the mitochondrial genome, which are a necessary but not sufficient condition to develop the disease.
Leber hereditary optic neuropathy is an mtDNA mutation-related mitochondrial cytopathy that suggests insights into how mitochondrial dysfunction might play a central role in classic neurodegenerative diseases and perhaps provides a precedence as well.
Since the discovery that
Leber hereditary optic neuropathy (LHON) results from mutations in mitochondrial DNA (mtDNA), considerable attention has been focused on this alternative genome and on development of the scientific tools needed to study this remarkable genetic pathway (1, 2).
M2 PHARMA-April 18, 2019-GenSight Biologics Reports Positive Follow-up Results at Week 72 of the RESCUE Phase III Clinical Trial of GS010 in
Leber Hereditary Optic NeuropathyIt is well established that autosomal dominant hereditary optic neuropathy (ADOA) is the most common type of HON, followed by
Leber hereditary optic neuropathy (LHON) and other plus syndromes associated with damage of the nervous system [1,2].
For example, an adenine-to-guanine transversion at position 4136 (A4136G) of the human mitochondrial genome, which leads to the substitution of cysteine for tyrosine in the ND1 subunit of respiratory chain complex I, has been associated with
Leber hereditary optic neuropathy (4-6).
