Leber hereditary optic neuropathy.
BACKGROUND Leber hereditary optic neuropathy (LHON) is a cause of inherited blindness that typically presents with bilateral, painless, subacute visual failure in young adult males. Males are about four times more likely to be affected than females and 95% of LHON carriers become affected before the age of 50. Affected patients may have characteristic ocular fundal appearances and have evidence...

R elatively little progress has been made in developing therapies for mitochondrial diseases in modern medicine as a result of the exquisite complexity of the structural proteins and pathways associated with mitochondrial functions and our incomplete understanding of pathophysiology (1). Leber hereditary optic neuropathy (LHON), in particular, provides a unique model for understanding molecular...
متن کاملVariation in OPA1 does not explain the incomplete penetrance of Leber hereditary optic neuropathy
PURPOSE Leber hereditary optic neuropathy (LHON) is a common cause of inherited blindness, primarily due to one of three mitochondrial DNA (mtDNA) mutations. These mtDNA pathogenic mutations have variable clinical penetrance. Recent linkage evidence raised the possibility that the nuclear gene optic atrophy 1 (OPA1) determines whether mtDNA mutation carriers develop blindness. To validate these...
