Leber hereditary optic atrophy (LHON) [DS:H00068] is an ophthalmological disorder, characterized by acute or subacute bilateral optic atrophy that results in the loss of central vision. LHON is generally considered a mitochondrial, i.e. maternally inherited disease. Recently, autosomal recessive Leber-like hereditary optic neuropathy (LHONAR) has been described. It is caused by mutations in the nuclear encoded gene DNAJC30. The DNAJC30 protein is a chaperone protein of the mitochondrial complex I interacting with complex V to promote ATP synthesis, and is mainly expressed in neurons. It has been reported that mutations in NDUFS2 also cause LHONAR. NDUFS2 encodes a core subunit of complex I.
