It has been ascribed to variants in the mitochondrial genome, mainly the m.3460G&amp;gt;A, m.11778G&amp;gt;A and m.14484T&amp;gt;C mutations in ND1, ND4 and ND6, respectively. Nonetheless, inconclusive molecular diagnosis is not uncommon. Recently, biallelic mutations in the NDUFS2, DNAJC30, MCAT and NDUFA12 nuclear genes have been identified in unresolved LHON cases, identifying an autosomal recessive LHON (arLHON, OMIM:619382). The clinical presentation of arLHON copies that of typical LHON due to mtDNA mutations (mtLHON), with an acute phase of sudden and severe vision loss, telangiectatic and tortuous vessels around the optic nerve and swelling of the retinal nerve fibre layer. This is followed by a chronic phase of retinal nerve fibre layer loss, but eventually affected individuals recover partial or full visual acuity. Idebenone treatment significantly improved vision recovery in DNAJC30-associated patients. As for mtLHON, arLHON predominantly affected male compared with female carriers. The discovery of arLHON cases breaks with the dogma of exclusive maternal inheritance. It defines a new neuro-ophthalmo-genetic paradigm, which should be considered in individuals manifesting a LHON phenotype but with an inconclusive molecular diagnosis. NDUFS2, DNAJC30, MCAT and NDUFA12 should be investigated in these individuals, knowing that other arLHON genes might exist.<\/jats:p>","DOI":"10.1093\/brain\/awad131","type":"journal-article","created":{"date-parts":[[2023,4,18]],"date-time":"2023-04-18T13:16:09Z","timestamp":1681823769000},"page":"3156-3161","source":"Crossref","is-referenced-by-count":35,"title":["Autosomal
