Optic neuropathy

Gene: NDUFV1

Green List (high evidence)

Recently accepted publication "Recessive variants in mitochondrial Complex I nuclear subunits are an underrated cause of optic atrophy" reports Complex I genes, which pathogenic defects lead to optic atrophy; LHON-like phenotypes.
1 family was carrying NDUFV1 pathogenic variant and affected individual was diagnoses with optic neuropathy

Defects in core CI subunits in reported cohort lead to isolated optic atrophy, while defects in accessory CI subunits and assembly factors resulted in a spectrum of phenotypes, from isolated to syndromic optic atrophy. For 12 cases, the subacute onset of vision loss enabled us to associate or confirm novel genes (NDUFS7, NDUFV1, NDUFAF2, NDUFAF4, NDUFAF8) with the autosomal recessive Leber Hereditary Optic Neuropathy (arLHON) phenotype. Moreover, in the NDUFS7 subunit a partial spatial segregation was noted for missense variants causing either Leigh syndrome or isolated optic atrophy, hinting at possible disease-specific molecular defect.
