Has abstract Autosomal-recessive optic neuropathies are
Autosomal-recessive optic neuropathies are rare blinding conditions related to retinal ganglion cell (RGC) and optic-nerve degeneration, for which only mutations in ''TMEM126A'' and ''ACO2'' are known. In four families with early-onset recessive optic neuropathy, we identified mutations in ''RTN4IP1'', which encodes a mitochondrial ubiquinol oxydo-reductase. ''RTN4IP1'' is a partner of ''RTN4'' (also known as NOGO), and its ortholog Rad8 in ''C. elegans'' is involved in UV light response. Analysis of fibroblasts from affected individuals with a ''RTN4IP1'' mutation showed loss of the altered protein, a deficit of mitochondrial respiratory complex I and IV activities, and increased susceptibility to UV light. Silencing of RTN4IP1 altered the number and morphogenesis of mouse RGC dendrites ''in vitro'' and the eye size, neuro-retinal development, and swimming behavior in zebrafish ''in vivo''. Altogether, these data point to a pathophysiological mechanism responsible for RGC early degeneration and optic neuropathy and linking ''RTN4IP1'' functions to mitochondrial physiology, response to UV light, and dendrite growth during eye maturation.
