MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an nuclear-encoded accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (complex I, or NADH:ubiquinone oxidoreductase). Complex I removes electrons from NADH and passes them to the electron acceptor ubiquinone. Mutations in this gene can cause mitochondrial complex I deficiencies such as Leigh syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]
PHENOTYPE: Mice homozygous for a null allele exhibit growth retardation, lethargy, loss of motor skills, blindness and decreased mitochondrial CI complex activity beginning at 5 weeks of age followed by death at week 7. [provided by MGI curators]
