Genes affected
NDUFA8 (HGNC:7692): (NADH:ubiquinone oxidoreductase subunit A8) The protein encoded by this gene belongs to the complex I 19 kDa subunit family. Mammalian complex I is composed of 45 different subunits. This protein has NADH dehydrogenase activity and oxidoreductase activity. It plays an important role in transfering electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]
NDUFA8 Gene-Disease associations (from GenCC):
  • mitochondrial disease
    Inheritance: AR Classification: MODERATE Submitted by: ClinGen
  • mitochondrial complex I deficiency, nuclear type 37
