GeneCards Summary for MT-ND2 Gene

MT-ND2 (Mitochondrially Encoded NADH:Ubiquinone Oxidoreductase Core Subunit 2) is a Protein Coding gene. Diseases associated with MT-ND2 include Leber Hereditary Optic Neuropathy and Alzheimer Disease Mitochondrial. Among its related pathways are Metabolism and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins.. Gene Ontology (GO) annotations related to this gene include NADH dehydrogenase (ubiquinone) activity.

UniProtKB/Swiss-Prot for MT-ND2 Gene

  • Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone (By similarity).

  • Leber hereditary optic neuropathy (LHON) [MIM:535000]: A maternally inherited disease resulting in acute or subacute loss of central vision, due to optic nerve dysfunction. Cardiac conduction defects and neurological defects have also been described in some patients. LHON results from primary mitochondrial DNA mutations affecting the respiratory chain complexes. {ECO:0000269 PubMed:1732158, ECO:0000269 PubMed:1900003}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Alzheimer disease mitochondrial (AD-MT) [MIM:502500]: Alzheimer disease is a neurodegenerative disorder characterized by progressive dementia, loss of cognitive abilities, and deposition of fibrillar amyloid proteins as intraneuronal neurofibrillary tangles, extracellular amyloid plaques and vascular amyloid deposits. The major constituents of these plaques are neurotoxic amyloid-beta protein 40 and amyloid-beta protein 42, that are produced by the proteolysis of the transmembrane APP protein. The cytotoxic C-terminal fragments (CTFs) and the caspase-cleaved products, such as C31, are also implicated in neuronal death. {ECO:0000269 PubMed:1370613}. Note=Disease susceptibility may be associated with variations affecting the gene represented in this entry.
