Novel Point Mutations and A8027G Polymorphism in Mitochondrial‐DNA‐Encoded Cytochrome c Oxidase II Gene in Mexican Patients with Probable Alzheimer Disease

International Journal of Alzheimer’s Disease, Volume 2014, Issue 1, 2014., 2014
Mitochondrial dysfunction has been thought to contribute to Alzheimer disease (AD) pathogenesis through the accumulation of mitochondrial DNA mutations and net production of reactive oxygen species (ROS). Mitochondrial cytochrome c‐oxidase plays a key role in the regulation of aerobic production of energy and is composed of 13 subunits.
