Mitochondrial COX2 gene

The mitochondrial gene MT-CO2 encodes an enzyme responsible for electron transport on the inner mitochondrial membrane. It is subunit 2 of the cytochome c oxidase, belonging to respiratory complex IV. The gene is encoded by nucleotides 7586-8294. Diseases caused by mutations include cytochrome c oxydase deficiency and colorectal cancer. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
