NCIt definition : Human MT-CO1 wild-type allele is located within the circular mitochondrial (MT) chromosome
and is approximately 1 kb in length. This allele, which encodes cytochrome c oxidase
subunit 1, is involved in positive regulation of the mitochondrial electron transport
chain. Allelic variation of the gene is associated with Leber hereditary optic neuropathy
(LHON). Mutation of the gene is associated with mitochondrial complex IV deficiency
(MT-C4D), recurrent mitochondrial myoglobinuria, and mitochondrially inherited nonsyndromic
sensorineural deafness. Mutations may also be associated with colorectal cancer.;
