Genes affected
MT-TG (HGNC:7486): (mitochondrially encoded tRNA glycine)
MT-ND3 (HGNC:7458): (mitochondrially encoded NADH dehydrogenase 3) Enables NADH dehydrogenase (ubiquinone) activity. Involved in mitochondrial electron transport, NADH to ubiquinone. Part of mitochondrial respiratory chain complex I. Implicated in Leber hereditary optic neuropathy; Leigh disease; and Parkinson's disease. [provided by Alliance of Genome Resources, Apr 2022]
MT-CO3 (HGNC:7422): (mitochondrially encoded cytochrome c oxidase III) Predicted to enable electron transfer activity and oxidoreduction-driven active transmembrane transporter activity. Involved in respiratory chain complex IV assembly. Part of respiratory chain complex IV. Implicated in MELAS syndrome. [provided by Alliance of Genome Resources, Apr 2022]
