Genes affected
TACO1 (HGNC:24316): (translational activator of cytochrome c oxidase I) This gene encodes a mitochondrial protein that function as a translational activator of mitochondrially-encoded cytochrome c oxidase 1. Mutations in this gene are associated with Leigh syndrome.[provided by RefSeq, Mar 2010]
