Genes affected

TRNY (HGNC:7502): (mitochondrially encoded tRNA tyrosine)

COX1 (HGNC:7419): (mitochondrially encoded cytochrome c oxidase I) Contributes to cytochrome-c oxidase activity. Predicted to be involved in electron transport coupled proton transport and mitochondrial electron transport, cytochrome c to oxygen. Part of mitochondrial respiratory chain complex III and mitochondrial respiratory chain complex IV. [provided by Alliance of Genome Resources, Apr 2022]

TRNN (HGNC:7493): (mitochondrially encoded tRNA asparagine)

TRNA (HGNC:7475): (mitochondrially encoded tRNA alanine)

TRNC (HGNC:7477): (mitochondrially encoded tRNA cysteine)
