Genes affected

MT-ND5 (HGNC:7461): (mitochondrially encoded NADH dehydrogenase 5) Enables NADH dehydrogenase (ubiquinone) activity. Involved in mitochondrial electron transport, NADH to ubiquinone and mitochondrial respiratory chain complex I assembly. Part of mitochondrial respiratory chain complex I. Implicated in Leber hereditary optic neuropathy; Leigh disease; and MELAS syndrome. [provided by Alliance of Genome Resources, Apr 2022]

MT-TL2 (HGNC:7491): (mitochondrially encoded tRNA leucine 2 (CUN))

TRNL2 (HGNC:):
