Inborn mitochondrial metabolism disorder
MONDO:0004069Diseases caused by abnormal function of the mitochondria. They may be caused by mutations, acquired or inherited, in mitochondrial dna or in nuclear genes that code for mitochondrial components. They may also be the result of acquired mitochondria dysfunction due to adverse effects of drugs, infections, or other environmental causes.
Also known as: mitochondrial disease, mitochondrial genetic disorders, mitochondrial metabolism disease
