Mitochondrial complex I deficiency
MONDO:0100133A type of mitochondrial disease charcterized by macrocephaly (large head) with progressive leukodystrophy, encephalopathy, hypertrophic cardiomyopathy, myopathy, liver disease, Leigh syndrome, Leber hereditary optic neuropathy, and some forms of Parkinson disease. The disease is caused by mutations in any of many genes and the inheritance pattern depends on the responsible gene.
Also known as: NADH coenzyme Q reductase deficiency, complex 1 mitochondrial respiratory chain deficiency, isolated NADH-CoQ reductase deficiency, isolated NADH-coenzyme Q reductase deficiency, isolated NADH-ubiquinone reductase deficiency, isolated complex I deficiency, isolated mitochondrial respiratory chain complex I deficiency, mitochondrial respiratory chain complex I deficiency

Last chance access: vatiquinone for mitochondrial disease patients
Disease control Expanded access (ended)This program offered vatiquinone, an experimental liquid medication, to patients with inherited mitochondrial diseases like Leigh syndrome who had already completed a previous safety study. The goal was to continue treatment for those who might benefit, but enrollment is now clos…

Massive gene hunt launched for mysterious mitochondrial diseases
Knowledge-focused By invitation onlyThis study aims to discover new genetic mutations that cause mitochondrial disorders by analyzing tissue samples from up to 6,900 participants. It includes people with suspected or known mitochondrial diseases, such as MELAS or Leigh's Disease, who lack a genetic diagnosis. The r…
