PURPOSE The purpose of this statement is to review the literature regarding mitochondrial disease and to provide recommendations for optimal diagnosis and treatment. This statement is intended for physicians who are engaged in diagnosing and treating these patients. METHODS The Writing Group members were appointed by the Mitochondrial Medicine Society.(More)
This report presents the case of an adult male with aromatic L-amino acid decarboxylase deficiency who developed serious cardiac rhythm disturbances during treatment with intravenous dopamine and norepinephrine for severe hypotension. Three weeks later, he spontaneously developed atrial fibrillation while not receiving exogenous catecholamines. He died(More)
An 8-½ year old boy with glutaric aciduria type I (GA1) and chronic dystonia presented with severe rhabdomyolysis in association with a febrile illness. His clinical course was complicated by acute renal failure, cardiac arrest and hypoxic ischemic encephalopathy. As acute neurological decompensation is typically not seen in patients with GA1 beyond early(More)
The treatment of mitochondrial disease varies considerably. Most experts use a combination of vitamins, optimize patients' nutrition and general health, and prevent worsening of symptoms during times of illness and physiologic stress. We agree with this approach, and we agree that therapies using vitamins and cofactors have value, though there is debate(More)
Combined oxidative phosphorylation deficiency type 7 (COXPD7) is a rare disorder of mitochondrial metabolism that results in optic atrophy and Leigh syndrome-like disease. We describe 2 siblings with compound heterozygous mutations in the recently identified C12orf65 gene who presented with optic atrophy and mild developmental delays and subsequently(More)
Progeria, a rare genetic disorder, is characterized by severe growth failure, premature aging, and very early atherosclerosis with coronary artery and cerebrovascular disease. There has been no detailed description of progressive cerebrovascular changes in progeria or any attempted neurologic correlation of those changes. A 5-year-old boy developed signs of(More)
We describe a large Lebanese family with two affected members, a young female proband and her male cousin, who had multisystem involvement including profound global developmental delay, severe hypotonia and weakness, respiratory insufficiency, blindness, and lactic acidemia-findings consistent with an underlying mitochondrial disorder. Whole-exome(More)
Mutations in SUCLA2 result in succinyl-CoA ligase (ATP-forming) or succinyl-CoA synthetase (ADP-forming) (A-SCS) deficiency, a mitochondrial tricarboxylic acid cycle disorder. The phenotype associated with this gene defect is largely encephalomyopathy. We describe two siblings compound heterozygous for SUCLA2 mutations, c.985A>G (p.M329V) and c.920C>T(More)
