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)
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)
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)
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)
BACKGROUND Creatine transporter deficiency is a monogenic cause of X-linked intellectual disability. Since its first description in 2001 several case reports have been published but an overview of phenotype, genotype and phenotype--genotype correlation has been lacking. METHODS We performed a retrospective study of clinical, biochemical and molecular(More)
The BCAP31 gene is located between SLC6A8, associated with X-linked creatine transporter deficiency, and ABCD1, associated with X-linked adrenoleukodystrophy. Recently, loss-of-function mutations in BCAP31 were reported in association with severe developmental delay, deafness and dystonia. We characterized the break points in eight patients with deletions(More)
TUBB2A is a gene that has recently been reported in association with structural brain abnormalities. Only 3 cases have been reported to date with disparate brain morphologic abnormalities, although all patients have presented with developmental delay and infantile-onset epilepsy. We report a fourth patient with a de novo variant in TUBB2A that is predicted(More)
