Filter by:Inborn Errors of metabolism comprise a large number of rare conditions with a collective incidence of around 1/2000 newborns. Many disorders are treatable provided that a correct diagnosis can be established in time, and for many diseases novel therapies are being developed. Without treatment, many of the conditions result in early death or severe irreversible handicaps. The Centre for Inherited Metabolic Diseases, CMMS at Karolinska university hospital, is an integrated expert center where clinical specialists work closely together with experts in laboratory medicine, combining clinical genetics, clinical chemistry, pediatrics, neurology, and endocrinology. The center serves the whole Swedish population with diagnostics and expert advice on IEM and has a broad arsenal of biochemical investigations designed to detect defects in intermediary metabolism.
The primary objective of this study is to assess the safety of vatiquinone in participants with inherited mitochondrial disease who had prior exposure to vatiquinone in a PTC/BioElectron sponsored (previously Edison) clinical study or treatment plan. The study will continue until vatiquinone becomes commercially available or the program is terminated.
The purpose of this study is to perform a "muscle phenotyping" magnetic resonance imaging (MRI) assessment in patients receiving clinical care at the Children's Hospital of Philadelphia (CHOP) for mitochondrial disease that is either suspected (based on clinical presentation) or has a definite genetic diagnosis. The MRI assessment quantifies skeletal muscle oxidative phosphorylation (OXPHOS) capacity. Investigators hope that this study will contribute to our current knowledge of mitochondrial diseases and this study will help create a new diagnostic tool for use in both clinical care and in clinical trials.
The investigators will evaluate whether sulfamethoxazole, a sulfamide antibiotic, improves the symptoms of primary PREPL deficiency (hypotonia-cystinuria syndrome and isolated PREPL deficiency).
The investigators are studying patients with undefined mitochondrial diseases to identify genetic mutations in nuclear or mitochondrial Deoxyribonucleic Acid (DNA). Most patients with suspected or known mitochondrial diseases have no genetic confirmation. The investigators expect that evaluating tissue samples from patients with mitochondrial disorders will lead us to discover mutations in new or known genes causing mitochondrial dysfunction.
