| Research Abstract |
From mitochondrial DNA analyses and pathologic evaluation, 117 patients have been diagnosed as having mitochondrial disorders, including 28 patients with progressive external ophthalmoplegia (CPEO), 42 with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS), and 4 with myoclonus epilepsy with ragged-red fibers (MERRF). All mitochondrial DNA extract ed from muscles and/or blood samples have been kept in our DNA bank system, and are now provided to many researchers all over the world. For 350 patients with progressive muscular dystrophies, defects in the dystrophin gene were analysed and dystrophin tests including immunostaining and immunoblotting were applied to confirm dystrophin abnormalities. In addition, 40 patients were diagnosed as having metabolic myopathies including 17 patients with glycogen storage diseases and 4 with carnitine palmitoyltransferase deficiency. All muscle samples have been kept in our bank system for future study.
