MELAS syndrome
MONDO:0010789MELAS (Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke) syndrome is a rare progressive multisystemic disorder characterized by encephalomyopathy, lactic acidosis, and stroke-like episodes. Other features include endocrinopathy, heart disease, diabetes, hearing loss, and neurological and psychiatric manifestations.
Also known as: MELAS syndrome, mitochondrial encephalomyopathy, lactic acidosis and stroke, mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes, mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes, mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes, MELAS, mitochondrial encephalomyopathy lactic acidosis and stroke-like episodes
