Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) is a multisystemic mitochondrial disorder (Pavlakis et al. Advances in Contemporary Neurology. Philadelphia: Davis, 1988: 95-133) and most patients with the typical MELAS phenotype have a point mutation in mitochondrial DNA, an A to G transition at nucleotide 3243 (Goto et al. Nature 1990; 348; 651-653; Koboyashi et al. Biochem Biophys Res Commun 1990; 173: 816-822; Ciafaloni et al. Ann Neurol 1992; 31: 391-398). A 9-yr-old boy presenting with chronic asthma and depression was found to have abnormal mitochondria, partial defects of respiratory chain enzymes, and the MELAS point mutation.
线粒体脑肌病伴乳酸酸中毒及卒中样发作(MELAS)是一种多系统线粒体疾病(帕夫拉基斯等人,《当代神经病学进展》。费城:戴维斯,1988年:95 - 133),大多数具有典型MELAS表型的患者线粒体DNA存在点突变,即核苷酸3243处的A到G转换(后藤等人,《自然》1990年;348;651 - 653;小林等人,《生物化学与生物物理研究通讯》1990年;173:816 - 822;恰法洛尼等人,《神经病学纪事》1992年;31:391 - 398)。一名9岁男孩,患有慢性哮喘和抑郁症,被发现存在线粒体异常、呼吸链酶部分缺陷以及MELAS点突变。
