摘要: 为了探讨神经肌肉性疾病的发病与线粒体DNA突变的关系,采用PCR技术检测了 20例患有不同神经肌肉性疾病儿童的外周血和骨骼肌细胞中的线粒体DNA(mtDNA),发现其中6例患儿有mtDNA缺失,其中1例至少有2968bp片段的缺失, 另5例至少有2000bp片段的缺失,此缺失区位于线粒体呼吸链复合物1、 4、5、编码区,表明该突变对神经肌肉性疾病的发生有一定作用。
Abstract:To understand the relation to mechanism of neuromuscular disease and mtDNA mutation,using PCR technique,we investigated blood and /or skeletal muscle of 20 patients with neuromuscular diseases.A deletion in the length of 2000~2968bp was found in blood mitochondrial DNA of 6 patients with neuromuscular disease.The deletion region partially lies in the coding region of resoiratony chain complex 1,4,5.It is suggested that this mutation ois related with neuromuscular diseases.
