| 摘 要： | 目的在一个聚合酶链式反应(polymerasechain reaction,PCR)管中运用错配PCR技术直接检测母系遗传性非综合征型聋相关的线粒体DNA C1494T突变。方法设计一对引物对母系遗传性非综合征型聋相关的线粒体DNA C1494T突变的单碱基错配引物,即在引物的3’端附近引入一个与模板错配的碱基。用此引物进行多聚酶链式反应,再通过琼脂糖凝胶电泳观察结果。结果通过电泳结果可以直观判断患者是否携带线粒体DNA C1494T突变,结果与测序结果一致。结论错配PCR技术可以准确、方便、快速检测线粒体DNA C1494T突变,适于在基层开展和应用。

| Abstract: | OBJECTIVE To detect C1494T mutation associated with maternally transmitted aminoglycosideinduced and nonsyndromic deafness in one pipe with mispairing PCR.METHODS A pair of mispairing primer according to mitochondrial DNA C1494T mutation was designed.PCR was carried out with designed primer,and the results were observed through agarose gel electrophoresis.RESULTS We could judge mitochondrial DNA C1494T mutation easily,and the results were identical with sequencing.CONCLUSION Mispairing PCR method can accurately,convenient,quickly detect mitochondrial DNA C1494T mutation and is suitable for application in the basic unit. |
