应用分子生物学新技术,使用DNA探针和限制性片段长度多态性,可以直接或间接地分析病变基因缺陷,进行产前诊断,症状前诊断和携带者检测。并且,还可以直接分析一些蛋白和酶水平缺陷尚不清楚的疾病。近年,神经遗传病的研究和发展极为迅速,极大地促进了人们对许多神经系统少见遗传病的了 The application of new molecular biology techniques, using DNA probes and restriction fragment length polymorphisms, can be directly or indirectly analysis of genetic defects in lesions, prenatal diagnosis, pre-symptoms diagnosis and carrier detection. And, you can also directly analyze some of the protein and enzyme level defects are not yet clear disease. In recent years, the research and development of neurogenetic diseases has been extremely rapid, which has greatly promoted people’s rare genetic diseases in many nervous systems
