5 Molecular biological studies of SOD1 gene mutation in Chinese patients with Familiar Amyotrophic Lateral Sclerosis
Abstract Objective: identificate mutation of SOD1 gene in Chinese familiar amyotrophic lateral sclerosis patients and analyze of genotype-phenotype relationship. we essfully constructed the eukaryotic expression plasmid of normal and mutated SOD1 gene for the further study of amyotrophic lateral sclerosis pathogenesis. Methods: polymerase chain reaction and DNA sequencing techniques, probands of 8 amyotrophic lateral sclerosis families were screened for SOD1 mutation. analyses of the FALS families. , Gly147Asp and wild type SOD1cDNA/,SOD1cDNA/ PEGP/N2 eukaryotic expression plasmid were constructed by restriction endonuclease, T4 DNA ligase and site-directed mutag
