title: Screening of AP endonuclease as a candidate gene for amyotrophic lateral sclerosis (ALS).
abstract: DNA extracted from CNS tissue of 84 patients was screened by single-stranded conformation polymorphism (SSCP) and heteroduplex analysis for mutations in the apurinic/apyrimidinic endonuclease (APE) gene. One mutation was identified and characterized as a 4bp deletion in the 3'UTR. A rare polymorphism was identified in exon 3 and a common polymorphism in the coding region of exon 5. These results suggest that APE mutations do not account for a large number of ALS cases.
