Association between a PS-1 intronic polymorphism and late onset Alzheimer's disease.

Abstract excerpt

Previous work suggests an association between allele 1 and the 1-1 genotype of an intronic polymorphism in the presenilin-1 (PS-1) gene and late onset Alzheimer's disease. We found an excess of the 1-1 genotype in our late onset clinical sample (p = 0.006, one-tailed) but not in our postmortem confirmed sample, which instead exhibited an excess of allele 1 (p = 0.02, one-tailed). No interaction between PS-1 and...
