There is no doubt that candidate gene association studies can play a useful part in detecting genetic variations contributing to complex diseases such as Alzheimer’s disease.1 Yasudaet al present a paper in this issue (pp772-6) in which they use this approach to test for an association between the 1-1 genotype of an intronic polymorphism in the presenilin 1 (PS-1) gene and Alzheimer’s disease, originally reported by Wragget al.2 Although Yasudaet al did not replicate this effect …
