APOE promoter polymorphisms and dementia in the elderly.

Abstract excerpt

Previous observations suggest a contribution of two APOE promoter polymorphisms (-219 G/T and -491 A/T) in dementia. From two independent populations of elderly (mean age of 84 and 85 years old, respectively), we observed that subjects bearing the -219T allele were at increased risk of dementia (OR = 1.9 (95% CI, 1.3-2.8), P = 0.0003) or AD (OR = 2.0 (95% CI, 1.2-3.4), P < 0.008). Conversely, the -491 A/T variant...
