TOMM40 ‘523 Associations with Baseline and Longitudinal Cognition in APOE ɛ3 Homozygotes

TOMM40 '523 is associated with Alzheimer's disease (AD), but APOE linkage disequilibrium confounds this association. In 170 APOE ɛ3 homozygotes, we evaluated relationships between short and very long TOMM40 alleles and longitudinal declines in three cognitive domains (attention, verbal memory, and executive function). We used factor analysis to create composite scores from 10 individual cognitive tests, and latent growth curve modeling adjusting...
