Apolipoprotein E region molecular signatures of Alzheimer's disease.

ABSTRACT: Although the APOE region is the strongest genetic risk factor for Alzheimer's diseases (ADs), its pathogenic role remains poorly understood. Elucidating genetic predisposition to ADs, a subset of age-related diseases characteristic for postreproductive period, is hampered by the undefined role of evolution in establishing molecular mechanisms of such diseases. This uncertainty is inevitable source of natural-selection-free genetic heterogeneity in predisposition to ADs. We performed first large-scale analysis of linkage disequilibrium (LD) structures characterized by 30 polymorphisms from five genes in the APOE 19q13.3 region (BCAM, NECTIN2, TOMM40, APOE, and APOC1) in 2,673 AD-affected and 16,246 unaffected individuals from five cohorts. Consistent with the undefined role of evolution in
