Abstract
The effect of the apolipoprotein E (APOE) Ο΅4 allele on age of onset was analyzed in two groups of families with earlyβonset Alzheimer's disease (AD), (1) Volga German (VG) kindreds, in which AD is caused by an unknown locus and (2) earlyβonset nonβVG families showing evidence of linkage to chromosome 14. The Ο΅4 allele did not have a detectable effect on age of onset in either group. This finding suggests some forms of earlyβonset familial AD are not modifiable by APOE status, or that AD can be caused by APOEβindependent pathways.

The apolipoprotein E (ApoE) genotype is a significant risk factor and modulator of age of onset of Alzheimer's disease (AD). We analyzed the effect of the ApoE genotype in two distinct early-onset familial AD groups: families with a mutation in the presenilin-1 gene (PS-1) on chromosome 14, and fami
