Estrogen receptor α variants affect age at onset of Alzheimer's disease in a multiethnic female cohort.

ABSTRACT:

Background/aims

Few studies of gene variants that affect estrogen activity investigate their association with age at onset of Alzheimer's disease (AD) in women of different ethnicities. We examined the influence of ESR1 polymorphisms on age at onset of AD in a multiethnic cohort of women.

Methods

Among 1,436 women participating in the Washington Heights Inwood Columbia Aging Project, association with age at AD onset was assessed for 41 single-nucleotide polymorphisms (SNPs) on the ESR1 gene using Cox proportional hazard models, adjusting for presence of an APOE ε4 allele, years of education, and body mass index.

Results

Six SNPs in self-identified White women were protectively associated with delayed age of AD onset in this self-identified group, including the two res
