Alzheimer's Study Find Some Variant Genes in Blacks

African-Americans have a slightly higher risk of Alzheimer’s diseasethan people of largely European ancestry, but there is no major genetic difference that could account for the slight excess risk, new research shows.

The results are from one of the only large studies ever done on Alzheimer’s in African-Americans. Researchers identified the same gene variants in older African-Americans that they had found in older people of European ancestry. But they found that African-Americans with Alzheimer’s disease were slightly more likely to have one gene, ABCA7, that is thought to confer risk for the disease.
