Findings

In a case-control study of almost 34,000 Caucasian individuals, the A105V variant did not associate with Alzheimer’s disease (approximately 18,000 AD and 16,000 controls; odds ratio: 2.4, p = 0.2) (Sims et al., 2017). Nor was an association between this variant and AD found in a small study of African-Americans (202 AD, 136 controls; odds ratio 0.67, p= 1) (Jin et al., 2015).
