In addition, rs4147929 of ABCA7 was correlated with the risk of developing AD in the allele (P = 0.006, OR = 1.45, 95% CI 1.11–1.89) without adjusting the age and gender, dominant (P = 0.012, OR = 1.59, 95% CI 1.11–2.27) and additive (P = 0.010, OR = 1.40, 95% CI 1.08–1.81) models after adjusting the age and gender. Here, ABCA7 is linked to Alzheimer disease.
