VEGFA and Alzheimer disease: The global study of susceptibility in AD patients showed that carriers of AA genotype and CA + AA (A-allele bearing) genotypes in the SNP VEGF rs699947 polymorphism as well as carriers of CC genotype and TC + CC (C-allele bearing) genotypes in the SNP VEGF rs833061 polymorphism had a decreased risk to develop AD, both in the codominant model, P = 0.027 OR = 0.45 (0.22–0.91), and the dominant model, P = 0.040 OR = 0.56 (0.33–0.97) after adjustment for age and gender with multivariate logistic regression analysis.
