ABSTRACT: Increasing evidences suggest that polymorphisms within the promoter region of the vascular endothelial growth factor (VEGF) gene may elevate the risk for Alzheimer's disease (AD). In Northern Chinese Han, we found three polymorphisms in the VEGF promoter: -2578C/A (rs699947), -2549I/D (rs35569394) and -1154G/A (rs1570360). A strong linkage disequilibrium was detected between -2578C/A and -2549I/D. After adjusting the data by gender, age and the APOEepsilon4 status using logistic regression, the -1154G/G genotype was found to increase the risk for sporadic AD (SAD) by 1.4-folds. In the subgroup of APOEepsilon4 non-carriers, the -1154G allele and -2549D/-1154G haplotype were observed to be significantly higher in the 279 SAD patients than in the 317 healthy individuals. The present study provides the evidence that the -1154G allele and the -2549D/-1154G haplotype may be associated with the development of SAD in the individuals without APOEepsilon4 allele.
