    • The vascular hypothesis of Alzheimer's disease (AD) has brought the vascular endothelial growth factor (VEGF) into focus. The genomic region including the VEGF gene has been linked to AD and single nucleotide polymorphisms (SNPs) of the VEGF have in previous studies been associated with AD risk. To further evaluate these findings, we genotyped two SNPs in the VEGF gene (rs699947 -2578) and rs1570360 -1154) by TaqMan Allelic Discrimination in a study sample including AD patients (n = 801) and controls (n = 286). In a subgroup of the population these SNPs were analyzed in relation to APOE epsilon 4 genotype, to cerebrospinal fluid biomarkers (T-tau, P-tau, and beta(42)-Amyloid) as well as to neuropathological markers for AD (neurofibrillary tangles and senile plaques). No significant associations with risk for AD or any of the studied biomarkers could be found in this study, thus not supporting VEGF as being a major risk gene for AD.

    • Alzheimer's disease (AD) and age-related macular degeneration (AMD) share several epidemiological and biochemical features. The present study aimed to assess the possible influence of the AMD-associated complement factor H (CFH) Y402H (1277T > C) polymorphism on the risk of AD. Caucasian subjects (n=800) meeting the criteria for probable (n = 717) or definite (n = 83) AD and Caucasian non-demented controls (n 1265) were included in this multi-center case-control study, in which genotype and allele frequencies of the CFH 1277T > C polymorphism were determined and related to diagnosis, APOE genotype, Mini-Mental State Examination score (MMSE) and the cerebrospinal fluid (CSF) biomarkers total-tau (T-tau), phospho-tau(181), (P-tau(181)), and beta-amyloid(1-42) (A beta(1-42)). The AMD-associated CFH genotypes (1277CC and 1277TC) were overrepresented in subjects with AD as compared to control individuals (P = 0.029). Positive C carrier status was associated with an odds ratio (OR) for AD of 1.24 (95% confidence interval CI 1.02-1.50). When APOE 4 carrier status was included in the regression model, this association was even stronger (OR 1.34, 95% CI: 1.08-1.65, P=0.007). Subgroup analysis showed that the association between CFH C allele positivity and AD was only evident for individuals carrying the APOE epsilon 4 allele. Positive C carrier status was also associated with lower levels of CSF A beta(1-42) selectively in the control group in an APOE epsilon 4-independent manner (P=0.003). In conclusion, the CFH 1277T > C polymorphism seems to influence the risk of AD and there appears to be an interaction between CFH 1277C and APOE epsilon 4 alleles. The CFH 1277C allele may predispose patients for co-morbidity in AD and AMD. (c) 2007 Wiley-Liss, Inc.
