We found a significant association between the A allele at rs699947 with DR (odds ratio = 1.84 (95% confidence interval = 1.28-2.66); P = 0.001 vs. noDR).
In our work, we searched for an association between the -460C> (rs833061) and -634G>C (rs2010963) polymorphisms of the VEGF gene and the occurrence of AMD and its dry and wet forms.
However, weak correlations between 10 SNPs (CFH rs1329428 TT genotype, CFH rs3753394 CC genotype and T allele, CFH rs1410996 AA genotype, CFH rs800292 AA genotype, CFH rs800292 A allele, VEGF rs833061 TT genotype and C allele, VEGF rs2010963 CG genotype, VEGFR2 rs1531289 TT genotype, ARMS2 rs10490924 TT genotype, KCTD10 rs238104 GC genotype, rs1531289 T allele and ARMS2 rs10490924 T allele) and AMD were shown.
In addition, stratification by control source indicated an increased risk of CAD susceptibility with the rs699947 polymorphism for population-based studies of reduced heterogeneity.
Our overall and subgroup analyses suggested that rs699947 polymorphism was significantly associated with CHD susceptibility in both Caucasians and Asians, rs1570360 polymorphism was significantly associated with CHD susceptibility in Caucasians, and rs3025039 polymorphism was significantly associated with CHD susceptibility in Asians.
The aim of the present study is to carry out a systematic review and an updated meta-analysis in order to summarize the current published studies and to evaluate the associations between four common vascular endothelial growth factor (<i>VEGF</i>) polymorphisms (rs833061, rs1413711, rs3025039, and rs2010963) and AMD risk, also stratifying for AMD subtypes and ethnicity.
We were unable to find strong association between analyzed polymorphisms in growth factors and the severity of coronary artery disease, although there was a trend toward association between rs699947 and the severity of CAD in patients without previous MI.
Genetic polymorphisms on VEGF (rs699947) and KDR (rs2305948and rs1870377), as well as relevant haplotypes, may serve as genetic markers that might be useful in future investigations on the pathogenesis of CHD.
All of the combined effects of rs699947 (CC/CA) and rs2305948 (TT), rs3025039 (TT) and rs2305948 (TT), rs3025039 (CT) and rs1870377 (AA) had positive effects on the risk of CHD, respectively (all P < 0.05).
We were unable to find strong association between analyzed polymorphisms in growth factors and the severity of coronary artery disease, although there was a trend toward association between rs699947 and the severity of CAD in patients without previous MI.
The possible association of rs699947 and rs2010963 with CAD risks warrant confirmation in independent case-control studies and may be informative for future investigations on the pathogenesis of CAD.
Logistic regression analyses revealed that the VEGFA rs699947 C/A, VEGFA rs2010963 G/C, and VEGFA rs3025039 C/T polymorphisms were not associated with a risk of CAD.
The present meta-analyses indicated that there were no significantly associations between VEGF polymorphisms (rs833061, rs1413711, rs2010963) and the risk of AMD, although the association was different for each polymorphism among different populations.
This study tested the association between functional VEGF +405 C>G (rs2010963), -2578C>A (rs699947) polymorphisms, and coronary collaterals in patients with coronary artery disease (CAD).
In our work, we searched for an association between the -460C> (rs833061) and -634G>C (rs2010963) polymorphisms of the VEGF gene and the occurrence of AMD and its dry and wet forms.
The remaining five of the 28 polymorphisms were not associated with endometriosis: glutathione S-transferase theta 1 (GSTT1) null genotype, vascular endothelial growth factor alpha (VEGFA) rs699947, rs833061, rs2010963 and rs3025039.
In addition, genetic complement, comprising the PGF rs2268615 AA genotype and the VEGFA -460 (rs833061) T allele, was significantly associated with the development of early-onset psoriasis (P < 0.03).
All polymorphisms were in Hardy-Weinberg equilibrium, and the association by genotype with T2D-related traits displayed nominal significance for rs8192678 with glucose (<i>p</i> = 0.023) and triglycerides (<i>p</i> = 0.013); rs2010963 with diastolic blood pressure (DBP) (<i>p</i> = 0.012) and cholesterol (<i>p</i> = 0.013); rs7896005 with DBP (<i>p</i> = 0.012) and insulin (<i>p</i> = 0.011); and rs659366 with cholesterol (<i>p</i> = 0.034), glucose (<i>p</i> = 0.031) and triglycerides (<i>p</i> = 0.028); and the association of rs2010963 with HDL-C (<i>p</i> = 0.0007) was significant.
Further subgroup analyses according to ethnicity of study participants and type of disease demonstrated that the rs833061 polymorphism was significantly correlated with the risk of CHD in Asians under additive genetic model, and the rs3025039 polymorphism was significantly correlated with the risk of Tetralogy of Fallot (TOF) in dominant, recessive and allele models.
