The frequency of ICAM-1 469KK genotype and K allele were significantly higher in the patients with diabetic retinopathy than in those without retinopathy (genotype 42% vs. 20%, chi2 = 6.70, P = 0.035; allele 66% vs. 50%, chi2 = 6.49, P = 0.011).

A number of studies evaluated the association of intracellular adhesion molecule-1 (ICAM-1) K469E (rs5498, A/G) gene polymorphism with diabetic microvascular complications (DMI) including diabetic nephropathy (DN) and diabetic retinopathy (DR) in different populations.
A significantly higher frequency of the EE genotype of the K469E polymorphism of the ICAM-1 was found in the patients with PDR compared with those without diabetic retinopathy (OR = 2.0, 95% confidence interval [CI] = 1.1-3.5; P = 0.013), whereas the G241A polymorphism of the ICAM-1 gene failed to yield an association with PDR.
Our results revealed that SNP rs5498 in ICAM-1 gene and IVS5-13insC variant in HMGA1 gene were not associated with the susceptibility of DR in the Chinese T2DM cohort.
A significantly higher frequency of the EE genotype of the K469E polymorphism of the ICAM-1 was found in the patients with PDR compared with those without diabetic retinopathy (OR = 2.0, 95% confidence interval [CI] = 1.1-3.5; P = 0.013), whereas the G241A polymorphism of the ICAM-1 gene failed to yield an association with PDR.
Binary logistic regression displays that the association of the ACE and AGT gene polymorphisms in DR patients is not significant after adjusting for confounding covariates in all the comparisons.
In a Dutch IDDM population, including 69 patients with (incipient) diabetic nephropathy, the T-allele of the AGT-M235T polymorphism is associated with an elevated UAE and diabetic retinopathy and the CC-genotype of the AT1-A1166C polymorphism is associated with hypertension.
Single nucleotide polymorphisms of vascular endothelial growth factor gene intron 2 are markers for early progression of diabetic retinopathy in Japanese with type 1 diabetes.
In conclusion, the studied VEGF SNPs were not associated with the risk of diabetic retinopathy, and so it is unlikely that the VEGF gene is a major locus determining the risk of diabetic retinopathy.
The objective of this study was to examine the genetic variations of the VEGF and eNOS gene and assess their possible relationship to DR in type 2 diabetic patients in the Indian population.
To clarify the contribution of the VEGF gene in the development of diabetic retinopathy we analyzed variants in this gene among 469 Japanese patients with type 2 diabetes.
