The Role of Genetic Variants (rs869109213 and rs2070744) Of the <i>eNOS</i> Gene and <i>Bgl</i>II in the α<sub>2</sub> Subunit of the α<sub>2</sub>β<sub>1</sub> Integrin Gene in Diabetic Retinopathy in a Tunisian Population.
We found a significant association between the genotypes of NOS3 rs869109213 polymorphism and the risk of DR in the co-dominant model (4a4b genotype; 1.99-fold increased risk [1.09-3.65]; 95% confidence interval [CI]; p = 0.02), co-dominant model (4a4a genotype; 4.16-fold increased risk [1.03-16.74]; 95% CI; p = 0.04), and dominant model (4a4a and 4a4b genotypes; 2.22-fold increased risk [1.26-3.92]; 95% CI; p = 0.01) compared to the 4b4b genotype.
