VEGFA and Schnyder corneal dystrophy: Our results indicated that in the codominant model, the VEGF-2578-CA genotype was strongly associated with increased SCD severity with OR 2.56 (95%) CI = (1.36 to 4.82) RR = 1.69 (1.16 to 2.45) p < 0.003 whereas VEGF-2578-AA genotype was not associated with SCD severity with OR 0.65 (95%) CI = (0.29 to 1.42), RR = 0.84 (0.63 to 1.130) p < 0.28.
