Abstract
Pigment epithelium-derived factor (PEDF) has recently been shown to be the most potent inhibitor of angiogenesis in the mammalian eye. We, along with others, have very recently found that loss of PEDF is involved in the development and progression of diabetic retinopathy. However, there are no studies on the allelic effects of PEDF gene polymorphism in diabetic retinopathy. In this study, we investigated whether a functional amino acid change, a methionine to threonine polymorphism (Met72Thr polymorphism) of the PEDF gene, is associated with microangiopathy in 143 patients with diabetes. We found that there were no significant associations between PEDF Met72Thr gene polymorphism and diabetic microangiopathy. These observations suggest that these genetic variants might not be involved in the mechanism of diabetic microangiopathy in patients with diabetes.
