Pterygium and genetic polymorphism of DNA double strand break repair gene Ku70.

Abstract

The Ku70 promoter T-991C, but not the Ku70 promoter C-57G polymorphism, is correlated with pterygium. The Ku70 promoter T-991C polymorphism might become a potential marker for the prediction of pterygium susceptibility. It also provides a valuable insight into the pathogenesis of pterygium.
