title: Evaluation of the prothrombin gene polymorphism in patients with advanced retinopathy of prematurity.
abstract: It has been reported recently that a common genetic variant in the 3'-untranslated region of the prothrombin gene is associated with a significant fraction of premature births. The purpose of this study is to evaluate the prothrombin gene polymorphism in a large cohort of patients with preterm birth and advanced retinopathy of prematurity. For this purpose, the leukocyte DNAs were analyzed for the mutation (20210A) in the 3'-untranslated region of the prothrombin gene by PCR amplification, followed by restriction analysis and DNA sequencing. Our extensive analysis revealed a normal genotype (GG) in all patients as well as controls. These results suggest that the common genetic variant in the 3'-untranslated region of the prothrombin gene is not associated with advanced retinopathy of prematurity. Although more patients' samples should be evaluated, this genetic test does not support a relationship between prothrombin gene mutation and retinopathy of prematurity.
