The prothrombin gene G20210A mutation and the platelet glycoprotein IIIa polymorphism PlA2 in patients with central retinal vein occlusion.
The prothrombin gene G20210A mutation and the platelet glycoprotein IIIa polymorphism PlA2 have been shown to be associated with thromboembolic disease. We wondered if mutations were overrepresented in patients with central retinal vein occlusion. We studied 129 consecutive patients with a history of central retinal vein occlusion. We analysed for the prothrombin gene G20210A mutation and the platelet glycoprotein IIIa polymorphism PlA2 and compared the results to controls with no history of thrombosis. For the platelet glycoprotein IIIa polymorphism PlA2, 69% were normal, 26% were heterozygous, and 5% were homozygous. For the G20210A prothrombin mutation, 97% were normal and 3% were heterozygous. Neither the prothrombin gene G20210A mutation nor the platelet glycoprotein IIIa polymorphism PlA2 seem to be associated with central retinal vein occlusion.
