This study was designed to investigate the effect of platelet glycoprotein Ib alpha Kozak polymorphism on the clinical presentation of the patients with acute pulmonary embolism. Methods Forty-two patients with pulmonary embolism were genotyped for Kozak polymorphism of the glycoprotein Ib alpha by polymerase chain reaction/restriction fragment length polymorphism. Results Carriers of the -5T/C polymorphism of glycoprotein Ib alpha were significantly over-represented in the patient group with clinically massive or submassive pulmonary embolism (odds ratio 5.5, 95% confidence interval 1.4 to 22.2, P = 0.023). Also the association between this polymorphism and massive or submassive pulmonary embolism still existed even after being adjusted for conventional risk factors. Conclusion The -5T/C polymorphism in the Kozak sequence of glycoprotein Ib alpha may present as a risk factor for clinical manifestation of pulmonary embolism in which clot burden plays an important role.en10.1007/s11239-008-0204-3info:eu-repo/semantics/closedAccessPulmonary embolismKozak polymorphismGlycoprotein receptor complexArticle27325926618283530Q2WOS:000264886300002Q3
