[Platelet glycoprotein IIb/IIIa (LeuPro 33) polymorphism in stroke patients].

Area of Science:

• Genetics
• Cardiovascular Medicine
• Thrombosis

Context:

• Platelet glycoprotein IIb/IIIa (LeuPro 33) polymorphism has conflicting data regarding its role in arterial thrombosis pathogenesis.
• The prevalence of PLA1/PLA2 polymorphism varies across European populations.
• Understanding genetic predispositions is crucial for stroke risk assessment.

Purpose:

• To determine the prevalence of platelet glycoprotein IIb/IIIa (LeuPro 33) PLA1/PLA2 polymorphism in Hungarian healthy individuals and stroke patients.
• To investigate the association between this polymorphism and stroke, considering age and other risk factors.
• To explore the combined effect of PLA1/PLA2 and prothrombin gene 20210 G/A polymorphisms on stroke risk.

Summary:

• The study analyzed 173 healthy donors and 234 stroke patients using polymerase chain reaction.
• PLA1/PLA2 prevalence was 23.5% in healthy individuals (higher than other European countries) and 30.4% in stroke patients.
• Heterozygous PLA was more common in stroke patients over 50. Combined PLA and Factor II polymorphisms showed a significant increase in stroke cases (OR: 7.0).
• Carotid stenosis with polymorphism emerged as a risk factor for young stroke patients.

Impact:

• This research provides the first Hungarian data on platelet glycoprotein IIb/IIIa (LeuPro 33) polymorphism in stroke.
• Identifies potential genetic risk factors for stroke, particularly in specific age groups and in conjunction with other polymorphisms.
• Highlights the increased risk associated with combined genetic factors and carotid stenosis, informing future risk stratification strategies.
