A1/A2 polymorphism of GpIIIa gene and a risk of aneurysmal subarachnoid haemorrhage.
2009
Abstract Platelet glycoproteins are involved in pathophysiology of cerebrovascular diseases. The aim of this study was to investigate the association between the GpIIIa gene A1/A2 polymorphism and a risk of aneurysmal subarachnoid haemorrhage (SAH) in a Polish population. In a case-control study we genotyped 288 Caucasian patients with aneurysmal SAH and 457 age-, gender- and race-matched controls. The GpIIIa A1/A2 polymorphism was genotyped with RFLP technique. No difference was found in the distribution of the polymorphism between the cases and controls (cases: A1A1—201 (69.8%), A1A2—83 (28.8%) and A2A2—4 (1.4%) vs. controls: A1A1—323 (70.7%); A1A2—128 (28.0%); A2A2—6 (1.3%), P > 0.05. In a multivariate analysis female gender (OR = 1.950; 95%CI: 1.308–2.907), hypertension (OR = 4.774; 95%CI: 3.048–7.478) and smoking (OR = 2.034; 95%CI: 1.366–3.030), but not GpIIIa A1/A2 polymorphism, were independent risk factors for aneurysmal SAH. The GpIIIa A1/A2 polymorphism is not a risk factor of aneurysmal SAH in a Polish population.
