title: Is Gas6 protein associated with sticky platelet syndrome?
abstract: The aim of this study was to detect the prevalence of the polymorphisms of growth arrest-specific gene 6 (Gas6; Gas6 c. 834 + 7G > A) in patients with sticky platelet syndrome (SPS). Sticky platelet syndrome is a hereditary, autosomal dominant thrombophilia characterized by platelet hyperaggregation after low concentrations of platelet inducers-adenosine diphosphate (ADP) and epinephrine (EPI). The cause of SPS still remains unknown, but in recent years it was suggested that Gas6 protein may have a potential role in the pathogenesis of SPS. To assess the Gas6 polymorphisms (Gas6 c. 834 + 7G > A), 128 patients with SPS were included in the study and examined by polymerase chain reaction (PCR) method. GG genotype was detected in 63 (49.2%) patients, GA genotype in 53 (41.4%) patients, and AA genotype in 12 (9.4%) patients. The results in controls did not differ significantly compared to patients with SPS. Our findings did not prove allele A to be less associated with thrombosis and that ''prothrombotic'' allele G may be associated with higher risk of thrombosis. We cannot support the idea that Gas6 protein and Gas6 polymorphisms may be associated with thrombosis in SPS.
