摘　　要：BACKGROUND The hereditary antithrombin(AT)deficiency caused by SERPINC1 gene mutation is an autosomal dominant thrombotic disorder.An increasing number of studies have shown that mutations in the SERPINC1 rs2227589 polymorphic site are correlated with a risk of venous thromboembolism(VTE)at common sites,such as lower extremity deep venous thrombosis and pulmonary thromboembolism.Currently,there are no reports of cerebral venous sinus thrombosis(CVST),a VTE site with a low incidence rate and rs2227589 polymorphism.CASE SUMMARY Here,we report a Chinese CVST case with a mutation of the SERPINC1 rs2227589 polymorphic site,which did not cause significant AT deficiency.In a 50-year-old male patient presenting with multiple cerebral venous sinus thromboses no predisposing factors were detected,although a relative had a history of lower extremity deep venous thrombosis.We performed sequencing of the SERPINC1 gene for the patient and his daughter,which revealed the same heterozygous mutation at the rs2227589 polymorphic site:c.41+141G>A.CONCLUSION The results showed that more studies should be conducted to assess the correlation between rs2227589 polymorphism and CVST.
