Familial thrombophilia, the hereditary predisposition to venous thromboembolic disease, is associated with a protein S deficiency in approximately 8% of the cases. Laboratory measurements of total protein S antigen in affected families have indicated that heterozygotes, ie, individuals carrying both a normal and a defective protein S gene, are severely at risk of developing venous thrombosis at...
Protein S is a natural anticoagulant present in the plasma that serves as a cofactor for activated protein C. Patients deficient in protein S are subject to recurrent venous thrombotic disease. Protein S deficiency differs from other plasma protein deficiencies in that deficient patients often have normal or only mildly reduced levels of protein S in their plasma as detected by conventional imm...
A family with a history of severe recurrent venous thromboembolic disease was studied to determine if a plasma protein deficiency could account for observed disease. Protein S levels in plasma were determined immunologically using the Laurell rocket technique. The propositus, his mother, his aunt, and his cousin who were clinically affected had 17% to 65% of the control levels of protein S anti...
ABSTRACT Thrombophilia is a clinical problem throughout the world and it is particularly a major problem in western countries. Factors causing thromboembolic diseases are numerous and they may be inherited or aquired. In order to investigate causes of venous thrombosis. The level of antithrombin (AT), protein C, protein S and the presence of antiphospholipid antibodies (APA) in 300 p...
