مستخلص: | 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 a young age. The recent isolation of protein S cDNA has enabled us to start a search for genetic defects in the protein S gene of heterozygotes. Using Southern blotting on probands of six unrelated families with hereditary protein S deficiency, one proband was found to have a grossly abnormal gene pattern. The abnormality appears to involve at least the deletion of the middle portion of the protein S coding sequence. Family analysis showed that the defect cosegregates with the protein S deficiency. These data agree with the notion that hereditary thrombophilia associated with protein S deficiency is indeed directly the result of a defect in the protein S gene. |
