Summary
A kindred with Type I protein S deficiency experienced skin necrosis during anticoagulant therapy for deep venous thrombosis. This highlights the variable clinical presentation of protein S deficiency within families.
Area of Science:
- Genetics
- Hematology
- Vascular Medicine
Background:
- Protein S deficiency is an inherited thrombophilia.
- Oral anticoagulant therapy is standard for deep venous thrombosis (DVT).
Observation:
- A family (kindred) with Type I protein S deficiency was studied.
- The index case developed skin necrosis during oral anticoagulant therapy for DVT.
Findings:
- Two additional family members were diagnosed with protein S deficiency.
- These cases illustrate the diverse clinical manifestations of this condition.
Implications:
- Early identification and genetic counseling are crucial for families with protein S deficiency.
- Understanding clinical variability aids in personalized DVT management strategies.
