Insights
Hereditary antithrombin deficiency, a rare blood clotting disorder, can cause cerebral vein thrombosis (CVT). This study highlights its occurrence in three family members, emphasizing genetic testing and lifelong anticoagulation for affected individuals.
Area of Science:
- Genetics
- Hematology
- Neurology
Background:
- Hereditary antithrombin (AT) deficiency is a rare genetic disorder increasing thrombophilia risk.
- Cerebral vein thrombosis (CVT) is a serious condition associated with thrombophilia.
- Identifying genetic thrombophilia is crucial for managing anticoagulation and preventing venous thromboembolism (VTE).
Abstract:
Hereditary antithrombin (AT) deficiency is a rare thrombophilia associated with cerebral vein thrombosis (CVT). We report a case study of hereditary AT deficiency causing CVT in three members of a family. A 29-year-old female presented with features of CVT. Her mother and a sister had CVT in the past and investigation for hereditary thrombophilia revealed low blood AT activity in all of them. The index patient (proband) was positive for the SERPINC1 gene mutation confirming the diagnosis of hereditary AT deficiency. She recovered well with anticoagulation and was advised to continue it lifelong. Diagnosing hereditary thrombophilia like AT deficiency is important in planning anticoagulation and proper counseling of asymptomatic family members regarding prophylaxis for venous thromboembolism (VTE) in high-risk situations.
