Antithrombin (AT) deficiency is a blood disorder associated with an increased tendency to form thrombosis. Hereditary AT deficiency is frequently caused by mutations in SERPINC1 gene. It is usually inherited as an autosomal dominant with variable penetrance. Homozygous pathogenic mutations in this gene are extremely rare. We present a case of a 7-year-old female who presented at age of 4 years with massive cerebral sinus venous thrombosis. Thrombophilia workup showed a low AT level of 30%. Targeted genetic sequencing of SERPINC1 revealed a novel pathogenic homozygous mutation c.1320C>G p. (Phe440Leu). The patient was managed initially with unfractionated heparin with AT replacement using fresh frozen plasma and was later switched to only low-molecular-weight heparin. There was no recurrence or new thrombosis with 3 years of follow-up. |
