Mutations in SERPINC1 lead to deficiency in antithrombin (AT) which is an endogenous anticoagulant of normal hemostasis and could result in venous thromboembolism (VTE).
A 61-year-old male patient with recurrent thrombosis returned to the hospital with multiple cerebral thrombosis after voluntary cessation of dabigatran therapy. Laboratory tests revealed a type I AT deficiency in this patient and further whole exome sequencing (WES) identified a novel heterozygous frameshift duplication (c.233_236dup, p.Val80Alafs*26) in SERPINC1 gene. Long-term dabigatran treatment was given and no recurrence or side effects were found within the followed 5 years.
A multisystem VTE patient with a novel SERPINC1 mutation (c.233_236dup, p.Val80Alafs*26) reached a favourable outcome after dabigatran treatment.
SERPINC1基因的突变导致抗凝血酶(AT)缺乏,抗凝血酶是正常止血过程中的一种内源性抗凝剂,可导致静脉血栓栓塞(VTE)。
一名61岁复发性血栓形成的男性患者,在自愿停止达比加群治疗后因多发性脑血栓再次入院。实验室检查显示该患者为I型抗凝血酶缺乏,进一步的全外显子组测序(WES)在SERPINC1基因中发现了一种新的杂合移码重复突变(c.233_236dup,p.Val80Alafs*26)。给予患者长期达比加群治疗,在随后的5年中未发现复发或副作用。
一名患有新型SERPINC1突变(c.233_236dup,p.Val80Alafs*26)多系统静脉血栓栓塞患者在接受达比加群治疗后取得了良好的疗效。
