Fig. 1From: Identification and characterization of two SERPINC1 mutations causing congenital antithrombin deficiency(a–b) Two pedigree profiles of hereditary antithrombin deficiency. (c) Computed tomographic angiography (CTA) findings of the small bowel mesenteric vessels in proband (III1) of Pedigree A showed thrombosis in the inferior vena cava, left common iliac vein, external iliac vein, and left external iliac vein. (d–e) Digital subtraction angiography findings of the proband (III1) in Pedigree B showed thrombosis of the right superficial femoral vein-common femoral vein and distal right external iliac vein. (f) A heterozygous mutation SERPINC1 c.1377delC: p.Asn460Thrfs*20 was found in the proband of Pedigree A (III1). (g) Wild-type at c.1377C. (h) A heterozygous mutation SERPINC1 c.685C > T: p. (Arg229*) was found in the proband of Pedigree B. (i) Wild-type of c.685CBack to article page
