Recombinant Human Antithrombin-III (SERPINC1)

1. Molecular analysis may be the best method to identify antithrombin deficiency. Up to 80% of patients with antithrombin deficiency have SERPINC1 gene defects, mostly (90% of the 315 gene defects described so far) point mutations or small deletions or insertions affecting the 7 exons or flanking regions. [review] PMID: 30005274
2. Laboratory tests and direct sequencing of PROC and SERPINC1 were conducted for the patient and his family members. Coagulation tests revealed that the patient presented type I antithrombin deficiency combined with decreased protein C activity resulting from a small insertion mutation c.848_849insGATGT in SERPINC1 and a short deletion variant c.572_574delAGA in PROC. PMID: 28861852
3. Thirty-one members of a single family were included. Clinical data was collected regarding thrombotic history. The mutation was identified by direct sequencing of the SERPINC1 gene. HEK293 cells were transfected with wild type and mutant SERPINC1 plasmids. PMID: 28783511

6. Report high levels of latent antithrombin in plasma from patients with antithrombin deficiency caused by mutations affecting the stability of the native conformation. PMID: 28229161
7. Study identified one new small deletion within AT, which results in the loss of four amino acids (INEL) and is located at strand 3 of beta-sheet A, a region highly conserved in SERPINC1. This mutation leads to type I AT deficiency by promoting the intracellular retention of AT, which induces ER stress. PMID: 27708219
8. It was our aim to identify mutations in SERPINC1 causing transient antithrombin deficiency. SERPINC1 was sequenced in 214 cases with a positive test for antithrombin deficiency, including 67 with no deficiency in the sample delivered to our laboratory. The p.Val30Glu mutation (Antithrombin Dublin) was identified in five out of these 67 cases, as well as in three out of 127 cases with other SERPINC1 mutations. PMID: 27098529

15. Nine patients (1.8%), [5% in arterial thrombosis and 0.8% in venous thrombosis] showed a missense variant in exon 5 i.e. p.Pro305His (c.1033 C > A); none of these patients showed the presence of any other variations in the gene. PMID: 27161325

17. Our studies of ATIII in-cell folding reveal a surprising, biased order of disulfide bond formation, with early formation of the C-terminal disulfide, before formation of the N-terminal disulfides, critical for folding to the active, metastable state PMID: 27222580

20. The present study highlights that AT physiological activities are strictly controlled not only by a core fucose at the reducing end but also by the high-mannose-type structures at the nonreducing end. The beta-form with the immature high-mannose type appears to function as a more potent anticoagulant than the AT typically found in human plasma, once it emerges in the blood. PMID: 26747427
