Human coagulation factor Ⅶ,FⅦ ELISA Kit

Initiates the extrinsic pathway of blood coagulation. Serine protease that circulates in the blood in a zymogen form. Factor VII is converted to factor VIIa by factor Xa, factor XIIa, factor IXa, or thrombin by minor proteolysis. In the presence of tissue factor and calcium ions, factor VIIa then converts factor X to factor Xa by limited proteolysis. Factor VIIa will also convert factor IX to factor IXa in the presence of tissue factor and calcium.

9. A common pathogenic mechanism, possibly a defective folding of the mutant proteins, was triggered by the FVII mutations. The misfolded state led to impaired trafficking of these proteins causing Endoplasmic reticulum retention, which would explain the low to very low FVII plasma levels observed in patients carrying these mutations. PMID: 29246447
10. FVIIa-antithrombin but not FVIIa is a ligand for LRP1, and LRP1 contributes to the clearance of FVIIa-antithrombin in vivo PMID: 27614059

16. Large deletions play a minor but essential role in the mutational spectrum of the F7 and F10 genes. Copy number analyses (e. g. MLPA) should be considered if sequencing cannot clarify the underlying reason of an observed coagulopathy. Of note, in cases of combined FVII/FX deficiency, a deletion of the two contiguous genes might be part of a larger chromosomal rearrangement. PMID: 26540129
17. Holders of the R allele had significantly higher activity of coagulation factor F7 (97.66 +/- 15.48 against 83.37 +/- 15.16, p = 0.002) and factor F2 (107.45 +/- 6.03 against 103.75 +/- 6.81, p = 0.023) than holders of the Q allele PMID: 27215039

20. The story of FVII well summarizes the efforts of both theoretical and clinical approaches in the characterization of a coagulation disorder, that is, among the rare bleeding conditions, most frequently encountered in clinical practice. PMID: 25973586
21. Identified are the FVII gene mutations in the Chinese Han population of four unrelated FVII-deficient patients, and the effect of these mutations on the function of FVII molecule level has also been elucidated. PMID: 25767893
