F7
protein-codingcoagulation factor VII, the group of Gla domain containing
Gene summary
This gene encodes coagulation factor VII which is a vitamin K-dependent factor essential for hemostasis. This factor circulates in the blood in a zymogen form, and is converted to an active form by either factor IXa, factor Xa, factor XIIa, or thrombin by minor proteolysis. Upon activation of the factor VII, a heavy chain containing a catalytic domain and a light chain containing 2 EGF-like domains are generated, and two chains are held together by a disulfide bond. In the presence of factor III and calcium ions, the activated factor then further activates the coagulation cascade by converting factor IX to factor IXa and/or factor X to factor Xa. Defects in this gene can cause coagulopathy. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar proteolytic processing to generate mature polypeptides.

F7 was reported in relation to autosomal recessive Factor VII deficiency as early as 1996 (Arbini et al., PMID: 8652821). More than 100 pathogenic variants in this gene are reported in humans, ranging from deletions and duplications, nonsense, frameshift and splicing variants to a number of functionally-characterized missense variants. Factor VII deficiency is characterized by a bleeding diathesis, with an increased prothrombin time, but normal activated partial thromboplastin time, reduced Factor VII activity and antigen levels. Summary of Case Level Data (12 points): Variants in this gene are reported in at least 9 probands in 6 publications (PMIDs: 8652821, 11091194, 22628013, 10959697, 23141848, 11529858). More case-level evidence is available in the literature, but the maximum score for genetic evidence has been reached. The mechanism for disease is homozygous loss of function. Summary of Experimental Data (4.5 points): FVII is involved in the blood coagulation pathway and functions to activate FX in complex with Tissue Factor (PMID: 3286010). Mouse models recapitulate the human bleeding phenotype, but bleeding is more severe in mice (PMID: 9384381). AAV-mediated expression of FVII is shown to rescue bleeding in dog models (PMID: 26702064). In summary, the F7-Factor VII deficiency gene-disease relationship is Definitive. This has been repeatedly demonstrated in both the research and clinical diagnostic settings, and has been upheld over time.

Manifestation: Hematologic
Intervention: Hematologic; Pharmacogenomic
Rationale: Individuals can suffer from bleeding diatheses of varying severity, and preventive measures and prompt treatment (including with factor replacement therapy) related to bleeding episodes can be beneficial; Precautions should be taken related to certain agents that may provoke/worsen bleeding risk

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_019616.4. Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

- Function
- FUNCTION: 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.;
- Disease
- DISEASE: Factor VII deficiency (FA7D) [MIM:227500]: A hemorrhagic disease with variable presentation. The clinical picture can be very severe, with the early occurrence of intracerebral hemorrhages or repeated hemarthroses, or, in contrast, moderate with cutaneous-mucosal hemorrhages (epistaxis, menorrhagia) or hemorrhages provoked by a surgical intervention. Finally, numerous subjects are completely asymptomatic despite very low factor VII levels. {ECO:0000269|PubMed:10862079, ECO:0000269|PubMed:11091194, ECO:0000269|PubMed:11129332, ECO:0000269|PubMed:12472587, ECO:0000269|PubMed:14717781, ECO:0000269|PubMed:1634227, ECO:0000269|PubMed:18976247, ECO:0000269|PubMed:19432927, ECO:0000269|PubMed:19751712, ECO:0000269|PubMed:2070047, ECO:0000269|PubMed:21206266, ECO:0000269|PubMed:21372693, ECO:0000269|PubMed:26761581, ECO:0000269|PubMed:7974346, ECO:0000269|PubMed:7981691, ECO:0000269|PubMed:8043443, ECO:0000269|PubMed:8204879, ECO:0000269|PubMed:8242057, ECO:0000269|PubMed:8364544, ECO:0000269|PubMed:8652821, ECO:0000269|PubMed:8844208, ECO:0000269|PubMed:8883260, ECO:0000269|PubMed:8940045, ECO:0000269|PubMed:9414278, ECO:0000269|PubMed:9452082, ECO:0000269|PubMed:9576180}.
