F11
protein-codingcoagulation factor XI
Gene summary
This gene encodes coagulation factor XI of the blood coagulation cascade. This protein is present in plasma as a zymogen, which is a unique plasma coagulation enzyme because it exists as a homodimer consisting of two identical polypeptide chains linked by disulfide bonds. During activation of the plasma factor XI, an internal peptide bond is cleaved by factor XIIa (or XII) in each of the two chains, resulting in activated factor XIa, a serine protease composed of two heavy and two light chains held together by disulfide bonds. This activated plasma factor XI triggers the middle phase of the intrisic pathway of blood coagulation by activating factor IX. Defects in this factor lead to Rosenthal syndrome, a blood coagulation abnormality. [provided by RefSeq, Jul 2008]

The relationship between F11 and congenital factor XI deficiency inherited in the autosomal recessive and dominant patterns has been evaluated using the ClinGen Clinical Validity Framework as of November, 2018. This association was made using case-level and experimental data. More than a 100 pathogenic variants in this gene are reported in humans, ranging from whole gene deletions, partial deletions and duplications, nonsense, frameshift, missense and splicing variants. Congenital Factor XI deficiency is characterized by a bleeding diathesis, diagnosed by a prolonged aPTT but normal PT and reduced factor XI activity and antigen levels. Mutations in F11 were first associated with this disease in humans as early as 1989 by Asakai et al. (PMID: 2813350). Summary of Case Level Data (12 points): The association is seen in at least 10 probands in 5 publications (PMID: 15026311, 15953011, 15180874, 21649796, 2813350, 22159456). More case-level evidence is available in the literature, but the maximum score for genetic evidence (12 pts) has been reached. The mechanism for disease has been reported to be biallelic loss of function as well as a dominant negative effect (PMID: 15026311, 2813350). Summary of Experimental Data (4.5 points): FXI activates FIX in the blood coagulation pathway (PMID: 3286010). Mouse and cattle models are reported that recapitulate FXI deficiency (PMID: 15566468, 9518045). In Holstein cows, FXI deficiency is naturally occurring and leads to bleeding symptoms. The deficiency is also reported in dogs (PMID: 5166932). In summary, the F11-Congenital FXI 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. This classification was approved by the ClinGen Hemostasis/Thrombosis GCEP on October 23, 2019 (SOP Version 6).
Clinical Genomic Database (CGD)
Manifestation: Hematologic
Intervention: Hematologic; Pharmacogenomic
Rationale: Individuals may be at risk of bleeding (eg, following surgery or with injury, and during delivery), and prophylaxis and preventive measures (eg, including avoidance of aspirin) and prompt treatment (eg, with fresh frozen plasma) may be beneficial, including considerations prior to/during pregnancy; Antifibrinolytic therapy may be beneficial in females with menorrhagia
Comments: Heterozygotes may have manifestations that warrant interventions

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_000128.4. 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.
