Genes affected
F11 (HGNC:3529): (coagulation factor XI) 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]

F11-related condition Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Aug 12, 2023 | The F11 c.1075delA variant is predicted to result in a frameshift and premature protein termination (p.Ile359Tyrfs*13). This variant has been reported in the compound heterozygous state in individuals with Factor XI deficiency (reported as 1072delA in Ventura et al. 2000. PubMed ID: 11127865; Zucker et al. 2007. PubMed ID: 18024374). This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-187201670-TA-T). Frameshift variants in F11 are expected to be pathogenic. This variant is interpreted as pathogenic. - |
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 04, 2024 | This sequence change creates a premature translational stop signal (p.Ile359Tyrfs*13) in the F11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in F11 are known to be pathogenic (PMID: 23929304). This variant is present in population databases (rs756604165, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with clinical features of autosomal recessive factor XI deficiency (PMID: 11127865, 18024374). This variant is also known as 1072delA. ClinVar contains an entry for this variant (Variation ID: 188727). For these reasons, this variant has been classified as Pathogenic. - |
