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]

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with F11-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change creates a premature translational stop signal (p.Glu543*) 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). -
