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]

The F11 c.1135+5G>A variant is predicted to interfere with splicing. This variant was reported in heterozygous state in two individuals with Factor XI deficiency (Mitchell et al. 2006. PubMed ID: 16835901; Duncan et al. 2008. PubMed ID: 18446632). This variant is predicted to induce a large splicing change (Xiong et al. 2015. PubMed ID: 25525159) and impact splicing based on splicing prediction programs (SpliceAI, Jaganathan et al. 2019. PubMed ID: 30661751). This variant is reported in 0.0031% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as likely pathogenic. -
