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]

Variant summary: F11 c.1693G>A (p.Glu565Lys) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. One study reported that this variant causes skipping of exon 14 however the results as presented do not allow a conclusive determination supporting this conclusion (Zucker_20011). The variant was absent in 251488 control chromosomes. c.1693G>A has been reported in the literature as a non-informative genotype (second allele not specified), a homozygous genotype (one report) and as a presumed compound heterozygous genotype (one report) in individuals affected with features of factor XI deficiency disease or in settings of multigene panel testing for coagulation disorders (example, Hill_2005, Qulin_2009, Karimi_2009, Zucker_2011, Rimoldi_2018, Downes_2019). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 31064749, 15953011, 18758779, 20523169, 29178608, 21718436). One group has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic. -
