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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: F11 c.1853T>G (p.Ile618Ser), also reported as I600S, results in a non-conservative amino acid change located in the Serine proteases, trypsin domain (IPR001254) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251404 control chromosomes. c.1853T>G has been reported in the literature in the heterozygous state in 2 individuals and in the homozygous state in 1 individual affected with Hereditary factor XI deficiency disease (example, Mitchell_2005, Hill_2005). These data indicate that the variant is likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in <10% of normal FXI:C coagulant activity in the homozygous state and 23-60% FXI:C coagulant activity in the heterozygous state (example, Mitchell_2005, Hill_2005), consistent with possible dominant negative effects. The following publications have been ascertained in the context of this evaluation (PMID: 15953011, 16835901). ClinVar contains an entry for this variant (Variation ID: 68190). Based on the evidence outlined above, the variant was classified as pathogenic. -

Significance:Pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The F11 c.1853T>G variant is predicted to result in the amino acid substitution p.Ile618Ser. This variant, also referred to as c.1896T>G (p.Ile600Ser), has previously been reported to be causative for Hemophilia C (see patient IDs 033061 and 5964 in Mitchell et al. 2006. PubMed ID: 16835901; family 12 in Hill et al. 2005. PubMed ID: 15953011). In Mitchell et al., patient 033061 was homozygous for the c.1853T>G variant and exhibited <2% normal FXI protein activity compared to patient 5946 which was heterozygous for the variant and exhibited 23% FXI activity. Acquired disease states including liver disease, may also alter FXI activity. This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
