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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 6 uncertain in NM_000128.4

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 47 curated pathogenic missense variants (we use a threshold of 10). The gene has 7 curated benign missense variants. Gene score misZ: 0.019886 (below the threshold of 3.09). Trascript score misZ: 0.83889 (below the threshold of 3.09). GenCC associations: The gene is linked to congenital factor XI deficiency.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.972

Variant summary: F11 c.1541G>T (p.Cys514Phe) 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 was absent in 251442 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1541G>T has been reported in the literature in at-least one heterozygous individual affected with factor XI deficiency disease (example: Gueguen_2012). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 22159456). ClinVar contains an entry for this variant (Variation ID: 68183). Based on the evidence outlined above, the variant was classified as uncertain significance.
