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 p.Thr150Met variant in F11 has been reported in one heterozygous individual and one compound heterozygous individual both with Factor XI defieciency (Mitchell 2006 PMID: 16835901, Saunders 2009 PMID: 19652879), and Factor XI assays for both individuals showed dimished activity. The variant has been in 0.02% (1/4828) South Asian chromosomes by gnomAD (https://gnomad.broadinstitute.org/); however this frequency is low enough to be consistent with a carrier frequency for pathogenic F11 variants. Computational prediction tools and conservation analysis suggest that the p.Thr150Met variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal dominant Factor XI deficiency.
