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

Verdict is Pathogenic. Variant got 18 ACMG points.

• PS1: Transcript NM_000128.4 (F11) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a domain Apple 2 (size 83) in uniprot entity FA11_HUMAN there are 5 pathogenic changes around while only 0 benign (100%) in NM_000128.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.995
• PP5: Variant 4-186274209-G-A is Pathogenic according to our data. Variant chr4-186274209-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 68193.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr4-186274209-G-A is described in Lovd as [Pathogenic].

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Apr 14, 2023	This variant is present in population databases (rs281875256, gnomAD 0.002%). For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt F11 protein function. ClinVar contains an entry for this variant (Variation ID: 68193). This variant is also known as p.Cys122Tyr. This missense change has been observed in individuals with autosomal recessive factor XI (FXI) deficiency (PMID: 16607084, 18515884, 19718484, 24112640). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 140 of the F11 protein (p.Cys140Tyr). -
