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]

F11 Gene-Disease associations (from GenCC):

• congenital factor XI deficiency

  Inheritance: AR, AD, SD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), Orphanet, ClinGen

ACMG classification

Our verdict: Pathogenic. The variant received 15 ACMG points.

• PM1: In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_000128.4
• 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, 0.996
• PP5: Variant 4-186271719-T-C is Pathogenic according to our data. Variant chr4-186271719-T-C is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 11901.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
