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]

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0103 - Dominant negative and loss of function are known mechanisms of disease in this gene and are associated with factor XI deficiency. Dominant negative missense variants tend to have dominant inheritance patterns (PMID:15026311), while loss of function variants are generally recessive, though symptomatic carriers have been reported (OMIM). (I) 0108 - This gene is associated with both recessive and dominant disease. Recessive cases are more severe than cases involving heterozygous carriers, who may be asymptomatic despite having FXI deficiency (PMID:18446632). (I) 0115 - Variants in this gene are known to have variable expressivity. There is a high degree of variable expression. Intrafamilial variation has been reported (PMID: 32118380). (I) 0200 - Variant is predicted to result in a missense amino acid change from threonine to methionine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 (10 heterozygotes, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v3) (1 heterozygote, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0600 - Variant is located in the annotated trypsin domain (DECIPHER). (I) 0710 - Another missense variant comparable to the one identified in this case has inconclusive previous evidence for pathogenicity. This alternative change (p.(Thr593Ala)) has been reported as a VUS (ClinVar). (I) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been reported as likely pathogenic and pathogenic (ClinVar, LOVD), and observed in heterozygous, homozygous and compound heterozygous individuals with F11 deficiency (PMID: 15749683; PMID: 14717969, PMID: 16835901, PMID: 31064749, PMID: 37252892). (SP) 1002 - This variant has moderate functional evidence supporting abnormal protein function. Transfected BHK-570 cells have shown this variant results in reduced enzyme activity (PMID: 17549289). (SP) 1206 - This variant has been shown to be paternally inherited (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 593 of the F11 protein (p.Thr593Met). This variant is present in population databases (rs145906668, gnomAD 0.01%). This missense change has been observed in individuals with autosomal recessive factor XI deficiency (PMID: 14717969, 15749683, 27067486). It has also been observed to segregate with disease in related individuals. This variant is also known as T575M. ClinVar contains an entry for this variant (Variation ID: 371214). 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 with a positive predictive value of 95%. Experimental studies have shown that this missense change affects F11 function (PMID: 17549289). For these reasons, this variant has been classified as Pathogenic. -
