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 missense variants have been shown to have a dominant negative disease mechanism (PMID:15026311), whilst 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. Individuals with biallelic variants generally have a more severe phenotype. Heterozygous individuals 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, with intrafamilial variation reported (PMID: 32118380). (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.001 for a condition (10 heterozygotes, 0 homozygotes). (SP) 0701 - Other NMD predicted variants comparable to the one identified in this case have very strong previous evidence for pathogenicity (ClinVar). (SP) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been reported in multiple homozygous and compound heterozygous individuals with Factor XI deficiency including two unaffected homozygous probands (ClinVar, PMID: 14508802, 25681615, 27067486, 32464451, 32333264, 34799507). Among those, two unaffected heterozygous daughters of an affected proband also demonstrated reduced F11 activity (PMID: 14508802). (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 creates a premature translational stop signal (p.Tyr369*) in the F11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in F11 are known to be pathogenic (PMID: 23929304). This variant is present in population databases (rs773905328, gnomAD 0.04%). This premature translational stop signal has been observed in individual(s) with clinical features of autosomal recessive factor XI deficiency (PMID: 14508802, 25681615, 32220196). This variant is also known as Tyr351-->Term and p.Tyr351X. ClinVar contains an entry for this variant (Variation ID: 189115). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
