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 F11 c.1716+1G>A variant occurs in a canonical splice site (donor) and is therefore predicted to disrupt or distort the normal gene product. The c.1716+1G>A variant has been described as a founder mutation in the Ashkenazi Jewish population (Peretz et al. 2013). The c.1716+1G>A variant has been reported in three studies and was found in a total of 30 probands from 14 families of Ashkenazi Jewish descent and one family of unknown ethnicity with factor XI deficiency, including in one in a homozygous state, in 12 in a compound heterozygous state, and in 17 in a heterozygous state (Asakai et al. 1989, Mitchell et al. 2006, Peretz et al. 2013). The c.1716+1G>A variant was shown to segregate with the disease in two studies and was absent from 491 healthy Ashkenazi Jewish controls (Asakai et al. 1989, Peretz et al. 2013). The variant is reported at a frequency of 0.000406 in the Ashkenazi Jewish population of the Genome Aggregation Database. Based on the evidence and the potential impact of splice donor variants, the c.1716+1G>A variant is classified as pathogenic for Factor XI deficiency. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

This sequence change affects a donor splice site in intron 14 of the F11 gene. While this variant is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product. This variant is present in population databases (rs373297713, gnomAD 0.04%). Disruption of this splice site has been observed in individual(s) with Factor XI deficiency (PMID: 2813350, 16835901, 23332144). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 11890). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant disrupts a region of the F11 protein in which other variant(s) (p.Thr593Met) have been observed in individuals with F11-related conditions (PMID: 15749683, 27067486). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
