Cross-species summary: Congenital factor XI deficiency / F11 deficiency is an inherited bleeding disorder characterized by reduced levels and activity of factor XI (FXI) resulting in moderate bleeding symptoms, usually occurring after trauma or surgery. [Orphanet : 329] The disease is also called plasma thromboplastin antecedent (PTA) deficiency, haemophilia C, or Rosenthal syndrome.

Molecular basis: A molecular basis for this disorder was first reported by Tcherneva et al. (2007): "the 7th coding exon differs between normal and affected animals. It is normally 110 bp long, but in affected KBTs it contains a short interspersed nucleotide element (SINE) insertion. This exonic SINE is 90 bp long, consisting mostly of adenines coding for lysine which is presumed to affect the 3rd apple domain of the FXI gene."

Clinical features: Congenital Factor XI deficiency is characterised by abnormal haemostasis and excessive bleeding, usually following trauma or surgery. Clinical signs of abnormal haemostasis and excessive bleeding include bruising, epistaxis, and menorrhagia (Fogh and Fogh, 1988). Affected dogs have significantly decreased Factor XI activity levels (less than 10%), heterozygous/carrier dogs have decreased Factor XI activity levels, (25-50%) but appear to be asymptomatic (Fogh and Fogh, 1988).

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
