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.

Species-specific name: Hereditary factor XI deficiency; congenital factor XI deficiency

Species-specific symbol: FXI

Inheritance: Genotypes for the V516M variant (OMIA variant 1472) and available pedigree information were consistent with autosomal recessive inheritance (Kuder et al., 2022).

Molecular basis: Kuder et al. (2022) discovered a "common missense variant FXI-V516M [that] causes a cross-reactive material positive FXI deficiency in MCCs [Maine Coon cats] that is associated with mild-moderate bleeding tendencies".

Clinical features: Clinical signs of abnormal haemostasis may include unexplained and abnormal bleeding, anaemia, bruising easily, gingival bleeding, prolonged bleeding following dental extractions, development of hematomas without apparent trauma, and excessive peri-operative bleeding (Troxel et al., 2002; Renné et al., 2009; Kuder et al., 2022) IT thanks DVM student Mo’Ath Ayish, who provided the basis of this contribution in May 2023.

Pathology: Pathological features may include prolonged bleeding time and activated partial thromboplastin time (aPTT) and reduced plasma FXIa levels (Kuder et al., 2022). IT thanks DVM student Mo’Ath Ayish, who provided the basis of this contribution in May 2023.

Breeds: Domestic Shorthair, Maine Coon (Cat) (VBO_0100154).

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.
