Cross-species summary: In humans also called Fletcher factor deficiency

Molecular basis: Okawa et al. (2011) "describe a case of a dog that was referred for neurological defects and had a prolonged activated partial thromboplastin time (aPTT) and normal prothrombin time (PT) with no hemostatic defects. By using human PK-deficient plasma, the dog was diagnosed to have PK deficiency. The nucleotide sequence of normal canine PK cDNA was determined and compared with the genomic sequences of PK in the affected dog. The comparison revealed that the dog had a point mutation in exon 8 that leads to an amino acid substitution in the fourth apple domain of PK."

Clinical features: Prekallikrein (PK) is a protein that is involved in the blood clotting process. As a result, dogs with a PK deficiency experience prolonged activated partial thromboplastin Time (aPPT) (Okawa et al., 2011). This disorder is often asymptomatic in the absence of other clotting factor deficiencies (Chin et al., 1986). Classical signs of haemostatic disorders such as haematuria and prolonged bleeding or healing times after surgery have been reported but are unlikely unless there is concurrent disease (Chinn et al. 1986). Gastrointestinal bleeding has also been reported in a dog with this disorder (Otto et al., 1991). IT thanks DVM student Eloise O’Connor, who provided the basis of this contribution in May 2023.

Breeds: Chinese Shar-Pei (Dog) (VBO_0200351), Shih Tzu (Dog) (VBO_0201223).

Variants

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.
