General information
Haemophilia B in cats (also known as ‘Christmas Disease’) is a group of rare hereditary bleeding disorders in which blood doesn’t clot appropriately in case of an injury. Haemophilia B is a severe condition that can be inborn or acquired. Haemophilia B is an X chromosome-linked recessive deficiency of coagulation factor IX (F9).
The variant analysed here is one of two known mutations that causes Haemophilia B in cats.
Clinical features
Cats with Haemophilia often show weakness, fever and lack of appetite. Furthermore lameness and swelling of the joints may occur due to spontaneous bleeding into the joints. Internal bleeding in organs or body cavities can contribute to bloody or dark stool and vomit, rectal or vaginal bleeding, nose bleeding and swellings under the skin.
Additional information
This test is based on the TGT to TAT mutation.
