Generell informasjon
Factor XII deficiency, also known as Hageman deficiency, is the most common congenital coagulopathy in domestic cats. Blood coagulation or clotting is regulated by a complex cascade of plasma proteins. This is an essential process that stops bleeding at the site of injury.
One of these key proteins is coagulation factor XII (also referred to as FXII, F12, or factor 12). Mutations in the F12 gene disrupt the normal function of FXII, leading to prolonged activated partial thromboplastin time (aPTT) and activated clotting time (ACT).
This test detects variant 147 that is associated with a moderate to severe decrease in FXII activity causing difficulties in blood coagulation. It is found widespread across many breeds. Meaning it more common than variant 533.
Kliniske egenskaper
This variant leads to FXII deficiency, resulting in the absence of detactable factor XII in the cat's blood plasma. Cats homozygous for this mutation have a severe deficiency and will likely have an increased tendency to bleeding after surgery or (minor) trauma. Cats that are heterozygous have a moderate reduction in FXII activity.
Tilleggsinformasjon
In literature an autosomal recessive inheritance pattern is suggested, but also describes mild clinical features in cats heterozygous for this variant.
If both variant 147 and 533 are present in heterozygous state, the animal will not produce any functional FXII protein. The cat will be considered as homozygous affected.
