A clotting defect in an Arab colt foal
Equine Veterinary Journal
|January 1, 1977
Summary
A rare multiple clotting defect was found in a young foal due to deficiencies in blood clotting Factors VIII, IX, and XI. Genetic testing revealed no clotting factor abnormalities in the foal
Area of Science:
- Veterinary Hematology
- Equine Genetics
- Coagulation Disorders
Background:
- Coagulation defects can cause severe bleeding in foals.
- Genetic factors are often implicated in inherited bleeding disorders.
Purpose of the Study:
- To describe a case of multiple clotting factor deficiency in an equine foal.
- To investigate the genetic basis of the clotting defect.
Main Methods:
- Coagulation factor assays were performed on the affected foal.
- Family members (sire, dam, half-siblings) were tested for clotting factor abnormalities.
Main Results:
- The foal exhibited deficiencies in Factors VIII, IX, and XI.
- No clotting factor deficiencies were identified in the foal's parents or siblings.
Conclusions:
- This case highlights a potential inherited multiple clotting factor deficiency in Arab foals.
- Further research is needed to identify the specific genetic mutation responsible.
