DNA Identification of Feline Blood Types

The Winn Feline Foundation has announced the
identification of the DNA mutations that cause the A and B
blood types of the domestic cat.

The international research team included investigators
from the University of California-Davis School of Veterinary
Medicine, Istituto di Zootecnica - Vetogene Laboratory,
School of Veterinary Medicine, University of Milan.  

Specific mutations have
been shown to be 100% concordant with the type A and
type B blood groups from cats of various breeds, including
Birman, British Shorthair, Devon Rex, and Ragdoll from the
United States and Europe. The causative mutation for the
third blood type, the rare type AB, remains to be identified,
although the research suggests it to be a novel third allele.

Breeders will now be able to identify the major blood
groups of the cat with a simple buccal swab test, as well as
identification of cats that carry the recessive type B. The
U.C. Davis Veterinary Genetics Laboratory is offering the
new test.
