NEW TEST FOR DWARFISM AVAILABLE
A new genetic test for a form of dwarfism in miniature horses is now available from the University of Kentucky’s Animal Genetic Testing and Research Laboratory.
The test identifies carriers of four mutations in the aggrecan gene, which contains proteins critical to the development of cartilage structures. The mutations may result in a range of physical issues, including respiratory problems, oral malformations and abnormal bone growth.
Researchers say carriers of the mutated gene may not exhibit any outwards signs, but when two carriers are mated, the result can be a foal affected with any combination of the genes, some of which are lethal.
The new test does not identify all forms of dwarfism in Miniature Horses or forms found in other breeds. For more information about the test, visit the laboratory’s website or call 859-218-1193.

If people refuse to stop breeding horses with the gene there is no excuse not to have your breeding stock tested so dwarf foals won’t be produced. Horses with the gene should never be bred, but realistically there are people who don’t care, and at least this test might make people more aware of what’s in their stock so crossing of two carriers can be avoided.
