Genetic Disorders

Of the many genetic disorders in the world, there are thousands that affect animals.  Of those that affect animals, many affect horses and some are breed specific. 

There are four genetic conditions specific to Arabian horses which usually result in death or euthanasia of an affected animal.  These are:      
~  Severe Combined Immunodeficiency Disorder (SCID) (test available)
~  Cerebellar Abiotrophy (CA) (test available)
~  Lavender Foal Syndrome (LFS) (test available)
~  Occipital Atlanto-Axial Malformation (OAAM) (test not yet available)

Testing for SCID, CA and LFS is available to horse owners in Australia.

Stallions - The AHSA has implemented the compulsory testing of Arabian stallions standing at stud.

Mares - Before any foal born after 1/8/2016 out of an Arabian mare born after 1/8/2000 can be registered, the mare must have SCID, LFS and CA results on file if her registration number ends in 1, 2, 3, 4 or 5.
From 1/8/2017 all Arabian mares born after 1/8/2000 (ie. the remaining whose registration numbers end in 6, 7, 8, 9 or 0) will also require such results on file. Compulsory testing of all stallions and mares will be being introduced in the future. 

Please note that the results of this testing will not alter the eligibility of these stallions and mares offspring.

These tests should be used as tools by responsible owners and breeders when planning breedings as carrier horses can be safely bred to clear horses.  Breeders are then able to retain quality traits and crosses with the knowledge that their decisions will result in producing unaffected foals.

The World Arabian Horse Organisation has published an article "Genetic Disorders in Arabian Horses" which is very informative. You can read the article here. 

If you wish to test your horses for any or all of these conditions, then please go to our Forms Page and apply for a Kit now.
