Sorry, we aren't taking any more orders this week.
We are working on ways to expand our testing as well a few other projects. We have reduced the number of orders we take each week to make sure we have some time to make these improvements. These limits should be temporary! In a few months we will take off the brakes.
We will take more orders next week. Orders open on Monday, Sydney time. In the mean time, have a look through our individual tests and panels (panels are groups of tests) to help decide what you want to test for.
Cerebellar abiotrophy (CA)
CA can appear in pure- and part-bred Arabian, Australian Ponies and Welsh ponies and cobs. Horses affected by CA can show head tremors, problems with their balance, and exaggerated or erratic leg movements. The age where signs of CA appear and severity of the signs vary a lot. In the best cases, the horse appears normal for several years (or more, in at least one Australian case). In the worst cases an affected foal will be unable to stand without assistance after birth, and will need to be euthanased. Most cases fall between these two extremes, with signs appearing in a weanling or young horse that progressively worsen over a few months or years.
CA is an autosomal recessive disorder. Autosomal disorders are equally likely to affect male or female horses, while "recessive" means that a horse needs to inherit the CA mutation from both its sire and its dam to be affected.
