I have had Sassy & Storm DNA tested for Collie Eye Anomaly/Choroidal Hypoplasia (CEA/CH). This is a hereditary condition found in sheepdogs/collies which can cause blindness in its more severe cases. Our wee Sookie is affected by this condition. Sookie has mild CEA/CH. This means, when she gets older, her sight will deteriorate. It is unlikely Sookie will go blind.
Both Sassy & Storm were diagnosed clear by a Opthalmic Vet when puppies. This condition is much easier to diagnose before the age of 12 weeks old. Although eye clear, both dogs could still have been carrying a copy of the gene.
Blood samples are taken from the dog and the paperwork countersigned by the vet. The samples are shipped to Optigen in New York State who carry out the test.
I am delighted to announce that both Sassy & Storm are genetically eye clear of CEA/CH.
More information on CEA can be found at http://www.collieeye.org.uk/ which includes a brilliant page on the genetic inheritance of this condition.
