You Make The Diagnosis: Name The Rare Blood Disorder Found In Irish Setters

This beautiful girl is Liddie, an Irish setter with a big personality.  Liddie brightens any room she enters with her expressive and friendly face.  For this photo, she ignored me and listened to a dog in the room next door.  What a character! 

Irish setters have a rare but fatal genetic disease that causes fever, anorexia, recurrent infections, slow wound healing, weight loss, umbilical infections, gingivitis, lymphadenopathy, pododermatitis and osteomyelitis. Name this inherited disease. 

Dx:  Canine Leukocyte Adhesion Deficiency (CLAD)

Canine leukocyte adhesion deficiency is an inherited disease caused by a mutation in the leukocyte integrin CD18.  It is an autosomal recessive which means that dogs with only one copy of the gene will be asympotomatic carriers while those with two usually die young.  The disease is also seen in humans and cattle.  Since CLAD is a devastating disease, I recommend testing all Irish setters prior to breeding.  Your veterinarian will collect a blood sample and send it to Optigen for testing.  More information is available at http://www.optigen.com/opt9_test_clad.html.
