MCAD Deficiency – Cavalier King Charles Spaniel
Code: H755
Short description
Medium-chain acyl-CoA dehydrogenase (MCAD) is an enzyme that helps the body process medium-chain fatty acids, forming a key part of an animal’s metabolism.
General information
Medium-chain acyl-CoA dehydrogenase (MCAD) is an enzyme that helps the body process medium-chain fatty acids, forming a key part of an animal’s metabolism. A recessive mutation to the gene ACADM causes an MCAD deficiency (MCADD). This results in a build-up of medium-chain fatty acids, causing neurological symptoms such as fatigue and seizures. In dogs, MCAD Deficiency is found in the Cavalier King Charles Spaniel.

Clinical features
Dogs affected by MCADD experience a form of epileptic attacks known as complex focal seizures. These episodes are characterized by fatigue/letharghy, decreased awareness and responsiveness, and ataxia (a loss of coordination). They may last anywhere between 20 minutes to multiple hours. The onset of the disease is expected to be between 1 and 2 years of age.
