What is short/branched chain acyl-coa dehydrogenase deficiency

Short/branched chain acyl-CoA dehydrogenase (SBCAD) deficiency is an inherited (genetic) condition. SBCAD is the name of an enzyme in your body that helps you digest a part of some proteins called isoleucine.

Without enough of this enzyme, the body has trouble digesting proteins that have isoleucine. It does not appear that this is harmful, as babies with SBCAD deficiency have very few, if any, signs and symptoms.

Treatment and Management

Most babies with SBCAD deficiency will not need treatment.

If your baby does have signs and symptoms of SBCAD deficiency, it is important to talk to your health care provider about which treatment(s), if any, your baby needs.
