However, in acid maltase deficiency, carnitine deficiency and debrancher enzyme deficiency, progressive muscle weakness, rather than exercise intolerance, is the primary symptom.
People with these deficiencies may, over time, develop mobility problems.
Cardiac Care
People with certain diseases such as debrancher enzyme deficiency, or carnitine deficiency may develop significant, or severe heart problems. The only symptom of this is heart failure. The disorder responds to carnitine supplemation.
Excercise Intolerance
