Automatic Translation

This protocol shows how to obtain a mass spectrometric "fingerprint" of leukocyte cardiolipin for the diagnosis of Barth syndrome. The assessment of elevated monolysocardiolipin to cardiolipin ratio discriminates patients with Barth syndrome from control heart failure patients with 100% sensitivity and specificity.
