This method generates a cardiolipin finger printing of leukocytes by MALDI-TOF mass spectrometry and allows the measurement of the ratio between monolysocardiolipin and cardiolipin for a rapid diagnosis of Barth syndrome. The main advantage of thi

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.
