简介：
Overview
This protocol demonstrates the use of MALDI-TOF mass spectrometry to obtain a cardiolipin fingerprint from leukocytes, facilitating the diagnosis of Barth syndrome. The method allows for the rapid assessment of the monolysocardiolipin to cardiolipin ratio, which effectively distinguishes Barth syndrome patients from control heart failure patients with high sensitivity and specificity.

What is Barth syndrome?
Barth syndrome is a genetic disorder that affects the metabolism of cardiolipin, leading to various health issues, including heart problems.
How does the MALDI-TOF mass spectrometry work?
MALDI-TOF mass spectrometry is a technique that allows for the analysis of biomolecules by ionizing them and measuring their mass-to-charge ratio.
What is the significance of the monolysocardiolipin to cardiolipin ratio?
This ratio is crucial for diagnosing Barth syndrome, as elevated levels indicate the presence of the disorder.
Can this method be used for other diseases?
While this method is specifically designed for Barth syndrome, similar techniques may be adapted for other lipid-related disorders.
Is this method suitable for routine clinical use?
Yes, the method's high sensitivity and specificity make it suitable for integration into routine clinical laboratory diagnostics.
