The mitochondrial DNA (mtDNA) depletion syndrome (MDS) is a clinically heterogeneous group of mitochondrial disorders characterised by a reduction of the mtDNA copy number in affected tissues without mutations or rearrangements in the mtDNA. MDS is phenotypically heterogeneous, manifesting either as a hepatocerebral form, a myopathic form, a benign 'later-onset' myopathic form or a cardiomyopathic form.
