Mitochondrial DNA depletion syndromes (MDSs) are a group of heterogeneous autosomal recessive disorders associated with a severe reduction in mitochondrial DNA in the affected tissues. The manifestations vary from tissue-specific mtDNA depletion to wide-spread multisystemic disorders. Some genes are known to underlie this group of disorders, and many disease genes are still unidentified. However, the disease mechanisms seem to be intimately associated with mtDNA replication and nucleotide pool regulation.
