Zusammenfassung: | Human mitochondrial diseases have been associated recently with mitochondrial DNA mutations, duplications and deletions which impair the protein synthesis of the mitochondrial subunits of the respiratory chain complexes. A constant feature is the coincident presence of the mutated and wild type genomes which provide heteroplasmy. The clinical expression of these diseases depends on the relative expression of each kind of mitochondrial DNA in the various tissues, which in turn affects the production of ATP in these tissues. Research on nuclear gene products interfering with mtDNA or with its gene products is the next step towards understanding the etiology of these diseases. |
