Therapeutic treatments of mtDNA diseases at the earliest stages of human development.
Chiaratti MR., Meirelles FV., Wells D., Poulton J.
More than 150 pathogenic mitochondrial DNA (mtDNA) mutations associated with a range of illnesses have been described in humans. These mutations are carried by one in 400 people and their inheritance is exclusively maternal. Currently there is no method to prevent mtDNA diseases, which highlights the need for strategies to predict their transmission. Here we outline the scientific background and unique difficulties in understanding the transmission of mtDNA diseases, explaining why their management has lagged so far behind the genetics revolution. Moreover, both current and future management options, including cytoplasmic and nuclear transfer, are also discussed.
