Altering the Mitochondrial Genome: Is it Just a Technical Issue?
Published online by Cambridge University Press: 01 July 1999
Technical, ethical, and social questions of germ-line gene interventions have been widely discussed in the literature. The majority of these discussions focus on planned interventions executed on the nuclear DNA (nDNA). However, human cells also contain another set of genes that is the mitochondrial DNA (mtDNA). As the characteristics of the mtDNA grossly differ from those of nDNA, so do the social, ethical, psychological, and safety considerations of possible interventions on this part of the genetic substance.
