The 10 pages that link to Mitochondrial replacement therapy, each with the reason it gives.

• Mitochondrial DNACompared with: It can prevent transmission of pathogenic mitochondrial DNA, while raising ethical and clinical questions.

• Preimplantation genetic testingCompared with: It addresses some inherited mitochondrial disorders through intervention rather than embryo screening alone.

• Mitochondrial diseaseCompared with: It addresses inheritance risk before birth rather than treating established mitochondrial disease.

• Mitochondrial inheritanceRelated: It can alter which mitochondrial DNA is transmitted to an embryo.

• Mitochondrial dysfunctionCompared with: It addresses inherited risk before disease develops rather than repairing dysfunction in existing tissues.

• HeteroplasmyRelated: The procedure aims to reduce transmission of disease-causing mitochondrial DNA variants.

• Leber's hereditary optic neuropathyCompared with: Unlike treatments for existing LHON, it aims to prevent transmission of mitochondrial mutations.

• Barth syndromeCompared with: It concerns inherited mitochondrial DNA, whereas Barth syndrome is caused by a nuclear TAZ variant.

• Extranuclear inheritanceRelated: The techniques aim to reduce transmission of harmful mitochondrial DNA variants.

• MitochondriaBroader topic: It aims to reduce transmission of serious mitochondrial DNA disorders.
