Genetics of mitochondrial diseases: when the nucleus talks to the mitochondrion

Thorburn David

The term “mitochondrial disease” (MD) encompasses well over 300 monogenic disorders. MD genes encode either components of the oxidative phosphorylation (OXPHOS) system or cause a secondary impact on OXPHOS. MD can be caused by pathogenic variants in any of the 37 mitochondrial DNA (mtDNA) genes, which explain up to 70% of adult-onset MD. In paediatric-onset MD, the modes of inheritance appear to be ~30% mtDNA, ~50% autosomal recessive with the remainder X-linked or...
