Abstract

The molecular mechanisms by which the nuclear genome regulates the biosynthesis of mitochondrial DNA (mtDNA) are only beginning to be unravelled. A naturally occurring in vivo model for a defect in this cross-talk of two physically separate genomes is a human disease, an autosomal dominant progressive external ophthalmoplegia, in which multiple deletions of mtDNA accumulate in the patients' tissues. The assignment of this disease locus to 10q 23.3-24.3 is the first direct evidence for involvement of both nuclear and mitochondrial genomes in a single disorder.
