Detection of mitochondrial DNA (mtDNA) mutations.

Abstract excerpt

The maternally inherited mitochondrial DNA (mtDNA) is a circular 16,569bp double stranded DNA that encodes 37 genes, 24 of which (2 rRNAs and 22 tRNAs) are necessary for transcription and translation of 13 polypeptides that are all subunits of respiratory chain. Pathogenic mutations in mtDNA cause respiratory chain dysfunction, and are the underlying defect in an ever-increasing number of mtDNA-related...
