Abstract Population-based studies of mitochondrial genetic diversity often require the classification of mitochondrial DNA (mtDNA) haplotypes into more than 2000 described haplogroups, and further grouping those into hierarchically higher haplogroups. Such secondary haplogroup groupings (e.g. “macro-haplogroups”) vary across studies, as they depend on the sample quality, technical factors of haplogroup…

Mitochondrial DNA and human mitochondrial diseases Mitochondria are organelles found in nearly all eukaryotic cells that are responsible for producing energy in the form of ATP through oxidative phosphorylation. Mitochondrial DNA (mtDNA) is a small, circular genome that is located within the mitochondria and is inherited maternally. Mutations in mtDNA…
