MtDNA


Mutations in mtDNA cause human diseases.
A number of human diseases are caused by mutations in genes in our mitochondria:
cytochrome b
12S rRNA
ATP synthase
subunits of NADH dehydrogenase
several tRNA genes ...

mitochondrial DNA (mtDNA)
Circular or linear DNA of the mitochondria. It codes for only a small but essential part of the mitochondrial proteins and for genes for tRNAs and rRNAs.

Mitochondrial DNA (mtDNA) comparisons serve as a model for genome evolution and as a tool for reconstructing evolutionary relationships. Relative to the nuclear genome, this system has several advantages for a comprehensive sampling across life.

We have undertaken genomic transplantation studies involving the transfer of mitochondrial DNA (mtDNA) from PD patients with a complex-I defect to a novel nuclear background.

Critics raised an important point about the inferences based on the mtDNA studies: it is based on only a single, independently evolving gene region.

Wayne and Jenks, in a recent Nature, present a study of the mtDNA(mitochondrial DNA -- it's maternally inherited) of the endangered red wolf, Canis rufus. This species, once extending over a large range in the southeast, is now extinct in the wild.

Amerind mtDNA suggests two waves of migration (one perhaps as old as 21-42 thousand years ago). The genetic model confirms the accepted ideas about human migration into the Americas and suggests a possible fourth wave.
