Repeats, longevity and the sources of mtDNA deletions: evidence from 'deletional spectra'.

Perfect direct repeats and, in particular, the prominent 13 bp repeat, are thought to cause mitochondrial DNA (mtDNA) deletions, which have been associated with the aging process. Accordingly, individuals lacking the 13 bp repeat are highly prevalent among centenarians and overall number of perfect repeats in mammalian mitochondrial genomes negatively correlates with species' longevity. However...

Role of Mitochondria in Ataxia-Telangiectasia: Investigation of Mitochondrial Deletions and Haplogroups

Ataxia-Telangiectasia (AT) is a rare human neurodegenerative autosomal recessive multisystem disease that is characterized by a wide range of features including, progressive cerebellar ataxia with onset during infancy, occulocutaneous telangiectasia, susceptibility to neoplasia, occulomotor disturbances, chromosomal instability and growth and developmental abnormalities. Mitochondrial DNA (mtDN...

Mitochondrial DNA Mutations, Pathogenicity and Inheritance

Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...

Recombination via flanking direct repeats is a major cause of large-scale deletions of human mitochondrial DNA.

Large-scale deletions of mitochondrial DNA (mtDNA) have been described in patients with progressive external ophthalmoplegia (PEO) and ragged red fibers. We have determined the exact deletion breakpoint in 28 cases with PEO, including 12 patients already shown to harbor an identical deletion; the other patients had 16 different deletions. The deletions fell into two classes. In Class I (9 delet...

Double-strand breaks of mouse muscle mtDNA promote large deletions similar to multiple mtDNA deletions in humans.

Mitochondrial DNA (mtDNA) deletions are a common cause of mitochondrial disorders and have been found to accumulate during normal aging. Despite the fact that hundreds of deletions have been characterized at the molecular level, their mechanisms of genesis are unknown. We tested the effect of double-strand breaks of muscle mtDNA by developing a mouse model in which a mitochondrially targeted re...
