Mitochondrial Myopathies

Living reference work entry

Abstract

Mitochondrial myopathies here imply the disorders of the respiratory chain that exclusively or predominantly affect the skeletal muscle (DiMauro and Gurgel-Gianneti 2006). They frequently present with multisystem dysfunction and have a broad variety of phenotypes and genetic etiologies. They can be classified genetically into two major groups: those due to mutations in mitochondrial DNA (mtDNA) and those due to mutations in nuclear DNA (nDNA). The prevalence of mitochondrial disorders as a whole is approximately 1 in 10,000 (Schaefer et al. 2008), although the carrier frequency of mtDNA mutations is about 1 in 200 (Elliott et al. 2008).
