Abstract

Background. Mitochondrial myopathies are regulated by two genomes: the nuclear DNA, and the mitochondrial DNA. While, so far, most studies have dealt with mitochondrial myopathies due to deletions or point mutations in the mitochondrial DNA, a new field of investigation is that of syndromes due to mutations in the nuclear DNA. These latter disorders have mendelian inheritance. Results. Three representative cases have been selected: one with COX deficiency and a Leigh syndrome due to a SURF1 gene mutation, one due to a defect of Coenzyme Q synthesis and one with dominant optic atrophy due to a mutation in the OPA1 gene. Conclusions. Future developments will show that many neurodegenerative disorders are due to mutations of nuclear genes controlling mitochondrial function, fusion and fission.
