[Characteristics of molecular genetics and research progress on mitochondrial diseases].

Abstract excerpt

Mitochondrial diseases is a group of metabolic disorders caused by abnormal structure and dysfunction of mitochondrial DNA (mtDNA). Abnormalities of mtDNA include point mutations, deletions, and rearrangements and depletion of mtDNA. These may affect the ability of mitochondria to generate energy in cells of various tissues and organs. As many factors are involved in the regulation of mtDNA mutations, most...
