Diseases resulting from mitochondrial DNA point mutations.

Abstract excerpt

A number of mitochondrial DNA (mtDNA) mutations have been identified which cause familial, late onset neuromuscular degenerative diseases. These include missense mutations in most of the mtDNA polypeptide genes as well as base substitutions in several tRNA genes. Missense mutations in the mitochondrial electron-transport genes cause Leber hereditary optic neuropathy. Ten mutations have been associated with this...
