Mitochondrial dysfunction plays an important role in the pathogenesis of Parkinson's disease. Primary genetic abnormalities in the mitochondrial DNA or nuclear DNA can cause parkinsonism. Mitochondrial parkinsonism presents with classical features of parkinsonism along with multisystem involvement. Genetic analysis is essential in reaching the diagnosis which is not always possible, especially in developing countries. Muscle biopsy can be a boon in this setting as exemplified in our report of two siblings where a diagnosis of mitochondrial parkinsonism was made on the basis of muscle biopsy.
