title: CoQ10 deficiency diseases in adults.
abstract: Deficiency of Coenzyme Q10 (CoQ10) in muscle has been associated with a spectrum of diseases including infantile-onset multi-systemic diseases, encephalomyopathies with recurrent myobinuria, cerebellar ataxia, and pure myopathy. CoQ10 deficiency predominantly affects children, but patients have presented with adult-onset cerebellar ataxia or myopathy. Mutations in the CoQ10 biosynthetic genes, COQ2 and PDSS2, have been identified in children with the infantile form of CoQ10 deficiency; however, the molecular genetic bases of adult-onset CoQ10 deficiency remains undefined.
